Electric Field EF-Detection
Press the EF button momentarily to toggle EF-Detection feature. The meter displays “EF-H”
when it is ready. If it is too sensitive for your applications, press (Level) button momentarily
toggles to lower sensitivity “EF-L”. The detected Electric Field strength is indicated as a
series of bar-graph segments on the display plus variable beep tones.
●Non-Contact EF-Detection: An antenna is located along the top-left end of the meter,
which detects electric field surrounding energized live conductors. It is ideal for tracing live
wiring connections, locating wiring breakages and to distinguish between live and earth
connections.
●Probe-Contact EF-Detection: For more precise indication of live wires, such as
distinguishing between Live and Ground connections, use direct contact testing with one
single test-probe via the input terminal COM or V. The COM terminal (Black) has the best
sensitivity.
