5.2 Voltage, frequency and phase sequence
Voltage and frequency measurement is always active in the terminal voltage monitor. In
the special VOLTAGE TRMS menu the measured voltage, frequency and information
about detected three-phase connection can be stored. Measurements are based on the
BS EN 61557-7 standard.
See chapter 4.2 Function selection for instructions
on key functionality.
