to ensure safe operation and service of the tester, follow these instructions.
failure to observe these warnings can result in severe injury or death.
• Use extreme caution when testing live electrical circuits due to risk of injury from
electrical shock.
• When testing for high voltage, always use hot sticks and rubber gloves meeting
industry standards.
• Follow approved work safety practices and clearances per OSHA Sub-parts
R & V and your company work rules.
• Always test on a known live circuit to verify tester functionality prior to use.
• Do not exceed the limits marked on the instrument itself. Never test voltage
more than 132kV AC RMS.
• Never ground yourself when taking measurements. Do not touch exposed
circuit elements.
• Observe the proper safety precautions when working with voltage above 30V AC
RMS to avoid electrical shock hazard.
• Do not assume equipment or conductors are, or will remain, de-energized.
Always install proper grounding devices before starting procedure.
• Do not operate tester in an explosive atmosphere.
• Do not expose tester to rain or moisture. This increases the risk of fire
or electric shock.
• Do not rely on this tester for shielded wire or cable with concentric neutrals.
• Do not let the unit make contact with live line voltage. Do not touch any exposed
wiring, connections or other energized parts of an electrical circuit.
• 3-phase feeder cables with conductors close to each other may self-cancel the
electric field and not be detected by the device. Verify that the phase conductors
are separated by at least 15" (381 mm) before testing for AC voltage.
