Alarm

Alarms are of two types: PV range alarm group (alarm code number 01 to 04) and instrument alarm group (alarm code number 91 to 99 and battery voltage drop). When the event type is all alarm, the event goes on if one alarm occurs. When the event type is a PV range alarm, the event goes on if one alarm in the PV range alarm group goes on.

When the event type is an instrument alarm, the event goes on if one alarm in the instrument alarm group goes on.

ADV

When ADV (advance) is executed, the event goes on for 1 second. This function is valid during on delay.
