WARNINGS

To ensure safe operation and service of the tester, 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.

• Ensure meter leads are fully seated, and keep ngers away from the
metal probe contacts when making measurements.

• Do not open the meter to replace batteries while the probes are

connected.

• Use caution when working with voltages above 60V DC, or 25V AC RMS.
Such voltages pose a shock hazard.

• To avoid false readings that can lead to electrical shock, replace
batteries if a low battery indicator appears.

• Unless measuring voltage or current, shut off and lock out power before
measuring resistance or capacitance.

• Always adhere to local and national safety codes. Use Personal
Protective Equipment (PPE) to prevent shock and arc blast injury.

This warranty gives you specific legal rights. You may also have other rights
which vary from state to state.

BATTERY REPLACEMENT

• When indicator is displayed on the LCD, batteries must be replaced.

•Remove the back screw and replace 2 x AAA batteries.

CLEANING

Turn instrument off and disconnect test leads. Clean the instrument by using
a damp cloth. Do not use abrasive cleaners or solvents.

STORAGE

Remove the batteries when instrument is not in use for a prolonged period
of time. Do not expose to high temperatures or humidity. After a period
of storage in extreme conditions exceeding the limits mentioned in the
Specifications section, allow the instrument to return to normal operating
conditions before using it.
