3. Non-Contact Electric Field Measurement and Setting (Figure 6)
If you need to measure whether there is an AC voltage in the space, please select the NCV function
and keep the NCV antenna at the front end of the instrument clamp head close to the measured
object at a distance of about 8-15mm for induction detection. If the induced voltage is less than 90V,
EF will be displayed, and if the induced voltage is greater than 90V, "-" will be displayed; four
segments (“- - - -”) are set according to voltage and there are beeps in different rhythms in different
segments, accompanied by a flicker of the NCV indicator to distinguish the intensity of the induced
voltage.
When the function is switched to NCV, please remove the test probe to avoid electric shock.
