Procedure
Turning ON inhibit and selecting the polarity
Press the INH key to select
or
. The indicator of the selected item lights and
inhibit is turned ON.
Turning OFF inhibit
Press the INH key to turn OFF both the
and
indicators. Inhibit is turned OFF.
Explanation
You can inhibit measurements by applying an external signal (inhibit signal) to the
INHIBIT input connector. This is possible even while the gate is open or during
measurement after arming activation.
Selecting the polarity
•
: Inhibits measurements while a positive signal is being input.
•
: Inhibits measurements while a negative signal is being input.
Inhibit signal
Input the inhibit signal to the connector indicated as “INHIBIT” on the rear panel.
