Model NCVD
Non-Contact Voltage Detector
Operating Instructions
Description
1. The NCVD is used to detect the presence of
hazardous AC voltages on cables in its vicinity
without requiring electrical contact. A bar
graph display indicates the level of voltage
being detected by the NCVD. A Green LED
indicator and audible alarm alerts low battery
and the need for replacement. An optional
conductive grounding cap can be used in
conjunction with a grounding wire to avoid any
stray voltages that may create a shock hazard.
Features
To Operate The NCVD
1. Press and hold the test button. The 10
segment LED bar graph will illuminate
momentarily, then extinguish. The Green LED
will be lit solid as long as the test button is
engaged.
2. Position the voltage detection sensor close to
the cable where hazardous AC voltage is
suspected. As the device begins to detect AC
voltage, Red LEDs will illuminate from the
bottom up. Detected voltage is clearly marked
on the sides of the bar graph, beginning at 9
Volts and increasing to greater than 200 Volts.
3. If the AC voltage detected is in excess of 50
Volts, a continuous audible alarm will sound,
alerting the user of the presence of hazardous
AC voltage presence.
4. To operate the NCVD with the optional
grounding cap, install the cap on the bottom of
the unit with one end of the grounding wire
attached to the head of the cap and the other
end to a verified ground (Figure 1).

Caution!
When the test button is pressed and the bar
graph does not illuminate, the device will emit
intermittent beeps while the Green LED
indicator flashes. This signals that the battery
is depleted and needs replacement.
