2 Product Description2. Descrip.

2.0 Product Description

The pHOx analyzer accepts syringe or capillary samples through a sample probe. The operator selects the sample mode via the keypad. The probe moves from its home position in the analyzer to an extended 45° position for syringe sampling. If the capillary sample is selected, the probe moves to a horizontal position that is back inside the capillary adapter.

2.1 Mechanical Assemblies

The analyzer is designed to calibrate using calibration stan-dards and reference solution contained in a reagent pack. The tubing automatically con-nects with the pHOx when the pack is placed into the analyz-er. Likewise, a space is pro-vided for a plug-in control pack. The content and se-rial number of the pack is coded in a “Dallas Semicon-ductor Add-Only Memory,” which is read by a One-Wire MicroLAN® system. The ana-lyzer has 4 major mechanical assemblies to move calibrator or sample in front of the biosen-sors.

Figure 2-1 Flow Diagram

2-2

pHOx Service Manual

2.1.1 Pump

The analyzer uses one pump (PN 21492) for 2 functions. The pump aspirates either sample or calibration standards from the sample probe, through the sensor module/reference electrode, through a solenoid actuated pinch valve, and delivers to the waste bottle of the reagent pack.The second function of the pump is to aspirate the reference solution from the reagent pack and deliver it to the reference electrode through a solenoid actuated pinch valve.

2.1.2 Sampler Assembly

The sampler assembly (PN 21504) utilizes a probe that rotates to 1 of 3 possible positions. The HOME position is vertical with the tip of the probe seated against a "Fluid Fountain” assembly that is the common port of the rotary valve.The syringe position is the probe tip extended out in front of the analyzer at ap-proximately a 45° angle. The capillary position is horizontal, but the tip is totally inside the capillary adapter. This allows the capillary to be used without a separate adapter. (This position is also used to change the capillary adapter.) The capillary adapter is pushed onto the end of the sampler. Extending the probe outward from the capillary position ensures that the probe will be seated inside of the adapter. The sampler will exert enough force to push the adapter off of the sampler if it is not aligned correctly.

2.1.3 Rotary Valve Assembly

The rotary valve assembly (PN 22215) has one common port connected to the sampler’s fluid fountain. Each calibration standard and quality control standard is connected to a port on the rotary valve. The rotor positions a central port con-necting one of the fluids to the outlet port. The outlet port is connected to the Fluid Fountain by the S-Line. Starting the pump aspirates the selected fluid into the flow path.The rotary valve's manifold also has positions that allow air to enter the S-line. Re-fer to the replacement procedures for actual positions.

2-3


2.1.4 Sensor Module Assembly

The Sensor Module Assembly contains the measuring sensors, flow cell, and preheater. The measuring sensors clip into place upon insertion. The sensors have contacts instead of cabled connectors. When mounted, the sensor module forces the sensor contacts to align with the matching contacts on the left/right intercon-nect boards. The module also contains the light sources and detector for the SO2% channel and 2 air detectors. Please refer to the drawing section and Appendix A for individual part numbers.

2.2 Electronic Assemblies.

2.2.1 Power Entry Module

The power entry module (PN 22818) provides the interconnect to wall power. The fuses are found in the accessory kit for the operating voltage (120 VAC PN 22814, 236 VAC PN 22817). The power entry module connects to the power supply through TB1.

2.2.2 Power Supply

The power supply (PN 21602) provides all of the power requirements for the ana-lyzer. The analog and logic voltage used in the pHOx are + 5VDC. The stepper motors are driven by +24 VDC. This module has no repairable parts inside. The power supply connects to the digital control board by TB2.

2-4

pHOx Service Manual

2.2.3 Digital Control Board

There are 2 Digital Control Boards: all units with monochromatic display use PN 24292, and all units with a color display use PN 40797. The main controlling board of the analyzer uses an Intel 386X processor with the following integrated peripheral functions:

• Clock and Power Management unit• Watchdog Timer Circuit• Asynchronous Serial I/O unit• Synchronous Serial I/O unit• Parallel I/O unit• Refresh control unit• JTAG- Complaint Test Logic Unit

The digital control board provides one 72 pin socket for a 4 MB SIMM module of RAM. This volatile memory stores the calibration, slope, and millivolt data.Major circuit identification:

U25 is the main clock generator; it is crystal controlled 14.318 MHz and a phase-locked-loop frequency generator. This generates a 50.11 MHz CPU clock, 14.318 MHz for VGA video timing, and 1.84 MHz for Baud rate generation.

