Protection Settings
The Protection settings are used to prevent damage to the unit or
the DUT by excessive current, voltage or power.
An alarm is generated and a message is displayed on the screen
when a protection setting is tripped. When an alarm is activated,
the load is turned off (or limited), and the ALARM STATUS pin of
the J1 connector on the rear panel (pin 16) turns on (open collector
output by a photocoupler). The protection settings can be used
regardless of whether the remote sense connections are used or not.
