Instructions

Non-Contact voltage detector with visual indicator
Battery installation
Batteries: 2 x 1.5V AAA
1) Unscrew the cap (anticlockwise)
2) Insert the batteries as indicated
3) Replace the cap (clockwise)
4) To turn on, press the On/Off button once
• Green LED: stand-by mode
• Red LED: AC voltage present
5) To turn off, press the On/Off button
For safety purposes a pre-use test should be performed prior to each use.
1) Turn on by pressing the On/Off button. The green LED will illuminate indicating that the detector is in stand-by
mode.
2) Test on a known live circuit within a voltage range of 70-1,000V AC. If the red LED illuminates indicating the
presence of AC voltage then the detector is functioning correctly.
3) In the stand-by mode, touch the detector tip to the appliance/circuit under test.
4) If voltage is detected the red LED will illuminate.
If the tip fails to illuminate, voltage may still be present. Non-contact voltage detectors detect the
electrostatic field around AC energised objects. Indication may not occur for several reasons
including (though not limited to) the testing of shielded or armoured cables, the user being fully
insulated, the voltage being outside of the detectors voltage range (70-1,000V AC).
Static electricity may be generated by rubbing the plastic tip resulting in a false ‘Live’ indication.
Inspect the detector prior to use and do not used if damaged.