U35 is the real time clock containing a battery which will retain the date/time, setup options, daily QC (up to 144 points), Error log (last 96 errors FIFO), and sample counter data. The battery has an expected 10 year life.

U37 PEROM stores the monthly (256 data points) and YTD QC data, QC setup information, and recognition of the QC fluid pack presence.

PCMCIA contains the operational program and boot program. This card must be in place for the unit to function.

U43 is the video control chip. U26 controls the printer output and the I/O ports Comm 1 and Comm 2. U36 is the DUART that controls the Comm 3 I/O port.

U16 provides the serial interface for the (RMS) interface and fluid pack memories.

The mechanical devices are controlled by U18. The Keypad and “home” sensors for the rotary valve and sampler are ported through U18. The stepper motors are 4 phase stepper motors. U18 controls the speed and direction each phase is pow-ered. U3 and U4 provide the power for each winding of the pump motor. U5 and U6 power each phase winding of the sampler motor. U7 and U8 power each phase of the rotary valve motor.U18 also provides the logic signal to operate the other mechanical devices. Typi-cally, the devices are connected to either 12 VDC or 24 VDC and the logic provides a ground path through a transistor. The waste valve solenoid (12 VDC) grounds through Q3, the reference solenoid (12 VDC) through Q4, the sensor module lamp (24 VDC) through Q6, and the preheater (24 VDC) through Q2. The 24 VDC valve boost circuit is on the board but not used on the pHOx analyzer.

Individual circuits are protected from an over current condition by the use of Posi-tive Temperature Coefficient Resistors (PTC). These resistors act as a direct short if the current is below a set current. If the current increases, the resistors heat up and open, similar to a fuse. When the device cools off, the connection is remade, allowing the circuit to function. The following lists these devices:

R22 - Solenoid common boost circuit (not used on pHOx)R24 - Heater power circuitR29 - Printer motor powerR43 - Print Head heater powerR44 - +24 VDCR45 - +5 VDCR71 - Bar Code Reader (+5 VDC out)R249 - Distribution board power (This board is mounted in the door.)

The LED indicators on this board are mostly unused. All will light at power up and then go off. The exception is D8 - 100 Hz Clock. D9 - 386 Strobe will appear to be always on. D7 is your program fail indicator and will come on with a software reset.Connectors:

2.2.4 Analog Board

There are 2 Analog Boards: pHOx, pHOx Basic, BiopHOx use PN 24291 and pHOx Plus, pHOx Plus L, and pHOx Plus C use PN 33390. U34 is the micropro-cessor that controls the signal acquisition and digital conversion. The signals are connected through several connectors.

• Left Sensor Interface board J6 - PCO2, pH, Reference, Air Detector (ADT) 4• Right Sensor Interface board J7 - PO2, Na+

• Sensor module J4 -SO2% detector, Preheater temp, ADT2, ADT3/Hct• Mechanical assemblies J3 - ADT1

Barometric pressure sensor U9 is on the analog board. The Analog to Digital Conver-sion (ADC) is performed by U31. The signals are multiplexed through U26 and U32.Preheater temperature control circuits are on the analog board. +24 VDC are ported through J3 to the SO2%/sensor module board (J4). The heater power wir-ing is protected on the digital control board by a PTC Resistor; the Heater has an in line thermostat (50°C) in the sensor module. The thermistor has 18.25 Kohms resistance at 37°C. The signal will change at a rate of 22.5 millivolts/0.1°C.There are 4 ADTs in the system. ADT1 holds the sample probe (40 uL setting). ADT2 at the inlet to the sensor module (70 uL). ADT3 is at the input to the sensors and is also used for the Hct. ADT4 is in the reference electrode housing.Logic and analog power is supplied to the analog board from the digital control board. Logic voltage (+5 VDC) enters J1 pin 14. The analog +5 VDC enter J1 pin 3 and -5 VDC J1 pin 4. The analog board provides power to the SO2 board through +5 VDC J4 pin 5 and -5 VDC J4 pin 6.

