Model 570A Linear IC Tester

1. introduction

Thank you for purchasing the B & K

Precision Model 570A Hand Held

Linear IC Tester.

The basic function of the B & K Model

570A Linear IC Tester is to test a linear

IC for correct logical functioning as

described in the manufacturer’s IC data

sheets. The B & K Model 570A applies the necessary analogue

signals to the inputs of the IC, monitoring the outputs at each stage

and comparing them with the expected voltages. Any discrepancy

results in a FAIL indication and the faulty pins are shown on the

integral display. Additional facilities are also provided, amongst

them test loops that can be used for goods inwards inspection,

detecting intermittent faults or simply providing a rapid method of

exercising any IC for demonstration or educational purposes. Since

the B & K Model 570A contains an extensive IC library, it is not

necessary to program the unit yourself other than to key in the IC

number. It is also capable of identifying an unknown IC using the

SEARCH mode - this is a feature that many users will find extremely

valuable.

The B & K Model 570A is provided with an RS-232 interface

enabling it to be connected to a companion software package

called CompactLink running on a PC. CompactLink allows test

programs for ICs not included in the internal library to be developed

and downloaded into the B & K Model 570A memory to enhance

the library according to your wishes.

2. DC input

The B & K Model 570A is powered by four AA batteries or by the

use of the battery eliminator input at the rear of the case. To insert

the batteries, turn the unit upside down and remove the battery

Model 570A Linear IC Tester

cover by removing the two cross head screws holding it in place.

The batteries must be inserted in the correct orientation, as

indicated by the drawing within the battery compartment. Incorrect

insertion of batteries will not allow the unit to operate. Replace the

battery cover and insert the screws. If the battery voltage falls too

low, a low battery warning symbol will be displayed at the top left

hand cell of the display in normal operating mode. A low battery

warning will also be displayed during a result display. Test results

may be inconsistent under these conditions.

3. battery eliminator

An external battery eliminator is available for prolonged use of the

B & K Model 570A. Some ICs consume a significant amount of

current when powered up, and battery life can be conserved by

using the eliminator. There is no need to remove the batteries prior

to inserting the battery eliminator. However, please note that during

prolonged periods of non-use batteries are prone to leakage and

should be removed. Note that to avoid damage to the unit we

strongly advise that you only use the recommended battery

eliminator that is available by contacting your distributor. Note that

using an incorrect battery eliminator voltage may damage the unit

and invalidate the warranty.

4. switching on

To switch the unit on, simply press the 'ON' key. To preserve battery

life, the unit powers itself off after approximately three minutes of

non-use or when “Sw Off” is selected from the main menu. When

the unit is switched on, it first performs a self-diagnosis test.

Therefore, before switching on, check that the test socket is empty to

prevent interference with the diagnostics. If the unit passes the self-

test, a pass result will be displayed on the screen. Press a key to

enter the main operating mode - the display will be as follows:

NO:

MODE:Single :RDY

Model 570A Linear IC Tester

When this initial display is obtained the B & K Model 570A is ready

for use. If, however, the message SELF-TEST FAIL: is displayed

along with a fault message, this indicates that a self-test diagnostic

fault has been detected. Any detected faults will be displayed one

at a time. Pressing the TEST/EXEC key will then revert to the

opening menu as above, but of course operation of the unit will

then be suspect. Before contacting your distributor, check that the

test socket is completely empty.

5. operating modes

The B & K Model 570A has a number of test modes that are

selected using the MODE/CLEAR key from the initial screen. The

test 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 numbers

Press the MODE/CLEAR key until the desired test mode is displayed.

Enter the number of the IC you wish to test. Pressing the

MODE/CLEAR key will clear the last digit from the display if a

mistake is made.

Note: The NUMERIC information only is entered, leav ing out the

manufacturers prefixes and suffixes and IC family information.

