Model UT233: OPERATING MANUAL

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

ìSafety Informationî and ìRules for Safe Operationî

carefully before using the Meter.

Model UT233 is a digital power clamp meter (hereafter

referred to as ìthe Meterî) is a handheld intelligent

power meter which has both the features of digital

current meter and also power measurement meter.

The Meter can measure Voltage, Current,Active Power,

Apparent Power, Reactive Power, Power Factor, Phase

Angle, Frequency,Active Energy and Phase Sequence.

Open the package case and take out the Meter. Check

the following items carefully to see any missing or

damaged part:

Model UT233: OPERATING MANUAL

Safety Information

This Meter complies with the standards IEC61010: in

pollution degree 2, overvoltage category (CAT. III 600V,

CAT IV 300V) 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.

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 to.

International electrical symbols used on the Meter and

in this Operating Manual are explained on page 6.

Rules For Safe Operation

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:

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 leads for damaged insulation

or exposed metal. Replace damaged test leads

with identical model number or electrical

specifications before using the Meter.

Do not apply more that the rated voltage, as

marked on the Meter.

When measurement has been completed,

disconnect the connection between the test

leads and the circuit under test, remove the

Model UT233: OPERATING MANUAL

testing leads away from the input terminals of

the Meter and turn the Meter power off.

Do not carry out the measurement when the

Meterís back case and / or battery door is opened

to avoid electric shock.

When the Meter working at an effective voltage

over 30V in AC, special care should be taken.

Use the proper terminals and function 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.

Do not use the Meter if the surface of it is wet

or the userís hands are wet.

When using the test leads, keep your fingers

behind the finger guards.

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.

When opening the battery door, must make sure

the Meter is power off.

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 off when it is not in use and take

out the battery when not using for a long time.

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.