2.2.5 SO2 Control Board

SO2 Control Board is an integral part of the Sensor module. It controls the 2 LED light sources that glow at 880 nM and 660 nM, respectively.

2-7


2.2.6 Electrode Interface Boards

NOTE: The electrode interface boards are found only on pHOx and pHOx Basic.

The Electrode Interface Boards have 2 part numbers: PN 20641 (Left) and PN 20674 (Right). The electrodes are wireless. The electrodes have point contacts which engage the Interface board contacts when inserted into the sensor module. The left interface board, connecting to the analog board through J6, has 3 sets of contacts: one set for the reference electrode/ADT4, one set for Na+, and one set for PCO2 sensors. The reference electrode/ADT4 has 3 individual point contacts while the Na+ and PCO2 have 2 individual point contacts.The right interface board has 2 sets of contacts: one for the pH and one for the PO2 sensors; each consisting of 2 individual point contacts. This board is connect-ed through J7 to the analog board.

2.2.7 Door Assembly Electronics

The door assembly electronics include the Display Assembly, the Distribution Board, and the Keypad Assembly. The digital control board sends/receives signals to the door via the flat cable J104 on the distribution board.

NOTE: See Section 3.13 for part numbers that are model specific.

The keypad, which is glued onto the door, connects to the distribution board via J102 and has a ground cable clamped to the conductive surface on the inside of the door. The Analyze key also connects to the distribution board through this con-nector.The distribution board also provides the signal path to the display assembly and power to the display back lighting lamp. The display is a liquid crystal, graphics dis-play. It has a 320 x 240 dot matrix (1/4 VGA) yielding a 122 x 92 mm (4.99 x 1.33 inch) viewing area. This translates to a 40 x 20 character display using a standard character set. The display is backlit by cold cathode fluorescent tube (CCFT).An 8 ohm voice coil loudspeaker is mounted on the distribution board, producing all associated sounds.

4.0 Troubleshooting Information

This section contains suggestions for individual error codes, cycle information to help identify the cause of an error condition, and hints on basic troubleshooting.

1. Troubleshooting is recognizing the variance from normal operation. The calibration cycle can be used as the sequence of events where the cycle response and results are known.

Fluid Function Start cycle Std. A all 4 ADTs, Hct, PCO2, Na+, K+, iCa, Cl-, Gluc, Lact Std. B PCO2 Std. C pH, Na+, K+, Cl-, Gluc, Lact, (iCa on pHOx +L) Std. D all ADTs, pH, Hct, (iCa on pHOx+C)

PO2 uses Room Air (A-air position of the rotary valve). SO2/Hb utilizes external calibrators. (These are model specific.)

2. Sensor Methodology

ISE sensors - Na+, K+, iCa, Cl-, pH, and PCO2 ISE requiring a reference signal - Na+, K+, iCa, Cl-, pH ISE with its own internal reference - PCO2 Reflected Impedance - Air Detectors 1,2,4, 3/Hct Amperometric - PO2, Glucose, Lactate Optical Reflectance - SO2%

3. Calibrator Functions other than calibration.

PO2 Std. B is used to flush the system. PO2 is monitored on all fluids in the Calibrator pack. If the PO2 millivolt read-

ing varies from that of room air, a 72 Delta mV error is generated indicating a contaminated calibrator pack.

Std. D has surfactant and is used to clean the flowpath between pump cycles.

4-2

pHOx Service Manual

4. Dependencies (Refer to the quick reference guide in the appendix.)

Hct Calibrated Na+ required

NOTE: The pHOx Na+ is a 30 day expendable electrode.

SO2% Calibrated Hct and PO2 required Hb Calibrated Hct and SO2% required PCO2 Calibrated pH required

Calculated values will not be reported if a needed test is suppressed. P50 is reported only if PO2 is between 30 mmHg (4 kPa) and 75 mmHg (10 kPa).

5. Password protection - One password for Set Up, QC, and Service menus. Should the password be lost, enter the following number when asked for the password.

Date Code“Back-door” Password = (((month x 31) + day) x 137) + (year x 16)) + 5987 2 digits 2 digits last two digits

Example: If today is 02 January 2003 the “back-door” password would be:

Password = (((01 x 31) + 02) x 137) + (03 x 16)) + 5987 = (33 x 137) + 48 + 5987 = 4521 + 48 + 5987 = 10556

Change the password to a known value and write it down.

