A) Hold the unit in the hand by the handle below the sunrise fitting or for higher voltages an insulation stick or hot stick is recommended.
B) Turn the unit on to the 240 volt switch setting the first switch setting. This will allow for the most sensitive voltage detection.
C) Listen and watch for the self testing function which will start automatically. If this does not occur there may be a few possibilities to consider before taking out of service:-
D) To verify the tester using outside influences:-
E) Hold the detection plate side to the URD test point elbow under test a continuous tone will be heard indicating live voltage.
URD ELBOW TEST POINT
F) If a tone is not heard at this point on the 240 volt setting move the tester closer to the conductor under test, until the head of the tester is touching the conductor at this point the voltage is below 50 volts AC. Please remember that voltages over 240 volts AC require personal protective equipment, gloves and hotsticks to increase the distance from the voltage source under test.
G) If the tester activates meters away from the known source, this may not prove the signal being picked up is from that source. Use the voltage range switch to determine the voltage required for the voltage test, by moving the switch settings higher as you approach the power source under test. The unit is designed to activate 100 to 200mm away from the voltage source hand held.
