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