4.1.1.2 Service Flow test

Pressing the soft key under the Service Flow Test brings up a screen that displays the results of this test. On this screen, pressing the soft key under Run Test causes the unit to pump each fluid twice: once with the Reference valve shut and once with the Reference valve Open.The expectation is that the flow time will increase with the decrease in vacuum caused by pumping reference solution into the waste line junction in the reference electrode. Ideally the 2 pump windings are equal and the flow time will double with the reference solenoid valve open. The pumping times will yield 2 pieces of information:

1. The individual flow times appear at the end of pumping that fluid.2. All the fluids will pump at the same rate. Usually Standard D is the one stan-

dard that varies in flow rate from the other fluids. A good rule of thumb for the flow rates is

pHOx Basic/BiopHOx and pHOx is in the 1000 – 1200 range.pHOx Plus/C is in the 1200 – 1300 range.pHOx Plus L pumps in the 1300 – 1400 range.

4-6

pHOx Service Manual

At the end of the Test, the Average flow time for Reference Valve Closed and Reference Valve Open is displayed. A ratio of the average times is presented. The ratio should fall between 0.5 – 0.65.

• Ratios approaching 1 indicate the loss of reference flow.• Ratios approaching 0.0 indicate an obstruction or air leak in the system

before the flowpath reaches the Reference electrode.

4.2 Flow Problems

NOTE: Each of the following troubleshooting procedures has an associated flow diagram that may be found at the end of this chapter.

General procedures when isolating flow problems:

NOTE: Refer to the FLOW TEST decision tree. Do not be con-fused with the Flow Test Cycle that only shows the flow times.

Unit calibrates, but the sample will not aspirate. This usually means you have an air leak into the system. The sample, being more viscous than the aqueous standards, causes more vacuum to be created by the roller pump. If a membrane is leaking, this increase in vacuum will pull the aqueous fill solution from the electrode, easier than pulling sample from the probe. Likewise, a poor connection at the intercon-nect tubing or between the electrode sealing washer and the sensor module will allow air to enter easier than pulling sample up the flow path.

• Check the connections between probe and sensor module, sensor module, and reference electrode.

• Check the electrodes for the loss of internal fill solution.• Check the flow cell window during a pump cycle, looking for bubbles entering

the flow path or pump and waste tubing.

A No flow or obstructed flow cause can be isolated by performing the FLOW TEST. The fluidic system can be isolated into three large sections. This will limit the area of your search. The 3 sections are Fluid Pack to Fluid Fountain, Sampler/Sensor module, and W/R to Waste tubing. Use the SYSTEM TEST screens to control the mechanical devices.

1. Extend the sampler to the syringe position.2. Open the waste line solenoid.3. Turn on the pump and attempt to aspirate water then air from a sample

cup.4. If water is aspirated from the cup, the sample probe, sensor module, external

tubing, and waste line are functioning. The problem exists between the Fluid Fountain and Fluid Pack.

5. If water is NOT aspirated from the cup, remove the tubing from the outlet port of the Reference electrode. Place it in a cup of water.

NOTE: This assumes the waste solenoid has functioned and is not pinching the tubing.


4-11

6. If step 5 fails to aspirate from the cup, the problem lies between the W/R tubing and the waste bottle of the Fluid Pack.

7. If Step 5 does aspirate water, the problem is in the Sampler/ Sensor mod-ule.

4.2.1 Isolating a Plug in the W/R to Waste Tubing

NOTE: If the reference flow is obstructed, the sample may not stop in the sensor module due to increased vacuum. Flow time decreases due to increased flow rate.

1. Disconnect the waste tubing from the reference electrode and place in a cup of water. If water is NOT aspirated, there is a plug.

2. Lift the waste tubing out of the waste solenoid. If flow starts, the valve is dirty. Clean the dirt from the waste solenoid or replace it.

3. If flow does NOT start, remove the waste line from the front panel connec-tion. If water flows from this tube there is a plug in the internal waste tubing or waste bag of the fluid pack.

4. Turn off the pump. Connect a syringe of water to the waste port on the front panel. Attempt to inject water through the line to clear the plug.

5. If there is no flow, remove the Fluid Pack to ensure the problem is not a poorly seated or damaged waste connection. Should the problem continue, replace the internal tubing set.

