Important Safety Warnings

WARNING

Read entire Safety Notes section regarding potential hazards and proper instructions before using this meter. In this manual the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or actions that may damage this instrument.

WARNING

To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.

WARNING

• 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 this meter during electrical storms or in wet weather.

• Do not use the meter or test leads if they appear damaged.

• Ensure meter leads are fully seated and keep ﬁngers away from the metal probe contact when making measurements. Always grip the leads behind the ﬁnger guards molded into the probe. For information on test lead shields instructions on page 19.

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

• Use caution when working with voltages above 60 DC or 25 AC RMS. Such voltages pose shock hazards.

• 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 lockout power before measuring resistance or capacitance.

• Always adhere to national and local safety codes. Use proper personal protective equipment (PPE) to prevent shock and arc blast injury where hazardous live conductors are exposed.

• Always turn off power to a circuit or assembly under test before cutting, unsoldering or breaking the current path. Even small amounts of current can be dangerous.

• Always disconnect the live test lead before disconnecting the common test lead from the circuit.

• In the event of electrical shock, ALWAYS bring the victim to the emergency room for evaluation, regardless of victim’s apparent recovery. Electrical shock can cause unstable heart rhythms that may need medical attention.

• If any of the following occur during testing, turn off the power source to the circuit being tested: arcing, ﬂame, smoke, extreme heat, smell of burning materials or discoloration or melting of components.

WARNING

Higher voltages and currents require greater awareness of physical safety hazards. Before connecting the test leads; turn off power to the circuit under test, set meter to the desired function and range; connect the test leads to the meter ﬁrst, then connect to the circuit under test. Reapply power. If an erroneous reading is observed, disconnect power immediately and recheck all settings and connections.

• 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.

WARNING: Test Lead category protections apply only to test leads and should not be confused with the meter’s speciﬁc CAT rating. Observe the maximum category protection indicated on the meter the test leads are plugged into.

CAUTION: If the test leads need to be replaced, you must use a new one which should meet EN 61010-031 standard, rated CATIII 1000V or better.

Warranty

The EPC is warranted to be free from defects in materials and workmanship for a period of 2 years from the date of purchase. If within the warranty period your instrument should become inoperative from such defects, the unit will be repaired or replaced at UEi’s option. This warranty covers normal use and does not cover damage which occurs in shipment or failure which results from alteration, tampering, accident, misuse, abuse, neglect or improper maintenance. Batteries and consequential damage resulting from failed batteries are not covered by warranty.

Any implied warranties, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited to the express warranty. UEi shall not be liable for loss of use of the instrument or other incidental or consequential damages, expenses, or economic loss, or for any claim or claims for such damage, expenses or economic loss.

Warranty only covers hardware and does not extend to software applications.

A purchase receipt or other proof of original purchase date will be required before warranty repairs will be rendered. Instruments out of warranty will be repaired (when repairable) for a service charge.

For more information on warranty and service, contact:

www.ueitest.com • Email: [email protected]

1-800-547-5740

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

Disposal

CAUTION: This symbol indicates that equipment and its accessories

shall be subject to separate collection and correct disposal.

Cleaning

Periodically clean your meter’s case using a damp cloth. DO NOT use abrasive, ﬂammable liquids, cleaning solvents, or strong detergents as they may damage the ﬁnish, impair safety, or affect the reliability of the structural components.

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 General Speciﬁcations section, allow the instrument to return to normal operating conditions before using it.
