WARNINGS - GENERAL
To ensure safe operation and service of the meter, follow these instructions.
Failure to observe these warnings can result in severe injury or death.
• Before each use verify meter operation by measuring a known voltage
or current.
• Never use the meter on a circuit with voltages that exceed the category
based rating of this meter.
• Do not use the meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear to be damaged.
• Probe assemblies to be used for MAINS measurements shall meet IEC/EN
61010-031 with a voltage RATING of CAT IV 600V or better.
• Ensure meter leads are fully seated, and keep fingers away from the
metal probe contacts when making measurements.
• Use caution when working with voltages above 25V AC RMS or 60V DC.
Such voltages pose a shock hazard.
• To avoid false readings that can lead to electrical shock, replace batteries
when a low battery indicator appears.
• Do not attempt to measure resistance or continuity on a live circuit.
• Always adhere to local and national safety codes. Use personal protective
equipment to prevent shock and arc blast injury where hazardous live
conductors are exposed.
• To avoid risk of electric shock, disconnect leads from any voltage source
before removing battery door.
• To avoid risk of electric shock, do not operate meter while battery door is removed.
WARNINGS - NCV FUNCTION
• When NCV Function is initiated, a blinking or steady red glow and an audible
beep indicate voltage present. If no indication, voltage could still be present.
• Before and after each use of the NCVT, verify operation by testing a known
working circuit that is within the rating of this unit.
• Never assume neutral or ground wires are de-energized. Neutrals in multi-wire
branch circuits may be energized when disconnected and must be retested
before handling.
• The NCV tester WILL NOT detect voltage if:
• The wire is shielded.
• The
operator is not grounded or is otherwise isolated from an effective earth ground.
• The voltage is DC.
• The NCV tester MAY NOT detect voltage if:
• The user is not holding the tester.
• The user is insulated from the tester with a glove or other materials.
• The wire is partially buried or in a grounded metal conduit.
• The tester is at a distance from the voltage source.
• The field created by the voltage source is blocked, dampened, or otherwise
interfered with.
• The frequency of the voltage is not a perfect sine wave between 50 and 60Hz.
• The tester is outside of operation conditions (listed in Specifications section).
• Operation may be affected by differences in socket design and insulation
thickness and type; tester may not be compatible with some types of standard
or tamper resistant (TR) electrical outlets.
• Do not apply to uninsulated hazardous live conductors.
• Detection above 50V is specified under “normal” conditions as specified below.
The tester may detect at a different threshold at different conditions, or may not
detect at all unless:
• The
tip of the tester is within 0.25" of an AC voltage source radiating unimpeded.
• The user is holding the body of the tester with his or her bare hand.
• The user is standing on or connected to earth ground.
• The air humidity is nominal (50% relative humidity).
• The tester is held still.
