Power direction
This parameter allows you to set the operating mode of the SICAM P:
•
Load (industry mode, standard)
this means:Power positive = Energy demand
•
Generator (Power generation mode)
this means:Power negative = Energy demand
Counter assignment
Internal counters 1 to 4 can be displayed in the digital measured value screens of the SICAM P.
You can assign the four internal counters to the max. 6 limit values groups here.
Zero point suppression
The zero suppression enables the definition of the measuring range start in % of the measuring
range end. Can be selected from 0.0 % to 10.0 % of the upper limit of the measurement range
(default setting: 1.000 %).
Note
Due to its high precision, SICAM P can measure voltages and currents even without measuring
values connected to the device. If you do not want this behaviour in your application, you can
suppress measuring below a certain threshold.
