The 275HP / 500HP is a HIGH VOLTAGE proximity detector. 275HP has eight voltage detection settings from 240Vac to 275KVac. & 500HP has 10 Voltage detection settings from 240V to 500KV. The 275HP / 500HP consists of an internal pickup sensor plate, a sensitivity selector, a visual and a sound annunciator. With the 275HP / 500HP physical contact with electrical conductors is not necessary when testing for live lines. This tester works by proximity. Checking or proofing the tester is easy. Switch the sensitivity to 240V AC and place the dome against a low voltage live conductor or rub the dome with a cloth or against an item of clothing as this generates a static DC which triggers the detection of circuit. The light and beeper should go “on” as if a live wire is being approached. Approaching the dome near a computer screen or a TV screen (not liquid crystal display type) should also trigger the tester while on 240V selection. 

The 273 HP is a Non-contact voltage detector. It has two ranges for selection. The 273 HP consists of an internal pickup sensor, a function selection switch, a visual and a sound annunciator. With the 273 HP, physical contact with electrical conductors is not necessary when testing for live lines. Its sensor senses the radiated field which surrounds live conductors. Radiated field strength increases with voltage and decreases quickly with distance or earth shielding. Some of the typical applications are : non-contact detection of live voltages; find faults in cables; check & detect live high voltage cables; trace live wires; check high frequency radiation; check grounding equipment ; detect residual or induced voltages.
