Model UT10A: OPERATING MANUAL

Overview

Warning

To avoid electric shock or personal injury, read the “Safety Information” and

“Rules for Safety Operation” carefully before using the Meter.

Pocked-Sized Digital Multimeter Model UT10A (hereafter referred to as “the Meter”)

is a 3 3/4 digits with steady operations, fashionable structure, low power consumption

and highly reliable hand-held measuring instrument. The Meter uses large scale of

integrated circuit with double integrated A/D converter as its core. The Meter not

only can measure AC/DC Voltage, AC/DC Current, Resistance, Capacitance,

Frequency, Diodes and Continuity, but also has Relative Mode, Data Hold, Full Icon

Display, Duty Cycle and Sleep Mode features.

Model UT10A: OPERATING MANUAL

Safety Information

This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage

category (CAT. II 300V) and double insulation.

CAT. II: Local level, appliance, PORTABLE EQUIPMENT etc., with smaller transient voltage

overvoltages than CAT. III

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 9.

Rules For Safe Operation (1)

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:

Model UT10A: OPERATING MANUAL

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. Check the

test leads for continuity.

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

the terminals or between any terminal and grounding.

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.

Rules For Safe Operation (2)

Model UT10A: OPERATING MANUAL

When the Meter working at an effective voltage over 60V in DC or 30V rms

in AC, special care should be taken for there is danger of electric shock.

Use the proper terminals, function, and range 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.

When using the test leads, keep your fingers behind the finger guards.

Disconnect circuit power and discharge all high-voltage capacitors before

testing resistance, continuity, diodes or capacitance.

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.

Remove the connection between the testing leads and the circuit being

tested, and turn the Meter power off before opening the Meter case.

Rules For Safe Operation (3)

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 power 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.
