Description
Record size
Shows the size of the file record for a single
channel or section. It is set automatically
depending on the file and on the number of
parameters in the data record
Parameters
Defines the number of parameters in a single
data record for data log files.
Memory is allocated for each file statically when you set up the files and
will not change unless you re-organize your files.
The following table shows how to calculate a file size for different log files.

Event Recording
By default, the meter stores to the Event Log file all events related to
configuration changes, resets, and device diagnostics.
In addition, the meter can record to the Event Log events related to
setpoint operations. To record setpoint operations to the Event Log, add
the “Event log” action to the setpoint actions list. When a setpoint event
happens, the meter records all setpoint conditions that caused the event
and all setpoint actions performed in response to the event.
Data Recording
The data recorder is event-driven and can be triggered by any event
through the programmable setpoints.
