manual together with notes on any special requirementsfor 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. Thisallows 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

Insert the IC to be tested in the front of the 40 pin Zero Insertion

Force socket with pin 1 towards the display as shown below:

Ensure that the operating lever on the socket isin 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

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 isnot 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 thismessage isnot noticeable.