As an example, all the following linear ICs should be entered as

7, 4, 1 on the keypad:

e.g. uA741CP, uA741M, uA741C etc

Model 570A Linear IC Tester

Some ICs are available in different pin outs or package types, and

also there may be several different types of IC with the same

numerical part number. In these cases the B & K Model 570A will

automatically determine which test to perform. If however the IC is

faulty the unit may not be able to determine the correct IC type - if

this happens a warning message will be displayed. A complete list

of all ICs supported by the B & K Model 570A is contained in the IC

SUPPORT LIST at the end of this manual together with notes on

any special requirements for certain ICs.

Note that if you have stored a user library using CompactLink, an IC

in the user library with the same number as one in the internal

library will take precedence. This allows a new test to be written for

an existing IC. If you wish both tests to be available, use a different

number for your user test.

7. testing the IC

The test socket is a 24 pin shell with 16 active pins. Insert the IC to

be tested in the front of the 24 pin Zero Insertion Force socket with

pin 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 the

right.

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 the

lever, making sure that the IC is firmly seated in the socket and



Model 570A Linear IC Tester

making good contact. Press the TEST/EXEC key to activate the test

sequence for the IC. If an invalid IC type number was entered, or if

the IC you have requested is not supported the message "Unknown"

will be displayed. Simply entering another IC type number will

automatically clear this error message. If a valid type number was

entered, the IC test will begin and the message "BUSY" will be

displayed while the test proceeds. Many of the tests, however,

execute so quickly that this message is not noticeable.

8. test results

A pre-determined sequence of signals is applied to the inputs of the

IC under test and the output voltages are measured prior to

comparing with the correct values. The exact nature of the test

depends on the function of the IC, but as an example the

operational amplifier tests include both open and closed loop

testing over a range of input voltages and gain settings. If all the

outputs respond correctly, the result PASS will be displayed at the

top right of the display. A scrolling message will contain the IC

function and power pin information.

If a short circuit between the power pins of the IC is detected, a

warning ‘SHT!' will appear on the top right of the display and, since

no valid test is then possible, the result will FAIL. If the IC under test

takes an excessive amount of current when power is applied, a

warning 'ICC!' will appear. Press the TEST/EXEC key to continue

with the test, or MODE/CLEAR to abandon. Depending on the

condition of the batteries there may also be a ‘BAT!’ warning which

indicates that the batteries are incapable of supplying the current

required by the IC under test. You can continue with the test by

pressing the TEST/EXEC key, but the unit may malfunction because

of a drop in battery voltage. To avoid this, change the batteries or

use a battery eliminator. Note that a faulty IC may demand more

operating 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 top

right of the display. Please refer to the IC lists at the end of this

Model 570A Linear IC Tester

manual for details of the component(s) required. After fitting the

component the test can be carried out by a further press of the

TEST key. If you wish you can abandon the test by pressing the

CLEAR 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 IC

function will be shown. The various failure conditions that can be

displayed are as follows:

V<< - the voltage on the pin was lower than

expected.

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 scrolling test results may include one or more

WARNING indications. These warnings indicate conditions that may

result 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 test

ICC - large current taken by IC under test

Some ICs are available in various packages, and also there are

some ICs in the library which have the same numerical part number

even though the IC functions are different. In these cases the B & K

Model 570A will automatically determine the IC type prior to the

test, provided that the IC is functional. If the IC is faulty, the

following warning will appear after the test:

WARNING: All Part Types FAIL

This indicates that the IC is faulty, but the pin information cannot be

displayed since the exact part type cannot be identified.

Before discarding a failed IC check that the correct IC type number

was entered and also check that the IC pins are clean and making

good contact with the test socket. Note that there is no way of

Model 570A Linear IC Tester

stopping a test once it has commenced, but see the description of

loop functions later in this manual.

