MAinS.F – Select Line Frequency
Selection of the measuring signal line frequency is required for the
calculation of the TRMS half-cycle value:
mains .f set : 50 /60 Hz

MAinS rAnGE – Select a Measuring Range for Mains Disturbance
Recording
Mains disturbance recording takes place within the specified, fixed
measuring range. Exception: Event type +/–trAnS is always detec-
ted within the 200 to 1000 V range.
range set : 6 . 0000/60 . 000/600 .00 V

LoVolt and HiVolt – Trigger Thresholds
You can specify the limits within which AC+DC TRMS voltage must
lie in the following two displays. If these limits are exceeded or fal-
len short of, a HiVolt or a LoVolt event is recorded.
These limits are specified in digits independent of range, and
60,000 digits correspond to the full measuring range span.
lovolt limit : 00 000 ... .60 000 Digit

hivolt limit : 00 000 ... .60 000 Digit 
SwELL and diP Limit – Trigger Thresholds for Brief Overvoltages and
Undervoltages
A TRMS half-cycle value is calculated for each of the signal’s half-
cycles. If this value is less than the selected lower limit (diP Limit) or
greater than the upper limit (SwELL Limit), a dip or swell event is
recorded.
The entry is made in digits, and 60,000 digits correspond to the full
measuring range span.
