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

T o avoid electric shock or personal injury, read the
“Safety Information” and “Rules for Safe Operation”

carefully before using the Meter.

Digital MultimeterModelUT60B, UT60Cand UT60E
(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 and AC 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 (CA T. 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:

l 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.

l Inspect 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.

l Do not apply more than the rated voltage, as marked on

the Meter, between the terminals or between any
terminal and grounding.

l 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.

l When 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.

l Use the proper terminals, function, and range for your

measurements.

l 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.

l When using the test leads, keep your fingers behind the

finger guards.

l Disconnect circuit power and discharge all high-voltage

capacitors before testing resistance, continuity, diodes,
current, or capacitance.

l Before measuring current, check the Meter’s fuses and

turn off power to the circuit before connecting the Meter
to the circuit.

l

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.

l Remove test lead, temperature probe, RS232C interface

cable and test clip from the Meter and turn the Meter
power off before opening the Meter case.

l When servicing the Meter, use only the same model

number or identical electrical specifications replacement
parts.

l The internal circuit of the Meter shall not be altered at

will to avoid damage of the Meter and any accident.

l 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.

l

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.

Display Symbols (1) (see figure 2)

A measurement range determines the highest value the Meter
can measure. Most Meter functions have more than one range.
See “Accuracy Specifications.”

A.Selecting a Measurement Range

Being in the right measurement range is important:
l If the range is too low for the input, the Meter displays to

indicate an overload.

l If the range is too high, the Meter will not display the most

accurate measurement.
