Introduction

GrayWolf Sensing Solutions provides a fully integrated system for measuring indoorair quality and ventilation. A laptop computer (Lap PC) running WolfSense™ IAQLAP software takes readings of air quality from a probe connected through the serialport. You may choose to view live readings as they happen, plot readings for aselected measurement parameter in real time and/or log the readings for future use.Later, you may use WolfSense™ PC software on the Lap PC to open files of loggedreadings for printing, graphing or exporting to a word processor or spreadsheet.

In the DirectSense™ 100 kit, the probe (model IQ-410) has four sensors whichprovide five measurements: Temperature (°F/°C), Relative Humidity (%RH), DewPoint, Carbon Monoxide (CO), and Carbon Dioxide (CO2). The Dew Point is derivedfrom Temperature and Relative Humidity readings.

In the VentCal™ 100 kit, the probe (model CD-201) has two sensors which providemeasurements of Carbon Dioxide, Temperature, and Outdoor Air (OA) ventilation.VentCal™ software (SOFT-VENT) upgrades the DirectSense™ 100 kit to include allVentCal™ capabilities.

This manual will get you started. Help files are available in all WolfSense™ software.

Powering

The Lap PC will run using its own battery pack or with the help of the AC adaptersupplied with the Lap PC. Before first use, charge the battery according to theinstructions in your Lap PC manual.

NOTE: Charge your Lap PC batteries frequently to avoid data loss.

Like the Lap PC, the probe runs on batteries or with an AC adapter. The probe usesonly alkaline batteries. The GrayWolf kit provides two D cells and a 110VAC adapter(240VAC in Europe) for the probe. WolfSense IAQ LAP software will warn you if theprobe’s battery voltage is low. If, when you plug in the probe, its batteries are flat, youwill see “No Probe Attached” in the upper left-hand corner of the Lap PC screen.

Changing Batteries on the Probes

Hold the top of the probe with one hand and the handle with the other.

Twist the probe handle in a counterclockwise direction.

Remove the old batteries.

Insert 2 new D-cell alkaline batteries, ensuring that the battery positive is tothe top.

Carefully screw the handle back onto the probe, ensuring not to cross-threadthe handle or overtighten it.

When setting up the Lap PC to work only from a battery pack for an extended periodof time, refer to your Lap PC user manual for tips on conserving battery power. If theLap PC’s batteries become depleted, a warning message is issued and thenWolfSense IAQ LAP will automatically stop logging and suspend the Lap PC.

Figure 2 - Using an AC Adapter to Power the Probe

The ACC-ADY-L9 serial/AC power adapter allows youto power the probe with an AC adapter if you will betaking readings longer than the expected life of thebatteries. It has a serial adapter and an AC powersocket.

Data Organization: Sites and Locations

Logged readings are stored in individual data files called location (.loc) files.Calibration data, text notes, drawing notes, and template reports are also stored andorganized as attachments to these location files (see “Notebook” on page 13).Location files are stored in the Windows folder which WolfSense calls site folders orSites. WolfSense IAQ LAP and WolfSense PC software use the same Windows filestructure of site folders and location files on the Lap PC. If you create a location filein WolfSense IAQ LAP, you will be able to open it from WolfSense PC.

Each site folder may contain multiple sub-sites and multiple location files to furtherorganize the data. For example, a site folder called "School" may have one sub-sitefor the "Ground Floor" containing locations for the "Principals Office" and "Library"and another sub-site called "3rd Floor" containing a location for the "TeachersLounge." The root site in the WolfSense file system is \My Documents\WolfSense\,so the three location files would have these file names:

\My Documents\WolfSense\School\Ground Floor\Principals Office.loc\My Documents\WolfSense\School\Ground Floor\Library.loc\My Documents\WolfSense\School\3rd Floor\Teachers Lounge.loc

Probe Calibration

The probe may be calibrated in one of three ways: at the factory, according to GrayWolf standards; at the factory (or an outside calibration laboratory) using NIST-certified

traceable standards; by the user (described in this section).

You cannot change factory and NIST calibrations.Temperature is factory-calibrated. Dew Point

*, which is

derived from Temperature and Relative Humidity, has nocalibration.

The three parameters you may change are Relative Humidity(%RH)*, Carbon Monoxide(CO)* and Carbon Dioxide (CO2).The range for each parameter has two pre-set calibrationpoints. Normally, you only change these points to matchreference gas or salt values for calibration.

Calibration should be performed at least every 12 months onthe %RH sensor and at least every 6 months on the CO andCO2 sensors. More frequent calibration is recommended ifthe sensors are exposed to contaminants such as heavycigarette smoke. Note that most IAQ monitoring protocolsadvise calibrating CO and CO2 sensors more frequently.

The probe should be returned to the factory for temperaturecalibration every 24 months. WolfSense provides kits for %RH,CO and CO2 calibration. See “Probes & Accessories” on page31 for the contents of each kit.

To set up the correct calibration environment for CarbonMonoxide(CO)* and Carbon Dioxide (CO2), place the flowhoodover the probe (Figure 35). For Relative Humidity (%RH)*,place the probe upside down in the adapter on the jar of saltsolution (Figure 36).

* DirectSense only.

Figure 35 - CalibrationEnvironment for CO or CO2:Flowhood over probe

Figure 36 - CalibrationEnvironment for %RH:Probe adapter on jar of saltsolution

21

Note: If WolfSense detects that a sensor may have drifted out of specification,

the icon will appear, along with a * next to the parameter that may need tobe checked. However, do NOT rely on this indicator to ensure propercalibration because WolfSense can only detect sensor drift in some instances.

