Model 570ALinear 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 isto 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 outputsat 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 isa feature that many userswill 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 ICsnot 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

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 isno need to remove the batteriesprior
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 pressthe '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, checkthat the test socket isempty to
prevent interference with the diagnostics. If the unit passes the self­test, 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

When this initial display is obtained the B & K Model 570A isready
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 faultswill 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 iscompletely 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 modesare asfollows:

Single - execute a single test on the IC in the socket.
Loop - execute test repeatedly, regardlessof 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 CompactLinksoftware.
Sw Off - turn off the unit

6. entering test numbers

Pressthe MODE/CLEAR key until the desired test mode isdisplayed.
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, leaving 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
