Alarm Output Latching
When an alarm is triggered, the output will be disabled with the exception
of the Fan alarm. When an alarm is cleared, the alarm output latch
determines if the output should be re-enabled to the state before the alarm
occurred or if the output should remain in the off state.
The output latches are accessible through the SCPI command.
The SCPI command (s) for these instructions are:
[:]SYSTem[<channel>]:PROTection:LATCh
The latch command take a single decimal parameter made up of the sum
of the values for the alarms to determine if they are to be latched in the off
state on clearing. See Table 3-6 for the values associated with each
latchable alarm.
