INSTRUCTION MANUAL

• 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 in the 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 dis­pose 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.
