55V (tolerance: 23V ~ 83V)
110V (tolerance: 59V ~ 165V)
220V (tolerance: 124V ~ 330V)
440V (tolerance: > 250V)
Indication: Bar graph segments & audible
beep tones proportional to the
field strength
Detection Frequency: 50/60Hz
Detection Antenna: Top end of the meter
Probe-Contact EF-Detection:
For more precise indication of live wires,
such as distinguishing between live and
ground connections, use the Red (+) test
probe for direct contact measurements.
