NON-CONTACT AC VOLTAGE DETECTION
In Auto Check mode, press the "SELECT" key twice. The built-in
buzzer sounds beeps, and the four bar-graph segments, which will
be are used to indicate the intensity of electrical field, appear
sequentially at the centre of the display from left to right of the
display (Figure 2). Then the four bar-graph segments drop to lower
positions of the display (Figure 3). Now the buzzer stop sounding and
the meter is in the non-contact AC voltage detection mode.
Move the left top corner of the meter close to the object to be tested.
When the meter detects an electric field generated by AC voltage, the
meter will indicate the intensity of the electrical field as described as
follows:
The intensity of the electrical field is indicated by the number of the
bar-graph segments at the centre of the display and the beeping rate
of the built-in buzzer. The higher the intensity of the detected electric
field, the larger the number of the bar-graph segments (which
appear at the centre of the display), and the faster the beeping rate
of the buzzer.
