Procedure
1. Set the rotary switch of the device to switch position “V‑AC”.
2. Press the “VoltSense” key to enable the “Voltage indicator” function.
“EF‑H” appears on the digital display (electric field with high sensitivity).
If necessary, you can reduce the sensitivity by pressing the “VoltSense” key again. “EF‑L”
appears on the digital display (electric field with low sensitivity).
3. Place the top right of the device near the measuring point.
If the device detects the phase of an earthed AC voltage, the symbol “EF‑H” or “EF‑L” will
disappear. A bargraph indication and an acoustic signal indicate the strength of the electric
field.
Practical tip
Interruptions (cable breaks) in exposed cables – e. g. in cable reels, chains of light, etc. – can
be traced from the feeding point (phase) to the point of interruption.
Functional range: ≥230 V
