Model UT60A: 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 Multimeter Model UT60A (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, it

is equipped with a RS232C standard serial port 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.

Model UT60A: OPERATING MANUAL

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

CAT IV:Primary supply level, overhead lines, cable

systems etc.

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 8.

Model UT60A: OPERATING MANUAL

Rules For Safe Operation (1)

Warning

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.

lNever working at an effective voltage over 60V

in DC or 30V rms in AC 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 continuity,

diodes, resistance, capacitance or current.

Model UT60A: OPERATING MANUAL

Rules For Safe Operation (2)

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 leads and RS232C interface cable

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.

lThe Meter is suitable for indoor use.

lUnder the environment with high (+/-4kV)

electrostatic discharge, the Meter may not be

operated as normal condition. The user may

require resetting the Meter.

lTurn the Meter off when it is not in use and take

out the battery when not using for a long time.

lConstantly 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.
