5.9.1 Non-contact phase testing
There is a detector located on the top of the device. This detector enables non-contact detection
of alternating fields.
Requirements
• Please observe the requirements for measuring [

page 26].
• Make sure that no voltage is applied to the jacks of the device (“COM” and “+”). Remove
any connected safety measuring lines.
Figure 14: Non-contact phase testing
Procedure
1. Set the rotary switch of the device to switch position “Volt Sense / Lo‑Z Auto‑V”.
2. Press the “AC HFR / DCA ZERO” key to enable the “Voltage indicator” function.
“EF” is shown on the digital display.
3. Place the top of the measuring clamp near the measuring point.
If the symbols “ ” and “EF” are flashing on the digital display, the phase of an earthed
alternating voltage is applied to this measuring area.
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
