tested voltage value has exceeded the present range limit, please select
the higher range to complete the measurement.
2. Do not measure the voltage higher than 600V. Otherwise, there is the
danger to damage the instrument.
3. When measuring the high voltage, caution to avoid the body touches the
high voltage.
