NCV Test
1. Have the rotary switch in any position, press the
button for
more than 2 seconds, the device will make a “click” sound and
show “NCV” in the display.
2. Gradually approach the voltage source with the NCV probe,
which sits on top of the device.
3. When the meter senses weak AC signals and the display
shows “---L”, while the buzzer sends out slow-paced acoustic
signals.
4. When the meter senses strong AC signals and the display
shows “---H”, while the buzzer sends out fast-paced acoustic
signals.
WARNING:
•
Do not measure voltage above 600V; otherwise the
instrument might get damaged.
•
Remove all probes from the input sockets.
•
Pay special attention to safety when measuring high
voltage to avoid electric shock or personal injury.
•
The NCV test is only a first indication and cannot replace
voltage measuring.
