3. For your convenience, PAS follows your selection and
helps you configure a series of the neighboring
parameters: when you open the “Group” box for the
next parameter, PAS highlights the same group as in
your previous selection; if you select this group again,
PAS automatically updates the “Parameter” box with
the following parameter in the group.
4. Add the name for your data log file in the “Name” box.
It will appear in the data log reports.
5. Save your new setup to the device database, and send
it to the meter.
Factory Preset Data Log Files
Conventional Data Logs
Data log #1 and Data log #2 are factory preset for 15-min
periodic recording of the standard power quantities. You can
freely change the list of recorded parameters and the update
rate for both files.
Periodic recording data to these files is triggered by Setpoint
#1 that is linked to the meter clock. To change the periodic
rate at which data is recorded, change the time interval for
the MINUTE INTERVAL trigger in Setpoint #1 (See
Using
Control Setpoints in Chapter 5).
Data Log #1
Data Log #1 is configured for recording 1-second phase
voltages, currents total harmonics, and total powers. The list
of parameters is shown in the following table.

Data Log #2
Data Log #2 is configured for recording present voltage,
current and power demands, engineering (not billing) energy
counters, and 1-second neutral current and line frequency.
The list of parameters is shown in the following table.
