1. introductionThank you for purchasing the B & KPrecision Model 570A Hand HeldLinear IC Tester.

The basic function of the B & K Model570A Linear IC Tester is to test a linearIC for correct logical functioning asdescribed in the manufacturer’s IC datasheets. The B & K Model 570A applies the necessary analoguesignals to the inputs of the IC, monitoring the outputs at each stageand comparing them with the expected voltages. Any discrepancyresults in a FAIL indication and the faulty pins are shown on theintegral display. Additional facil ities are also provided, amongstthem test loops that can be used for goods inwards inspection,detecting intermittent faults or simply providing a rapid method ofexercising any IC for demonstration or educational purposes. Sincethe B & K Model 570A contains an extensive IC library, it is notnecessary to program the unit yourself other than to key in the ICnumber. It is also capable of identifying an unknown IC using theSEARCH mode - this is a feature that many users will find extremelyvaluable.

The B & K Model 570A is provided with an RS-232 interfaceenabling it to be connected to a companion software packagecalled CompactLink running on a PC. CompactLink allows testprograms for ICs not included in the internal l ibrary to be developedand downloaded into the B & K Model 570A memory to enhancethe library according to your wishes.

2. DC inputThe B & K Model 570A is powered by four AA batteries or by theuse of the battery eliminator input at the rear of the case. To insertthe batteries, turn the unit upside down and remove the battery



cover by removing the two cross head screws holding it in place.The batteries must be inserted in the correct orientation, asindicated by the drawing within the battery compartment. Incorrectinsertion of batteries will not allow the unit to operate. Replace thebattery cover and insert the screws. If the battery voltage falls toolow, a low battery warning symbol will be displayed at the top lefthand cell of the display in normal operating mode. A low batterywarning will also be displayed during a result display. Test resultsmay be inconsistent under these conditions.

3. battery eliminatorAn external battery eliminator is available for prolonged use of theB & K Model 570A. Some ICs consume a significant amount ofcurrent when powered up, and battery life can be conserved byusing the eliminator. There is no need to remove the batteries priorto inserting the battery eliminator. However, please note that duringprolonged periods of non-use batteries are prone to leakage andshould be removed. Note that to avoid damage to the unit westrongly advise that you only use the recommended batteryeliminator that is available by contacting your distributor. Note thatusing an incorrect battery eliminator voltage may damage the unitand invalidate the warranty.

4. switching onTo switch the unit on, simply press the 'ON' key. To preserve batterylife, the unit powers itself off after approximately three minutes ofnon-use or when “Sw Off” is selected from the main menu. Whenthe unit is switched on, it first performs a self-diagnosis test.Therefore, before switching on, check that the test socket is empty toprevent interference with the diagnostics. If the unit passes the self-test, a pass result wil l be displayed on the screen. Press a key toenter the main operating mode - the display will be as follows:

NO:

MODE:Single :RDY



When this initial display is obtained the B & K Model 570A is readyfor use. If, however, the message SELF-TEST FAIL: is displayedalong with a fault message, this indicates that a self-test diagnosticfault has been detected. Any detected faults will be displayed oneat a time. Pressing the TEST/EXEC key will then revert to theopening menu as above, but of course operation of the unit willthen be suspect. Before contacting your distributor, check that thetest socket is completely empty.

5. operating modesThe B & K Model 570A has a number of test modes that areselected using the MODE/CLEAR key from the initial screen. Thetest modes are as follows:

Single - execute a single test on the IC in the socket.Loop - execute test repeatedly, regardless of the result.P Loop - execute test repeatedly, provided the result was PASS.F Loop - execute test repeatedly, provided the result was FAIL.Search - identify the number of the IC in the socket.Diags - execute the diagnostic self-test.CmLink - enter remote mode for CompactLink software.Sw Off - turn off the unit

6. entering test numbersPress the MODE/CLEAR key until the desired test mode is displayed.Enter the number of the IC you wish to test. Pressing theMODE/CLEAR key will clear the last digit from the display if amistake is made.

Note: The NUMERIC information only is entered, leav ing out themanufacturers prefixes and suffixes and IC family information.As an example, all the following linear ICs should be entered as7, 4, 1 on the keypad:

e.g. uA741CP, uA741M, uA741C etc



Some ICs are available in different pin outs or package types, andalso there may be several different types of IC with the samenumerical part number. In these cases the B & K Model 570A willautomatically determine which test to perform. If however the IC isfaulty the unit may not be able to determine the correct IC type - ifthis happens a warning message will be displayed. A complete listof all ICs supported by the B & K Model 570A is contained in the ICSUPPORT LIST at the end of this manual together with notes onany special requirements for certain ICs.

