b) DC/AC voltage Measurement
The input impedance is approximate-
ly 10 MΩ and will not put much strain
on the circuit.
1. Set the function dial to the required setting:
• DC voltage measurement (V ), “DC” will
show on the display.
• AC voltage measurement (V ), “AC” will
show on the display.
2. Connect the test leads to the terminals:
- Red test lead to the
terminal.
- Black test lead to the COM terminal.
3. Connect the test lead probes to the correct
test points in the circuit:
- Red: Positive polarity “+”.
- Black: Negative polarity “-”.
4. Read the voltage values on the display.
- DC voltage measurements (V ): If a minus “-” sign appears in front of the value, the
measured voltage is negative (or the measuring lines are swapped).
A warning will sound when measured values are out of range >600 V.
5. When finished measuring, disconnect the test leads and switch the power OFF.
