Model UT60B/C/E: 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.

Warning

To avoid electric shock or personal injury, read the

“Safety Information” and “Rules for Safe Operation”

carefully before using the Meter.

Digital MultimeterModelUT60B, UT60CandUT60E

(hereafter referred to as “the Meter”) has autorange and

manual range options with maximum reading 3999. The

enclosure structure design adopted advanced “co-injection”

technique in order to provide sufficient insulation.

In addition to the conventional measuring functions, there

is a RS232C standard serial port equipped with Model

UT60E for easy connection with computer to realize

macro recording and monitoring and capture of transient

dynamic data, displaying change of waveform during the

measurement, providing data and evidence to engineering

technicians for scientific research.This is also a highly

applied digital multimeter of good performance with full

overload protection and backlight function. Model UT60E

also has true rms reading for AC voltage andAC current

measurements.

Except where noted, the descriptions and instructions in

this Operating Manual apply to all Model UT60B/UT60C

/UT60E .

Unless otherwise identified, all figures show the Model

UT60B.

Unpacking Inspection

Open the package case and take out the Meter. Check the

following items carefully to see any missing or damaged part:

In the event you find any missing or damage, please

contact your dealer immediately.

Safety Information

This Meter complies with the standards IEC61010: in

pollution degree 2, overvoltage category (CAT. III 1000V,

CAT. IV 600V;)and double insulation.

CAT. III: Distribution level, fixed installation, with smaller

transient overvoltages than CAT. IV

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 6.

Rules For Safe Operation

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:

lBefore 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.

lInspect the test leads for damaged insulation or exposed

metal. Check the test leads for continuity. Replace

damaged test leads with identical model number or

electrical specifications before using the Meter.

lDo not apply more than the rated voltage, as marked on

the Meter, between the terminals or between any

terminal and grounding.

lThe 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.

lWhen the Meter working at an effective voltage over 60V

inDC or 30V rms in AC, special care should be taken for

there is danger of electric shock.

lUse the proper terminals, function, and range for your

measurements.

lDo 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.

lWhen using the test leads, keep your fingers behind the

finger guards.

lDisconnect circuit power and discharge all high-voltage

capacitors before testing resistance, continuity, diodes,

current, or capacitance.

lBefore measuring current, check the Meter’s fuses and

turn off power to the circuit before connecting the Meter

to the circuit.

lReplace 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.

lRemove test lead, temperature probe, RS232C interface

Warning

Model UT60B/C/E: OPERATING MANUAL

cable and test clip from the Meter and turn the Meter

power off before opening the Meter case.

lWhen servicing the Meter, use only the same model

number or identical electrical specifications replacement

parts.

lThe internal circuit of the Meter shall not be altered at

will to avoid damage of the Meter and any accident.

lSoft 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.

The Meter is suitable for indoor use.

Under the environment with high (+/-4kV) electrostatic

discharge, the Meter may not be operated as normal

condition. The user may require resetting the Meter.

Please take out the battery when it is not being used

for a prolonged period to avoid damages to the Meter.

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.
