Note:
1.
Do not measure the voltage higher than DC 1000V or AC 750V.
2. When measuring the high voltage, caution to avoid electric shock. Cut the connection between
the test lead and tested circuit at once after measurement.
3. At the Manual Range mode, if “OL” is displayed on LCD, it indicates the tested voltage value has
exceeded the present range limit, lease select the higher range to complete the measurement.

1.
Turn the function/range selection knob to ACV.
2.
Insert the red and black test lead separately to V
Ω
Hz and VCOM input terminal, displayed as the
right picture.
3.
The instrument was preset as the Auto Range mode, displays “AUTO” symbol on LCD, press
“RANGE” button to switch to the Manual Range mode. ACVmV only can be operated under “RANGR”.
Press “Hz/DUTY” button to measure Frequency/Duty Circle at the Auto Range or Manual ACA model,
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,
38V/50Hz-400Hz.
4.
Connect the test lead to the tested circuit in parallel, the polarity of the red test lead and the
tested voltage value will be displayed on LCD simultaneously.
Note:
1.
Do not measure the voltage higher then DC 1000V or AC 750V.
2.
When measuring the high voltage, caution to avoid electric shock. Cut the connection between
the test lead and tested circuit at once after measurement.