To calibrate the probe, click on or tap Probe,Calibration.

Click on or tap the arrow to see the drop-down list ofuser-calibrated parameters.

Click on or tap the parameter you want to calibrate.

Click on or tap the high or low point value.

Edit the CAL POINT to match your reference value, ifnecessary. CAL POINT must match the gas or %RHreference you use. Recommended STABILITY TIME is 60seconds, but you may edit it if you wish.

Click on or tap Calibrate to begin the calibrationprocess.

Optional: Click on or tap Default to force all calibrationsto revert to the factory defaults for calibration points andstabilization times initially supplied by GrayWolf.

Optional: Click on or tap Clear to remove the currentcalibration. If a user calibration is cleared, the probe willuse a NIST calibration (if available) or the factorycalibration.Clear affects only the selected calibration point.

If you changed the calibration point value, you will beprompted to confirm this action.

WARNING! Confirming this action willoverwrite the existing calibration settings.

Click on or tap Yes.

Place the probe in the appropriate calibrationenvironment.

Start the flow of gas for CO or CO2, or place theprobe in the %RH jar.

Wait for the readings to settle within a range ofroughly 2-3%. This typically takes under 2 minutesfor CO and CO2, but 45-60 minutes for %RH.

Click on or tap OK.

Maintenance, Cleaning, Service

Lap PCPlease refer to your user manual for specific instructions on the care of your Lap PC.

ProbeThe probe requires very little maintenance: battery changes, periodic calibration, COsensor replacement (typically every 24-36 months), dusting.

See “Powering” on page 2 for details on battery changes.

The %RH, CO and CO2 sensors may be calibrated in the field following theinstructions in “Probe Calibration” on page 20. The temperature sensor is calibratedat the factory. It is recommended that you return your probe to GrayWolf for anannual factory recalibration and check-up.

The CO sensor has an expected operating life of approximately two years.WolfSense IAQ LAP checks the output of the sensor during calibration and, as theCO sensor nears the end of its operating life, warns you that the sensor needs to bereplaced. You may order a SEN-CO1 replacement sensor from GrayWolf or returnthe probe to GrayWolf to have the sensor changed.

To change the CO sensor yourself:1. Unscrew the probe handle from the probe body. (See Figure 3 on page 2.)

2. Carefully remove the black cap from the top of the probe. This is a press fit and the cap cannormally be removed by hand.

3. Cut the tie that is holding the CO2 and CO sensors.

4. Unplug the CO2 cell.

5. Unplug the CO cell.

6. Plug in the new CO cell.

7. Plug in the CO2 cell.

8. Fix cells in place with a new tie.

9. To reassemble the probe, use the reverse procedure.

Before using the probe with the new sensor, calibrate the CO sensor using theprocedure described in “Probe Calibration” on page 20.

When not using the probe for a period of time, store it in a cool, dry, dust-freeenvironment. The recommended storage temperature is 32ºF to 70ºF (0ºC to 21ºC).If the storage period will be more than four weeks, remove the batteries from theprobe before storing.

28

If the outside of the probe becomes dirty, you may clean it using a slightly damp cloth.It is not recommended that you clean inside the probe. If the inside does get dirty ordusty, the probe should be returned to GrayWolf for servicing.

Summary of Cautions

Avoid operation in direct sunlight as %RH measurements may become erratic.

Do not immerse the probe in water.

This is a precision instrument. Do not drop the probe or subject it to undue vibrationor shock.

When not using the probe for a period of time, store it in a cool, dry, dust-freeenvironment. The recommended storage temperature is 32ºF to 70ºF (0ºC to 21ºC).If the storage period will be more than four weeks, remove the batteries from theprobe before storing.

Do not place the probe in an environment where condensation will form on it. TheCO2 sensor is an optical sensor which uses an active detector and a referencedetector for stable long-term readings. If condensation has formed on one of thedetectors or if there are temperature differences between the two detectors, CO2readings may be erratic until the sensor has stabilized to its new environment.

29

Troubleshooting

Symptom – The WolfSense software has locked upPress CTRL-ALT-DEL.In the dialog box, click on or tap WolfSense IAQ LAP (or WolfSense PC).Click on or tap END TASK.Restart the WolfSense software from the LAP PC desktop.

If the system does not respond, from the Windows Start Menu, click on or tap ShutDown. Restart Windows.

If the system still does not respond, you will need to perform a hard reset.Push the Reset button to reboot.

Symptom – No communication with the probeCheck to ensure that: The probe is plugged in properly. The probe has good batteries. The battery contacts are clean and not corroded. The CO2 sensor is flashing (visible through the slots) to indicate power is on. Another application on the Lap PC has not locked the use of the serial port. The

COM indicator appears in the lower right-hand corner of the WolfSense LAPwindow when the COM port selected in Probe, Setup is available. If the COMport is unavailable, you may have to shut down any applications that use theserial port or restart your computer.

Symptom – Bad or erratic CO2 or %RH readingsCheck to ensure that: The probe is shielded from direct sunlight. Readings from these sensors can be

affected by strong direct light.

Symptom – Bad or erratic CO2 readingsCheck to ensure that: The sensor is plugged into the circuit board. You have not moved the probe from a cold environment to a relatively warm,

humid environment. The probe is not in a variable temperature air stream.The CO2 sensor is an optical sensor which uses an active detector and a referencedetector for stable long-term readings. If condensation has formed on one of thedetectors or if there are temperature differences between the two detectors, CO2readings may be erratic until the sensor has stabilized to its new environment.

Symptom – CO2 sensor continues to flash after Lap PC is turned offIt is normal for the sensor to flash for a minute or two after power-down.
