Mains frequency (Addr. 034)
For automatic ascertainment of the mains frequency, an
L1-N voltage larger than 10Veff must be applied to the
voltage measurement input V1.
The sampling frequency is computed for the current
and voltage inputs based on the mains frequency.
If the test voltage is missing, neither the network
nor the sampling frequency can be computed.
An acknowledgeable error message "500" will
be displayed.
Voltage, current and all resulting values are calculated
and displayed based on the most recent frequency
measurement and/or possible power couplings.
The measured values that have been determined can
no longer guarantee the declared precision.
When another measurement of frequency can be carried
out, the error message will automatically disappear
in about 5 seconds after the voltage returns.
The error is not displayed when a fixed frequency is set.
Setting range: 0, 45 .. 65
0 = automatic frequency determination.
The mains frequency is determined based
on the measurement voltage.
45..65 = fixed frequency
The mains frequency is pre-selected as a fixed value.
