normal voltage range 360V ~
420V. If the voltage fluctuation is
large, it is recommended to use
the correct voltage source and

The AC gear of the multimeter
measures the input value of the
servo LN (R/S/T), which is 220V
± 10% of the normal value. If the
power supply voltage is more
than 220V+10% (380V+10%),