9. testing further ICs

After a test is completed, the test result will be displayed. To test

another IC of the same type, simply insert the next IC and press the

TEST/EXEC key again. To test a different IC, enter the new IC type

number in the usual way, noticing that pressing the first digit of the

new number automatically clears the previous number from the

display. Remember that the MODE/CLEAR key can be used if an

error is made during the entry of the IC type number.

10. continuous testing

It is possible to test the same IC repeatedly to detect intermittent or

temperature-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 modes

using the MODE/CLEAR key as described earlier. Insert the IC and

press TEST/EXEC in the usual way to start the continuous test

process. The result of each test is displayed as PASS or FAIL on the

top right of the display. In LOOP mode, this allows a large batch of

identical ICs to be tested, without any action on the part of the

operator other than inserting the IC. When the IC is inserted,

sufficient time must be allowed for the test to take place before the

result status is updated, so if in doubt the IC should be tested in

single mode so that the approximate test time can be determined.

It will be found that high throughput can be obtained using this

mode.

To stop any of the test loops, press MODE/CLEAR, but note that the

test in progress is completed before the command is obeyed. The

Model 570A Linear IC Tester

effect of this is usually unnoticeable, but where the test takes a

reasonable time to execute there will be a delay before the

instrument responds to the MODE/CLEAR key.

Note: Testing high current ICs in loop mode will drain the

batteries quickly, and it is recommended that a battery eliminator

is used if you wish to perform loop tests.

11. search mode

This feature allows the type number of an unknown IC to be

determined, provided the IC is actually contained in the B & K

Model 570A library, and it is a correctly functioning IC. This facility

is useful when the IC type number is illegible or has been removed.

Use the MODE/CLEAR key to choose SEARCH mode, insert the

unknown IC into the socket and press the TEST/EXEC key. You will

be prompted to choose the number of pins of the IC you wish to

identify - use the MODE/CLEAR key to select from 3 to 16 pins or

'QUIT' to abandon this mode. Press the TEST/EXEC key again to

start the SEARCH or to quit as required.

During the identification process the display will indicate the

number of ICs identified (IDENT:) and will show graphically how far

through the library the SEARCH has progressed. At the end of the

SEARCH, 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 be

displayed. This means either that the IC is not in the library or it is

non-functional. Note that if the B & K Model 570A detects

excessive supply current (ICC! or BAT! warnings), the IC will not be

identified during the SEARCH, but can still be tested in SINGLE

mode.

If you have a user library present the search will extend to user ICs in

that library also. However, CompactLink contains a facility for

excluding ICs from the search if required.

Model 570A Linear IC Tester

12. self test mode

This feature allows you to check the integrity of the unit, including

the pin drivers and receivers, power supplies and other internal

hardware. The test executes automatically at switch on, but you can

if you wish perform a self-test at any time by selecting Self-Test

(DIAGS) mode using the MODE/CLEAR key and pressing

TEST/EXEC.

If a fault is discovered a brief description will be displayed which will

help our engineers to locate and rectify the fault. This message

should be noted and quoted in any correspondence relating to a

unit fault. Contact your distributor in the event of a self-test fail, but

first of all ensure that the socket was empty when the diagnostics

were run.

13. CompactLink mode

The B & K Model 570A is provided with an RS-232 interface to

connect to a PC with a serial COM port or using a USB to RS-232

converter. A companion software package CompactLink is available

which provides library management, test development and

debugging and user library update facilities. You can also use

CompactLink to update the software of your B & K Model 570A

without replacing the internal memory or opening the case.

To enter CompactLink mode, user the MODE/CLEAR key to enter

CMLINK mode, then press TEST/EXEC. Press TEST/EXEC again

to confirm that you wish to enter CompactLink mode, and the

display will show “Not Connected”. Run the CompactLink software

on your PC, connect the serial cable and follow the CompactLink

manual instructions to connect to the B & K Model 570A.

For comprehensive instructions on using CompactLink please refer

to 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

Model 570A Linear IC Tester

on for ever. We recommend using a battery eliminator when using

CompactLink mode to develop test programs.
