Use current clamp transformers
only. Power measurement is not
possible with current clamp sen-
sors equipped with voltage out-
put.
Note:
See also section 4.5.2, "Power
and Energy Measurement in the
Memory Mode”.
Min-Max Function in Power Measurement
Instantaneous power is displayed with the switch in the W setting.
The Min-Max function is activated with the DATA/MIN/MAX key. The
minimum and maximum values for active, reactive an apparent
power are display as of the beginning of the power measurement,
along with time of occurrence (date and time). Previous Min-Max
values can be cleared without exiting the function by pressing the
ZERO key.
This function differs from the general Min-Max function insofar as
measurement is performed continuously in the background, even if
the Min-Max display is not shown, and while the instrument is in
the energy measuring mode.