4.2.2 Isolating a flow problem in the Sampler/Sensor module

1. You noted flow when aspirating from the waste tubing in step 2 of Section 4.2.3.

2. Raise the Sampler to the Syringe position. The Pump should be OFF for this test.3. Connect a syringe of water to the reference electrode outlet port. Attempt to

inject the water.4. If water flows freely, air is entering the system preventing aspiration.

a. Inspect each electrode to assure the internal fill solution level is not dropping.

b. If yes, replace the electrode or membrane as required.c. Inspect the seal between the reference electrode and sensor module

(interconnect tubing) .

NOTE: If the flow path starts to empty while the syringe is still attached, only the water below the leak will leave the flow path out of the tip of the probe.

4-12

pHOx Service Manual

d. Inspect the sensor sealing washers for distortion or misalignment. Re-place as necessary.

e. The seal between the air detector and the sample probe may be tested by attaching the syringe to the sample probe, blocking the air detector outlet tube. Apply pressure to the syringe and look for water leaking out.

5. If water does not flow freely, there is a blockage.a. Loosen the reference electrode. Water should pass through or the

electrode is plugged. Flushing with cleaning agent or hot water may free the blockage.

b. If the reference is clear, reinstall it and remove the bottom electrode. c. Apply a moderate pressure with the syringe.d. If water does not enter the sensor module of the bottom electrode the

blockage is above it.e. Removing one electrode at a time. Look for water entering the sensor

module. If no water enters the module as the electrode is removed, the plug is above it.

f. If water did enter the bottom sensor module in step C above, the plug is in the Sample Probe/Air detector. Remove these assemblies and flush through them or replace them.

4.2.3 Isolating a flow problem between the Fluid Pack and the Fluid Fountain

If you have successfully aspirated a sample, but the analyzer will not calibrate or aspirate on-board controls, proceed as follows.

1. Position the sampler in the syringe position and inspect the capillary adapter for signs of wear. Replace if necessary.

2. Lower the sampler to the Home position; connect a syringe to the reference outlet port.

3. Remove the analyzer cover.4. Disconnect the S-Line (center tube) from the rotary valve.5. Inject the water and look for flow from the S-Line.6. Look for a leak between the fluid fountain and the capillary adapter. Realign

if necessary.7. If there is no flow from the S-Line, remove the fluid fountain/S-Line and

flush with hot water or cleaning agent, or replace the assembly.8. If there is free flow through the S-Line, the problem is in the rotary valve,

tubing harness, or connection to the fluid pack.9. Reconnect the S-Line and remove the fluid pack.10. Move the rotary valve to all the possible positions, observing which ports do

not allow flow.11. If there is no flow in ALL positions, remove the valve and clean or replace it.


4-13

12. Remove the tubing for each position that does not flow freely.13. If water can be flushed through the individual lines, remove and clean or

replace the valve.14. If water cannot be flushed through the affected lines, replace the tubing har-

ness.

4.3.1 Analyte Troubleshooting ( Series code 1-6 and Digit codes 1-4)

Multiple Channel failures:Slope

• Ensure the Reagent Pack is fully plugged in. • The pack box edge closest to you should

lie inside the small lip of the chassis. • Check the flow times displayed on the

service screens.• Inspect the Reference tubing to assure

flow.• Inspect the waste line

for bubbles.• Prime the system,

check each fluid for air.• pH and Na+ require

a working reference electrode.

Figure 4-1 Reagent Pack Placement

• Note if the channels that fail use the same standard from the fluid pack.• Loss of the +5 Vdc on the analog board• Loss of the Analog board A/D/ converter• Loss of +5 Vdc to the Analog Board• Analog Board over heated (PTC resister open) - If unit is allowed to cool off

by shutting it off for 5 minutes. Investigate why the unit or Analog board is overheating.

Dependency Rules

• Hct requires calibrated Na+ for calibration and results.• PCO2 requires calibrated pH for results (pH checked on standards to assure

bicarbonate is correct).• SO2 requires calibrated Hct and PO2 for results. Calculated SO2% is re-

ported if measured SO2 is not available.• Hb requires Hct and SO2 for reporting. Priority:

1. If linked with COOX, the COOX HGB is reported.2. If no COOX link, the measured result is reported, if available.3. If no COOX or measured result, the calculated result from the Hct reading

(Hct/3) is reported.4. If no COOX, no measured, and no Hct, the default value (Hb) is re-

ported.