Note that if you have stored a user library using CompactLink, an ICin the user library with the same number as one in the internall ibrary will take precedence. This allows a new test to be written foran existing IC. If you wish both tests to be available, use a differentnumber for your user test.

7. testing the ICThe test socket is a 24 pin shell with 16 active pins. Insert the IC tobe tested in the front of the 24 pin Zero Insertion Force socket withpin 1 towards the display as shown below:

For 3 pin TO220 or TO92 packages, insert the IC in pins 6, 7 and 8(lower left) of the socket with the metal tab or flat side facing to theright.

Ensure that the operating lever on the socket is in the open (i.e. up)position before inserting the IC. Close the socket by lowering thelever, making sure that the IC is firmly seated in the socket and



making good contact. Press the TEST/EXEC key to activate the testsequence for the IC. If an invalid IC type number was entered, or ifthe IC you have requested is not supported the message "Unknown"will be displayed. Simply entering another IC type number willautomatically clear this error message. If a valid type number wasentered, the IC test will begin and the message "BUSY" will bedisplayed while the test proceeds. Many of the tests, however,execute so quickly that this message is not noticeable.

8. test resultsA pre-determined sequence of signals is applied to the inputs of theIC under test and the output voltages are measured prior tocomparing with the correct values. The exact nature of the testdepends on the function of the IC, but as an example theoperational amplifier tests include both open and closed looptesting over a range of input voltages and gain settings. If all theoutputs respond correctly, the result PASS will be displayed at thetop right of the display. A scroll ing message will contain the ICfunction and power pin information.

If a short circuit between the power pins of the IC is detected, awarning ‘SHT!' wil l appear on the top right of the display and, sinceno valid test is then possible, the result wil l FAIL. If the IC under testtakes an excessive amount of current when power is applied, awarning 'ICC!' wil l appear. Press the TEST/EXEC key to continuewith the test, or MODE/CLEAR to abandon. Depending on thecondition of the batteries there may also be a ‘BAT!’ warning whichindicates that the batteries are incapable of supplying the currentrequired by the IC under test. You can continue with the test bypressing the TEST/EXEC key, but the unit may malfunction becauseof a drop in battery voltage. To avoid this, change the batteries oruse a battery eliminator. Note that a faulty IC may demand moreoperating current and therefore will quickly drain the batteries.

Some ICs require external components to be fitted prior to the test -in these cases the message EXT or CAP will be displayed at the topright of the display. Please refer to the IC lists at the end of this



manual for details of the component(s) required. After fitting thecomponent the test can be carried out by a further press of theTEST key. If you wish you can abandon the test by pressing theCLEAR key.

In the case of a FAIL result, the error conditions at all the non-functional pins of the IC will be scrolled on the display, and the ICfunction will be shown. The various failure conditions that can bedisplayed are as follows:

V<< - the voltage on the pin was lower thanexpected.

V>> - the voltage on the pin was higher than expected.D<< - the diode drop voltage was lower than expected.D>> - the diode drop voltage was higher than expected.LOAD - the input cannot be driven.

In some cases, the scroll ing test results may include one or moreWARNING indications. These warnings indicate conditions that mayresult in an incorrect test result, and are as follows:

D/F - result may be invalid because last self-test failed.BAT - battery voltage too low during testICC - large current taken by IC under test

Some ICs are available in various packages, and also there aresome ICs in the library which have the same numerical part numbereven though the IC functions are different. In these cases the B & KModel 570A will automatically determine the IC type prior to thetest, provided that the IC is functional. If the IC is faulty, thefollowing warning will appear after the test:

WARNING: All Part Types FAIL

This indicates that the IC is faulty, but the pin information cannot bedisplayed since the exact part type cannot be identified.

Before discarding a failed IC check that the correct IC type numberwas entered and also check that the IC pins are clean and makinggood contact with the test socket. Note that there is no way of



stopping a test once it has commenced, but see the description ofloop functions later in this manual.

9. testing further ICsAfter a test is completed, the test result wil l be displayed. To testanother IC of the same type, simply insert the next IC and press theTEST/EXEC key again. To test a different IC, enter the new IC typenumber in the usual way, noticing that pressing the first digit of thenew number automatically clears the previous number from thedisplay. Remember that the MODE/CLEAR key can be used if anerror is made during the entry of the IC type number.

