MEASUREMENT OPERATION
Below section explains how to make measurements.
Press and hold ON/OFF to turn on the Meter, press again to turn off the Meter. The Meter default
range is 500V insulation resistance continuous measurement when turning on.
A.Measuring Voltages
CO M V
� OPERATING CAUTION!
• To avoid harms to you or damages to the Meter, please do not attempt to measure voltages
higher than 600V or 600V rms, although readings may be obtained.
• Special care should be taken when measuring high voltage.
To measure voltages, set up the Meter as Figure 4 and do the following:
1. Press DCV or ACV button to select DC voltage or AC voltage measurement
2. Insert the red and green test lead into the tested circuit.
3. When measuring DC voltage, if the red test lead is negative voltage, м-м symbol will show on
the display.
Note
• When voltage measurement has been completed, disconnect the connection between the
testing leads
and the circuit under test and remove testing leads away from the input terminals of the
Meter.
