Electric Field EF-Detection
The meter displays "EF" when it is ready. Signal strength is indicated
as a series of bar-graph segments on the display together with variable
beep tones.
• Non-Contact EF-Detection: An antenna is located along the top-right end of the
stationary clamp jaw, which detects electric field surrounds energized conductors. It is
ideal for tracing live wiring connections, locating wiring breakage and to distinguish
between live or earth connections.
• Probe-Contact EF-Detection: For more precise indication of live wires, such as
distinguishing between Live and Ground connections, use one single probe to test via
terminal COM for direct contact EF-Detection with best sensitivity.
