Model UT205A/206A: 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 Safety Operation” carefully before using the Meter.

The Model UT205A and UT206A (hereafter referred to as “the Meter”) are a low

consumption AC clamp meter with stabilize functions, safety operations, and reliable

performance.

In addition to theAC current feature, it can also measureAC/DC voltages, resistance,

diode, continuity, frequency and temperature.

Except where noted, the descriptions and instructions in this Operating Manual apply

to both the Model UT205A/UT206A.

Safety Information

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

category (CAT. II 600V / CAT III 300V) and double insulation.

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

voltage overvoltages than CAT. III

CAT. III: Distribution level, fixed installation, with smaller transient overvoltages than

CAT. IV.

Under the influence of Radiated, Radio-Frequency Electromagnetic Field phenomenon,

the captioned model may malfunction and can self-recover after the test.

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.

Model UT205A/206A: OPERATING MANUAL

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:

Check for the lever is in good condition when measuring AC current.

Must center the wire (conductor) within the transformer jaw.

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. Replace damaged test leads with identical model number

or electrical specifications before using the Meter.

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.

When the Meter working at an effective voltage over 60V in DC or 42V rms in

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

Warning

Model UT205A/206A: OPERATING MANUAL

Use the proper terminals, function, and range for your measurements.

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

Disconnect circuit power and discharge all high-voltage capacitors before testing

To avoid harms to you or damages to the Meter from electric shock, please do

not attempt to apply higher than 600V between the terminals and grounding.

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 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.

Model UT205A/206A: OPERATING MANUAL

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