4-19

• P50 is measured and is reported only when PO2 is between 30-75 mmHg. P50c is reported when PO2 is outside those limits. P50 also requires cali-brated SO2% and Hb/Hct for reporting.

• Qsp/Qt requires 2 separate blood samples for determination: mixed venous and arterial.

• RI utilizes input or default FIO2% for calculation.• Calculated Results require calibrated and proper results by measured tests

used in the calculation.• Suppression rules - If measured test is suppressed in the Setup, the calcu-

lated results based on test also will not be shown or printed.• Password (One) is used for Setup, Service Menu, and QC. (No user pass-

words are available.)• Interfaces are NOVA COOX, PDM, and ASTM.• Standby Mode: There is no time dependency. Analyzer will prime and calibrate after coming

out of standby. Idle pumping is active, but no fluidic or gas calibrations are performed. Features Auto-Wake-Up, Auto-Cal, and Auto-QC• Micro Sample Analysis: Micro-Mode Tests: pH, PCO2, and PO2 Stepped Analysis: Stage 1 = Tip of probe to ADT1 (40 µL) Stage 2 = Up to ADT3 Stage 3 = Between ADT3 (up to ADT4): Other Tests Reading (including contact with reference electrode)

Instability

• Inspect sensor module for bubbles during the measurement cycle• Ensure that the waste valve stops the fluid flow during analysis. Fill the flow

path with any standard, raise the probe to the syringe position Look for droplets forming at the sampler tip.• Ensure that the waste and Reference solenoid valve are functioning.• Fill the flow path with any standard and view the system test screen. The signals should be steady and there is no flow of fluid there are three Possible conditions, a loose sensor module, an analog board failure, or a

poor connection between a set of electrodes and an interconnect board.• Inspect the electrode washers to assure proper alignment. Nonalignment

may cause a flow problem.• In rare cases the tubing harness may have become contaminated. Using the clean-

ing adapter, flush the system with cleaning agent followed by distilled water.

4.3.2 Single Channel Failures

SlopeView the Sensor Subsystem screens. If the change in millivolts between standards is 0 or less than that mentioned in Section 4.3.1, there are several possibilities:

• Membrane or sensor has reached the end of its use life.• Bubble of Air is covering the sensing material at the electrode tip.• The electrode is not making good contact with the Interconnect board con-

tacts.• Loss of the Analog board multiplexer will cause a zero input to the A/D con-

verter.• Ensure calibration on required channels: Sodium is required for Hct, Hct is

required for SO2%.• Viewing the Sensor subsystem screens you note an overload condition (999.9 mv).• Check for NO connection to the Interconnect board.• Check the PO2 /PCO2 for loss of the Internal Fill solution (membrane rup-

ture).• Loss of the multiplexer or individual channel circuit on the Analog board.• The pH electrode may need conditioning. • Na+ sensor over 30 days of use. The Na+ sensor will be destroyed by con-

ditioning.

InstabilitySingle channel instability is seldom a flow problem unless a standard is unique to a particular channel.

• De-bubble the electrodes.• Ensure a good connection between the electrode and the Interconnect

Board.• Ensure a good connection between the sensor module and Chassis.• Ensure the analyzer's door is closed and the ground strap is making good

connection.


4-21

4.3.3 Temperature Problems

• Ensure that the room ambient temperature is within specification ( 18o - 32o C).• Ensure that the sensor module is plugged in correctly.• View the Analog Input screen channel 20. This channel will be a 0 if the

module is at 37o C and change at a rate of 22.5 mv/1oC, + if above and - if below 37o C.

• The power for the preheater comes from the digital control board.• The heater control circuitry is on the analog board.

4.3.4 Air Detector (ADT) Problems

• Air Detectors are only calibrated during a 2-point calibration.• Typically the Fluid /Air millivolt difference will be about 700.• Check the sample probe for air being introduced below the sensor mod-

ule.• Check the sensor module for air being introduced at the electrode/sensor

module seal.• Ensure that the electrode sealing washers are centered and seated correctly.• The Air detector signals are processed by the analog board. They are only

displayed on the System Test screen. Alternately aspirate air and then fluid to see the change in the signal.

