Interlock signal
The interlock is the function to shut off the output getting the tester to jointly work with
the external device, in order to secure the safety of operator.
By making open the pin 5 (INTER-LOCK) of the
REMOTE/OUT
connector
⑱
on the
rear panel, the tester becomes interlock status and the start of the test is disabled.
During the interlock function is in operation,
is displayed, the output of
8526
is shut off and the operation of all the switches are disabled.
To cancel the interlock, short-circuit the pin 5 and pin 23 (COM) of the
REMOTE/OUT
connector
