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).

OPERATING INSTRUCTIONS

CONNECTING TEST LEADS
Do not test if leads are improperly seated. Results could cause intermittent display readings. To ensure proper connection, firmly press leads into the input jack completely. TESTING IN CAT III / CAT IV MEASUREMENT LOCATIONS
Ensure the test lead shield is pressed firmly in place. Failure to use the CATIII / CATIV shield increases arc-flash risk. TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III / CAT IV shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets. Take care not to lose the shields. AC CURRENT (LESS THAN 600A)
AC Current is measured by pressing the clamp trigger 10 to open the clamp 3 and placing it around a current-carrying wire. When measuring, care should be taken to ensure that the clamp 3 is completely closed with trigger 10 fully released, and that the wire passes perpendicularly through the center of the clamp 3 in line with the arrow markings 11 . NOTE: Current measurement can be made by clamping around single conductors, but not cables containing both live and neutral wires. In this case a line splitter is required, Klein Cat. No. 69409 is recommended.
To measure current:

1. Rotate the Function Selector switch 2 to the AC current A setting.
2. Place clamp 3 around wire. The current measurement will be shown in the display. The meter will auto-range to display the measurement in the most appropriate range.
