• AC Voltage Measurement
Do not measure voltage higher
than 500V. It may make damage
to internal circuit. If the voltage is
over 750 VAC, the beeper will
sound for warning continuously,
designating an over-range
measurement.
1.Set the function/range switch to
the appropriate AC voltage range.
2.Measure the voltage by touching
the probes to the desired test
points of the circuit. With AC
voltage, the polarity of the test
leads is not a factor.
3.Read the
measured
voltage on
the display.
