Hold: During the power-on sequence, the alarm output is kept OFF (disabled) even when
the monitored quantity is within the alarm range. Once it goes out of the alarm range,
and comes into the alarm range again, the alarm is enabled.
Latch: Once the monitored quantity comes into the alarm range and the alarm is turned ON,
the alarm will remain ON even if it goes out of the alarm range. To release the latch,
perform a reset by using the key or turning the terminal command
RST ON.
Resetting can be done by the same way as resetting an alarm.