NOTE: Remember to turn on the air oscillator to obtain an ADT reading.

• Flow Test- During a flow test, the rotary valve rotates to each fluid position.- The pump turns on to fill the lines from the rotary valve S-line port to

the ADT1.- The rotary valve rotates to an air position.- The pump turns on and the time in milliseconds until the ADT senses

air is recorded.- The time is normally 1200 msec. The acceptable range is 100 to 1700

milliseconds.• Run a Flow Test; press the soft key on the Service screen.

- Typical result for Standard A, B, C, D is 1300.- If all are high (3000-5000), there is a flow path obstruction.- If only one is high,

1. Check for correct fluid pack installation.2. Check that the valve is in the correct position.3. Connect a syringe to the S-line port of the valve. Remove the

reagent pack and move the valve to each position. Verify that the link is clear by purging air through the S-port.

pHOx Service Manual

Dependency Rule and Setup Information:HCT Requires Na+ calibrated for calibration/results.PCO2 Requires pH calibrated for results. (pH checked to assure bicarbonate

is correct.)SO2% Requires Hct calibrated, uses SO2%c if measured SO2 is not available.Hb Requires Hct and SO2 for reporting. Hb method priority: (1) If linked with COOx, then COOx Hb will be reported. (2) If no COOx link, measured results are reported (if available). (3) If no COOx or measured result, calculated result from Hct reading

(Hct/3) is reported. (4) If no Coox, no measured, and no Hct: Reports ‘Default’ Value (Hb).P50 Measured Reported only with PO2 between 30 and 75 mmHg. Also requires calibrated SO2% and Hb/Hct for reporting.Qsp/Qt Requires 2 separate blood samples for determination: Mixed Venous

and Arterial.RI Utilizes input or default FIO2 % for calculation.nCa pHOx-Plus Only. Requires properly installed/calibrated iCa and pH.Anion Gap pHOx-Plus Only. Requires properly calibrated/installed Na+,K+,Cl-, PCO2.Calculated Results require calibrated and ‘proper results’ by measured tests used

in calculation.Suppression (Hb): Only Hb can be suppressed: Option to turn Hb from measured

to calculated (one or the other will always appear).

Passwords:• One password (System Password) for Set Up• 200 user unique passwords available - 3 levels of priviledge:

1. Privilege Level 1: Operators have access to all areas of the analyzer except those protected by the existing System Password. Level 1 opera-tors do not require PDM review and may override this feature. Level 1 operators can override QC lockout.

2. Privilege Level 2: Operators have access to all areas of the analyzer except those protected by the existing System Password. Level 2 op-erators DO require PDM review, but may override this feature. Level 2 operators cannot override QC lockout.

3. Privilege Level 3: Operators have access to analysis only. Level 3 op-erators require PDM review and cannot override this. Level 3 operators cannot override.

Test Suppression: If measured test is suppressed, any calculated/associated tests will also be

suppressed. Tests still will be calibrated w/errors displayed on suppressed channels.

QC Lockout:Mode A Lockout:

If lockout enabled, and tests fail, unit can be ‘unlocked’ by running any control level and passing all tests.

Mode B Lockout: If lockout enabled, and tests fail, unit can only be ‘unlocked’ by running

specific control level(s) that failed and passing all tests.QC Storage Options:

Mode A QC Storage: If all QC results ‘pass’ range limits, QC results are automatically stored

in memory. If any results ‘fail’ range limits, all results will remain on unit display until either user accepts/rejects results or another QC or sample result is run/displayed (at which time past [non-released] QC results) will be deleted.

Mode B QC Storage: All QC results, whether passing or failing range limits are automatically

stored in memory at end of control analysis.Glucose (Overrange Testing) pHOx-Plus/C/L only:

Gluc Overrange Solution included in Reagent Pack: Done Automatically Daily; Elimination of manual - ampule running of Performance Check Solution

Automatic Glucose Performance done at operator-programmed time daily. (Nova recommends to set time at 5:00 AM for optimum performance.) PASS - FAIL is reporting. Change Gluc Membrane if test lists as FAILED and

repeat.Glucose Auto Polishing Cycle: Automatic polishing of Gluc sensor occurs each day at midnight, followed by 2-point cal, and additional 2-pt calibrations at 2 and 4 AM.
