For example, consider the following capture:

PT primary = 13.8 kV

PT secondary = 120V

CT primary = 100 A

CT secondary = 5 A

Delta voltage mode (line-to-line)

You would multiply each data point by the following factor to
correctly display the waveform:

Capture Statistics

The Capture timestamp and Capture identifier are important statistics
that identify the capture. A data client may use the Capture identifier
to associate the transient capture with corresponding metering data
and event log data.

Clear Command

Issue the Clear command parameter to clear transient captures from
non-volatile memory and provide space for new captures. Write the
correct Password for the power monitor to accept the command. The
command parameter options include the following:

-1 - Clear all transient captures
0 - No action
1 - Clear capture #1
2 - Clear capture #2
3 - Clear capture #3
4 - Clear capture #4
5 - Clear capture #5
6 - Clear capture #6

At least one capture location must be clear for a transient detect event
to be processed. If no captures are clear, the power monitor ignores
any new transient detection events.
