Functionality
The current, voltage and power average and peak measurement functions CMSTA,
VMSTA and PEMSTA are used to calculate the average and peak value of current,
voltage and power. The functions can be enabled and disabled with the Operation
setting.
The corresponding parameter values are "On" and "Off". The average interval can be
set to "3","10", "15", "60", "120", or "1440" minutes and the peak interval to "1 day",
"1 week", "1 month", or "1 year".
