dEMAnd tiME – Time Interval for Mean Value Generation (parameter for
power measurement in memory mode)
The dEMAnd tiME parameter specifies the length of the time
period during which measured power is averaged for the display of
a mean power value (see section 5.7 on page 47).

EnErGY StorE – Scope of Stored Values for Power and Energy
Measurements
The StorE parameter (mode) can be used to specify which values
will be saved to memory during power and energy measurements
when memory mode operation is active. There are three possibili-
ties:
• Normal (default setting): Momentary values for current, voltage, ac-
tive, reactive and apparent power, as well as power factor, are
acquired and saved to memory at the selected sampling rate
(rAtE parameter, at least 0.5 s).
• Demand: Mean power values for active, reactive and apparent
power are saved to memory at the end of each observation pe-
riod as specified with the dEMAnd tiME parameter.
• All: Momentary values are saved at the selected sampling rate and
mean power values are saved at the end of each observation pe-
riod.
