OPERATION 
77 
The Interlock function is a safety feature. The 
interlock function prevents a test from running, 
unless the interlock pins on the signal I/O port 
connector are shorted. The included interlock 
key can be used for this purpose. See page 102 
for details. 
1.  Ensure the tester is in VIEW status. 
Save the current test if necessary.
