To determine the mains frequency, the device
requires a voltage of >20 V
eff
(4-conductor mea-
surement) or an L1-L2 voltage of >34 V
eff
(3-con-
ductor measurement) at voltage measuring input
V1.
NOTE
Devices with the setting
Auto
take about 5 sec-
onds to determine the mains frequency. During
this time, the measured values
do not
maintain
the guaranteed measurement uncertainty.
NOTE
If the mains frequency is outside the range of 45-
65 Hz:
·There is no error or warning alert.
·When a constant frequency (
50/60 Hz
) is indi-
cated, the corresponding setting is used.
·When automatic frequency detection is select-
ed (
Auto
), the last determined frequency in the
range of 45-65 Hz is used.
The determination of the frequency runs over a
period of 10 seconds. The frequency does
not
represent a 200 ms measured value!
