Note:
a) Do not measure the voltage higher than DC 1000V or AC 750V.
b) When measuring the high voltage, caution to avoid electric shock.
Cut the connection between the test lead and tested circuit at once
after measurement.
C) At the Manual Range mode, if “OL” is displayed on LCD, it
indicates the tested voltage value has exceeded the present range
limit, please select the higher range to complete the measurement

AC Voltage (ACV)
1. Turn the function/range selection knob to ACV/DCV, press
“SELECT” button to switch to ACV measurement mode. Insert the
red and black test lead separately to VΩHz and COM input terminal,
displayed as the following picture.
2. The instrument was preset as the Auto Range mode, displays
“AUTO” symbol on LCD, press “RANGE” button to switch to the
Manual Range mode. Press “Hz/DUTY” button to measure
Frequency/Duty Circle at the Auto Range or Manual Range mode.
But the frequency response is very low, at this time, it suits to
measure the circuit of high voltage and low frequency under the
circumstance of magnetic disturbance, such as
220V/50Hz-400Hz,380V/50Hz~400Hz.
3. Connect the test lead to the tested circuit in parallel,the polarity of
