Page 3: Safety Rules
1. Safety rules The Personal Safety voltage detector has been designed with safety in mind. However, no design can completely protect against incorrect use. Electrical circuits are dangerous and lethal through lack of caution or poor safety practice. Please follow safety rules to reduce danger and practice safety. -
Page 4: General Description
2. General description The voltage detector consists of an internal pickup AC sensor plate, a test (oscillator) and diagnostic circuit, an adjustable threshold comparator, a sound annunciator (buzzer), a visual indicator (super high bright led) and a 9V battery, all enclosed into the robust "beeper"... -
Page 5: Check It And Get It Going
4. Check it and get it going After inserting the battery, close the cover. The voltage detector will be ON automatically. a. Check the working of voltage detector Once the battery has been inserted, wait for a few seconds. If no beep and no flash occurs, press simultaneously the 2 push buttons. -
Page 6: Priority Of Functions - Display And Sound Alerts
d. Priority of functions - display and sound alerts (1) = Voltage Detected = First Priority = the tester beep and flash twice per second. (2) = Simulated Test = Voltage Detected = Second Priority (identical to 1St priority) = the tester beeps and flashes twice per second. (3) = Battery Indication = Third Priority = the tester beeps and.every 5 seconds. -
Page 7: Low Voltage Testing
5. Low voltage testing Physical contact with electrical conductors is not necessary when testing for Live Lines proximity. This tester works by proximity. Its sensor senses the radiated field which surrounds live conductors. It is recommended not to touch High Voltage wires with the voltage detector. -

Page 10: Preparation For Use
9. Preparation for use When unpacked, the tester should be inspected for any visible signs of damage, and the preliminary checks described (depress both push button for proofing the unit) should be performed to ensure that it is operating correctly. If there is any sign of damage, or if the instrument does not operate correctly, return it to your nearest supplier. -
Page 11: Broken Wires In Cables
12. Broken wires in cables Faults in damaged flexible cables are found by applying low voltage to each conductor in turn, earthing the remainder and moving the tester along the cable until the change in condition is obtained (flexible cables as used in mining and building industries are readily repairable when the break in the cable is located). -
Page 12: Replacing The Battery
Problems can be arose when the tertiary circuit of a 275/133/11kV transformer is tested. The electric field of the H.V. And M.V. Bus bars can trigger the detector when it is about 3m above the ground (this is common with most of the electric field voltage detectors and the users should be aware of it). -
