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
