Page 3: Safety Rules
Safety Rules The Hi-Prox 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. The following rules should reduce the danger: Read the user manual carefully and completely before using the tester. -
Page 4: General Description
General Description The Hi-Prox consists of an internal pickup sensor plate, a rotary switch as sensitivity selector, a sound annunciator (high pitch, high power buzzer), a visual indicator (high bright LEDs), and three "C" size batteries. The Hi-Prox detects AC voltages using the sensor plate. -
Page 5: Low Voltage Testing
Low Voltage Testing The Hi-Prox works by proximity. Physical contact with electrical conductors is not necessary when testing for live lines. Its sensor senses the radiated field which surrounds live conductors. It is recommended not to touch high voltage wires with the Hi-Prox. Radiated field strength increases with voltage and decreases quickly with distance or earth shielding. -

Page 7: Preparation For Use
Preparation for Use When unpacked, the tester should be inspected for any visible signs of damage, and the preliminary checks described in the user manual 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 8: Typical Uses
Typical Uses Identify and check live cables Check and detect live high voltage cables (using extension hot stick) Find fault in flexible cables Check earth equipment Service neon lighting Trace live wires Check high frequency radiation Detect residual or induced voltages Broken Wires In Cables Faults in damaged flexible cables are found by applying low voltage to each conductor. -
Page 9: High Voltage Testing
High Voltage Testing The rotary switch (attenuator) is used to identify and differentiate various HV live cables. The tester must be used in conjunction with a long and insulating rod when measuring high voltage (kV). Non-Contact It is advised that the tester should never come into contact with cables (kV) as this tester is merely a non-contact AC Proximity tester. -
