Mains power supply voltage is displayed on the LCD. Please check the value,
and when it is from 207V to 253V, the instrument can perform correct
measurements. If the displayed value is out of above range, do not make a
measurement.
WARNING
● When the voltage of mains power supply is 260V or more, "HI-V" is
displayed on the LCD and buzzer sounds (discontinuous sounds). In that
case, disconnect the mains cord of the instrument from mains power supply.
