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.

• Use only with CAT III or CAT IV rated test leads.

• 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 500Hz.
  • 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.
