Event History
If the EMM54 is equipped with a data logger (option –DM), it’s possible to store occurring alarms with time stamp.
The event recorder consists of 64 memory cells. Each event (occurrence and drop out the alarm) is stored in a
separate memory cell. Are all storage cells full, the recording starts again at memory cell one. As additional
information will be stored the values listed in the following table.
