10.1 General
Calibration Due to Internal Requirements
The device comes calibrated from the factory and does not have to be calibrated again throughout its entire
operation period. The calibration is only carried out if this is necessary due to internal requirements.
Calibration Device
To test the SICAM MMU, a calibration device is necessary that generates the alternating voltages, alternating
currents and phase angles with a tolerance of max. 0.1 % of the rated value that is fed in.
If the testing devices are galvanically separated, you have to connect the terminal N to the protective grounding
terminal at terminal block F - Voltage.
NOTE
Measured values are entered or displayed with a decimal point separating the integral and the fractional parts,
for example 400.34 V.
NOTE
You have to observe the specifications and execution instructions of the accident prevention regulation
BGV A3. Use appropriate electric tools.
