Typical Voltage Bar Graph
Indication
20V (tolerance:10V~36V) -
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.
