•Read the safety precautions associated with the equipment being

tested and seek assistance or advice when performing

unfamiliar tasks.

• Keep your fingers away from the test lead metal probe contacts

and bus-bars when making measurements. Always grip the

instrument and test-leads behind the hand guards (molded into

the probes).

•In the event of electrical shock, ALWAYS bring the victim to

the emergency room for evaluation, regardless of the victim’s

apparent recovery. Electrical shock can cause an unstable heart

rhythm that may need medical attention.

Safety Notes

Before using this meter, read all safety information carefully. 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!

Exceeding the specified limits of this meter is dangerous and can

expose the user to serious or possibly fatal injury.

•DO NOT attempt to measure any voltage that exceeds 600 volts

with this meter - UEi offers numerous alternatives for measuring

high voltage and current

• Voltages above 60 volts DC or 30 volts AC may constitute a

serious shock hazard

•DO NOT attempt to use this meter if either the meter or the test

leads have been damaged. Send unit in for repair by a qualified

repair facility

• Test leads must be fully inserted prior to taking measurements

•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 a circuit

•When measuring high voltage, disconnect the power source before

making test lead connections. Connect the test leads to the meter

first then to the circuit under test. Reapply power

•If any of the following indications occur during testing, turn

off the power source to the circuit under test:

•Arcing

•Flame

•Smoke

•Extreme Heat

•Smell of Burning Materials

•Discoloration or Melting of Components

DC Voltage Measurement

WARNING!

Maximum input voltage of DC V range is 600V DC. Do not attempt to

take any voltage measurement that exceeds 600V DC to avoid electrical

shock and/or damage to the instrument.

1. Set the rotary switch to the 600V “ “ range.

2. Connect the black and red test leads to the “COM” and “VΩ”

terminals respectively.

3. Connect the test leads to the circuit being measured and read

the displayed value (Fig 2).

Operating Instructions

If the current under measurement is higher than the selected value for a

long period, overheating may take place, compromising the safety and

operation of inner circuits.

WARNING!

DO NOT measure currents on high-voltage conductors (>600V) to avoid

risk of discharge and/or incorrect readings.

AC Current Measurement

WARNING!

Make certain that all test leads are disconnected from the

meter terminals.

1. Set the rotary switch to the desired A~range.

2. Clamp the current transducer (jaw) around one of the conductors

under test. Make sure that the clamp jaw is closed (Fig 1).

3. Read the display value.

4. When only the figure “1” is displayed, it indicates over-range

situation and the higher range has to be selected.

Continuity Measurement

WARNING!

Before taking any in-circuit resistance measurements, remove power

from the circuit being tested and discharge all capacitors.

1. Set the rotary switch to “ Ω“ range.

2. Connect the black and red test leads to the “COM” and “VΩ”

terminals respectively.

3. Connect the test leads to the resistance in the circuit being

measured (Fig 5).

4. When the test lead to the circuit is below 50Ω, it will be indicated

by a continuous beeping.

NOTE: Continuity test is available to check open/short of the circuit.

AC Voltage Measurement

WARNING!

Maximum input voltage of AC V range is 600Vrms. Do not attempt to

take any voltage measurement that exceeds 600Vrms to avoid electrical

shock hazard and/or damage to the instrument.

1. Set the rotary switch to the 600V~range.

2. Connect the black and red test leads to the “COM” and “VΩ”

terminals respectively.

3. Connect the test leads to the circuit being measured and read

the displayed value (Fig 3).

Resistance Measurement

WARNING!

Before taking any in-circuit resistance measurements, remove power

from the circuit being tested and discharge all capacitors.

1. Set the rotary switch to the 600V~range.

2. Connect the black and red test leads to the “COM” and “VΩ”

terminals respectively.

3. Connect the test leads to the circuit being measured and read

the displayed value (Fig 4).

WARNING!

Under NO circumstance should you expose batteries to extreme heat or

fire as they may explode and cause injury.

3. Place a fresh 9V battery inthe compartment.

NOTE: If you do not plan to use the meter for a month or more,

remove the battery and store it in an area that won’t be damaged by a

leaking battery.

4. Reattach the battery compartment cover to the meter and

reinstall the screw.

Periodic service

WARNING!

Repair and service of this instrument is to be performed by qualified

personnel only. Improper repair or service could result in physical

degradation of the meter. This could alter the protection from

electrical shock and personal injury this meter provides to the

operator. Perform only those maintenance tasks that you are

qualified to do.

These guidelines will help you attain long and reliable service from

your meter:

1. Calibrate your meter annually to ensure it meets original

performance specifications.

2. Keep your meter dry. If it gets wet, wipe it dry immediately. Liquids

damage electronic circuits.

3. Whenever pra c t i cal, keep the meter away from dust and dirt, which

can cause premature wear.

4. Although your meter is built to withstand the rigors of daily use, it

can be damaged by severe impacts. Use reasonable caution when

using and storing the meter.

Cleaning and Decontamination

Periodically clean your meter’s case using a damp cloth. DO NOT use

abrasives, cleaning solvents or strong detergents, as they may damage

the finish or affect the reliability of the structural components.

Battery Replacement

Always use a fresh replacement battery of the specified size and type.

Immediately remove the old or weak battery from the meter and dis-

pose of it in accordance with your local disposal regulations. Old or

defective batteries can leak chemicals that corrode electronic circuits.

WARNING!

To avoid electric shock, be sure to turn off the meter’s power and

disconnect both test leads from any equipment before you remove

or install batteries.

To install a new battery, follow these procedures:

1. Remove the screw from the battery compartment cover on the

back of the meter and lift the cover.

2. Remove and discard the old battery. Always dispose of old batteries

promptly in a manner consistent with local disposal regulations.
