Chapter 7: Logging Data - GE PM880 Operations & Installation Manual

Logging Data
A powerful and flexible feature of the PM880 is data logging.
The meter enables you to choose up to 12 parameters to log. You
can also select the start time and date, end time and date, and time
interval. Logs can run one at a time or simultaneously. Error and
circular logs are also available. The logged data is internally
stored in battery-backed-up memory. A fixed amount of memory
is assigned to data logging. The frequency of the time interval,
the length of the log run, and the number of logs affect the
amount of memory required for a particular log. For example, a
log that records every 5 seconds will use up more memory than a
log that records every 5 minutes for a given amount of time. Once
you make your data logging selections, the PM880 enables you to
view the amount of memory left. You may also stop logging or
view logged data while or after data is logged.
