User Manual

Note:

• AC V (and hence DC+AC V and Hz) function is equipped with digital

low-pass filter, and is capable of dealing with VFD (Variable Frequency

Drives) signals. It also improves AC V reading stability in noisy electrical

environments.

Voltage Detection (NCV)

Non-Contact Voltage Detection:

1. Turn the rotary switch to

NCV (EF). Press SELECT button to toggle

NCV (EF) mode (“EF” is displayed).

2. The voltage detection antenna

is located along the top-right

end of the stationary clamp jaw for detecting electric field surrounds

energized conductors

3. Detected electric field signal strength is indicated by a series of bar-

graph segments on the display and beeper. The stronger the electric

field detected, the more bar-graph segments are displayed and more

intense beep sounds.
