Power measurement
Method

Direct read method: Directly read the
measurement value measured from power
measuring instrument.

The average power method: Record the actual
power value within a settable period of time
and then take the average. A settable period of
time isn’t less than 10min. The maximum
measurement interval is one second.

Energy accumulation method: Measure the
energy within a settable period of time and
then divide it by the time to get the power. A
settable period of time isn’t less than 10min.
The cumulative energy must be greater than the
resolution by 200 times.
Measurement for small current
Voltage measurement mode measured from power supply side
(Connect to ammeter internally). The current measurement is
accurate. The voltage measurement on load could be larger than
the actual one due to partial pressure of multi-measurement
ammeter.
