Model UT602/603: OPERATING MANUAL

To avoid electric shock or personal injury, read the

“Safety Information” and “Rules for Safety Operation”

carefully before using the Meter.

Warning

Model UT602/603: OPERATING MANUAL

Overview

This Operating Manual covers information on safety and

cautions. Please read the relevant information carefully

and observe all the Warnings and Notes strictly.

Digital Inductance Capacitance Meter Model UT602/UT603

(hereafter referred to as “the Meter”) is a 3 1/2 digits with

steady operations, fashionable design and highly reliable

hand-held measuring instrument.

The UT602 can measure inductance, while UT603 can

measure capacitance and inductance. They both can

measure resistance, transistor, diode and continuity buzzer

UT602 has an extra Data Hold feature.

Safety Information

This Meter complies with the standards EMC EN61326.

Use the Meter only as specified in this operating manual,

otherwise the protection provided by the Meter may be

impaired.

In this manual, a Warning identifies conditions and actions

that pose hazards to the user, or may damage the Meter

or the equipment under test.

A Note identifies the information that user should pay

attention on.

International electrical symbols used on the Meter and in

this Operating Manual are explained on page 7.

To avoid possible electric shock or personal injury,

and to avoid possible damage to the Meter or to the

equipment under test, adhere to the following rules:

Warning

Before using the Meter inspect the case. Do not use

the Meter if it is damaged or the case (or part of the

case) is removed. Look for cracks or missing plastic.

Pay attention to the insulation around the connectors.

Inspect the test clips for damaged insulation or

exposed metal. Check the test clips for continuity.

Replace damaged test clips with identical model

number or electrical specifications before using the

Meter.

Do not apply voltage to the Meter.

The rotary switch should be placed in the right

position and no any changeover of range shall be

made during measurement is conducted to prevent

damage of the Meter.

Do not apply more than 30Vrms between the

terminals and the grounding to avoid electric shock

and damage to the Meter.

Use the proper terminals, function, and range for

your measurements.

Do not use or store the Meter in an environment of

high temperature, humidity, explosive, inflammable

and strong magnetic field. The performance of the

Meter may deteriorate after dampened.

Disconnect circuit power and discharge all high-

voltage capacitors before testing resistance,

continuity, capacitance or diodes.

Replace the battery as soon as the battery indicator

appears. With a low battery, the Meter might

produce false readings that can lead to electric shock

and personal injury.

Rules For Safe Operation

Model UT602/603: OPERATING MANUAL

Remove test clips from the Meter and turn the Meter

power off before opening the Meter case.

When servicing the Meter, use only the same model

number or identical electrical specifications

replacement parts.

The internal circuit of the Meter shall not be altered

at will to avoid damage of the Meter and any accident.

Soft cloth and mild detergent should be used to

clean the surface of the Meter when servicing. No

abrasive and solvent should be used to prevent the

surface of the Meter from corrosion, damage and

accident.

Turn the Meter power off when it is not in use and

take out the battery when not using for a long time.

Please constantly check the battery as it may leak

when it has been using for some time, replace the

battery as soon as leaking appears. A leaking battery

will damage the Meter.
