6.9 Non-Contact Voltage Detector
Warning: For safety, always test the voltage detector on a known live circuit before
using the voltage detector on unknown voltage potentials.
1. Set switch to the NCV
position. See Figure 6-3.
2. Be sure to remove the test leads from the meter.
3. Short press the RANGE button to toggle the Hi (20~1000V) and Lo (80~1000V)
sensitivity modes.
4. Position the top of the meter close to a source of voltage.
5. When the meter detects a voltage, it beeps and displays a blue bar animation. The
tone rate and the bar number will increase relative to the detected voltage.
