Model UT232: 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 UT232 is a three phase intelligent handheld
digital power clamp meter (hereafter referred to as ìthe
Meterî) 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 etc.
Open the package case and take out the Meter. Check
the following items carefully to see any missing or
damaged part:

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 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 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

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.
The Meter is suitable for indoor use.
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.
