2. Set the rotary switch to an appropriate measurement position in
3. Connect the test leads across with the object being measured.
The measured value shows on the display.
Note
•
If the value of voltage to be measured is unknown, use the maximum measurement position
(1000V) and reduce the range step by step until a satisfactory reading is obtained.
•
The LCD displays "1" indicating the existing selected range is overloaded, it is required to
select a higher range in order to obtain a correct reading.
Warning!
To avoid harms to your or damages to the Meter from electric shock, please do not attempt to
measure voltages higher than 1000V or 750V rms although readings may be obtained.
Take extra attention when measuring high voltages to avoid electric shock.
To measure DC voltages, connect the Meter as follows:
1. Insert the red test lead into the
input terminal.
2. Set the rotary switch to an appropriate measurement position in
3. Connect the test leads across with the object being measured.
The measured value shows on the display, which is effective value of sine wave (mean value
response).

•
In each range, the Meter has an input impedance of approx. 10M . This loading effect can
cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal
to 10K , the error is negligible (0,1% or less).
•
When AC voltage measurement has been completed, disconnect the connection between
the testing leads and the circuit under test.
