2. Move the NCV sensor at the "
" mark on the meter clamp close to
the object to be tested. When the meter detects electric field generated by
ac voltage, the red LED on the meter will flash and the meter will indicate
the intensity of the electric field being detected. The intensity of the electric
field being detected is indicated by the number of the bar-graph segments
shown at the vertical center of the display ( see Figure 4 ), the flashing rate
of the red LED, and the beeping rate of the built-in buzzer. The higher the
intensity of the electric field is detected, the larger the number of the
bar-graph segments shown on display, the faster the flashing rate of the
red LED and beeping rate of the buzzer.
Note:
1. Detection Range: 90V - 1000V
Required Voltage Frequency: 50Hz/60Hz
2. The optimal detecting position of the meter is at the "
" mark on
the meter clamp.
3. If an ac voltage is not within the meter's detecting capacity/distance,
the meter can not detect this voltage.
4. The meter's electric field intensity indication is affected by the
magnitude of the ac voltage of the conductor under test, the distance
between the meter and the conductor, the insulation of the conductor,
etc.