10. continuous testingIt is possible to test the same IC repeatedly to detect intermittent ortemperature-related faults, or to rapidly test a batch of identical ICs.There are three types of test loop modes:

Loop - execute a test repeatedly, regardless of the result.P Loop - execute a test repeatedly, provided the result is PASS.F Loop - execute a test repeatedly, provided the result was

FAIL.

The B & K Model 570A is configured into one of the loop modesusing the MODE/CLEAR key as described earlier. Insert the IC andpress TEST/EXEC in the usual way to start the continuous testprocess. The result of each test is displayed as PASS or FAIL on thetop right of the display. In LOOP mode, this allows a large batch ofidentical ICs to be tested, without any action on the part of theoperator other than inserting the IC. When the IC is inserted,sufficient time must be allowed for the test to take place before theresult status is updated, so if in doubt the IC should be tested insingle mode so that the approximate test time can be determined.It wil l be found that high throughput can be obtained using thismode.

To stop any of the test loops, press MODE/CLEAR, but note that thetest in progress is completed before the command is obeyed. The



effect of this is usually unnoticeable, but where the test takes areasonable time to execute there will be a delay before theinstrument responds to the MODE/CLEAR key.

Note: Testing high current ICs in loop mode will drain thebatteries quickly, and it is recommended that a battery eliminatoris used if you wish to perform loop tests.

11. search modeThis feature allows the type number of an unknown IC to bedetermined, provided the IC is actually contained in the B & KModel 570A library, and it is a correctly functioning IC. This facil ityis useful when the IC type number is il legible or has been removed.

Use the MODE/CLEAR key to choose SEARCH mode, insert theunknown IC into the socket and press the TEST/EXEC key. You willbe prompted to choose the number of pins of the IC you wish toidentify - use the MODE/CLEAR key to select from 3 to 16 pins or'QUIT' to abandon this mode. Press the TEST/EXEC key again tostart the SEARCH or to quit as required.

During the identification process the display will indicate thenumber of ICs identified (IDENT:) and will show graphically how farthrough the library the SEARCH has progressed. At the end of theSEARCH, a list of all the similar ICs will be scrolled onto the display.The list may be scrolled again by pressing the TEST/EXEC key.

If the IC cannot be identified the message "Not in Library" will bedisplayed. This means either that the IC is not in the library or it isnon-functional. Note that if the B & K Model 570A detectsexcessive supply current (ICC! or BAT! warnings), the IC will not beidentified during the SEARCH, but can stil l be tested in SINGLEmode.

If you have a user library present the search will extend to user ICs inthat library also. However, CompactLink contains a facil ity forexcluding ICs from the search if required.



12. self test modeThis feature allows you to check the integrity of the unit, includingthe pin drivers and receivers, power supplies and other internalhardware. The test executes automatically at switch on, but you canif you wish perform a self-test at any time by selecting Self-Test(DIAGS) mode using the MODE/CLEAR key and pressingTEST/EXEC.

If a fault is discovered a brief description will be displayed which willhelp our engineers to locate and rectify the fault. This messageshould be noted and quoted in any correspondence relating to aunit fault. Contact your distributor in the event of a self-test fail, butfirst of all ensure that the socket was empty when the diagnosticswere run.

13. CompactLink modeThe B & K Model 570A is provided with an RS-232 interface toconnect to a PC with a serial COM port or using a USB to RS-232converter. A companion software package CompactLink is availablewhich provides library management, test development anddebugging and user library update facil ities. You can also useCompactLink to update the software of your B & K Model 570Awithout replacing the internal memory or opening the case.

To enter CompactLink mode, user the MODE/CLEAR key to enterCMLINK mode, then press TEST/EXEC. Press TEST/EXEC againto confirm that you wish to enter CompactLink mode, and thedisplay will show “Not Connected”. Run the CompactLink softwareon your PC, connect the serial cable and follow the CompactLinkmanual instructions to connect to the B & K Model 570A.

For comprehensive instructions on using CompactLink please referto the manual and built-in help supplied with the software.

Note that in CompactLink mode, including waiting for a connection,the normal power down timeout is disabled and the unit will remain



on for ever. We recommend using a battery eliminator when usingCompactLink mode to develop test programs.
