Loz Ac Voltage Measurement - VOLTCRAFT VC191 Bedienungsanleitung

c) LoZ AC voltage measurement
The LoZ measuring function permits alternating "AC" voltage measurements with low imped-
ance (approx. 3 kΩ). The lower internal resistance of the meter reduces measurement discrep-
ancies such as phantom voltages.
The input impedance is approximately 3 kΩ and will put some strain on the circuit.
1. Set the function dial to LoZ V .
2. Connect the test leads to the terminals:
- Red test lead to the
- 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.
- The displayed value is true RMS.
- Wait for 3 minutes before next operation.
5. When finished measuring, disconnect the test
leads and switch the power OFF.
