Indication: Bar-graph segments & audible beep tones proportional to
the field strength
Detection Frequency: 50/60Hz
Detection Antenna: Inside the top side of the stationary jaw
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.
