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 Clamp Multimeter Model UT207A/UT208A/UT209A (hereafter referred to
as “the Meter”) are 3 3/4 digits with steady operations, fashionable structure and
highly reliable measuring instrument. The Meter uses large scale of integrated
circuit with double integrated A/D converter as its core and has full range
overload protection.
The Meter can measure AC/DC Voltage, AC/DC Current, Frequency, Duty Cycle,
Resistance, Diodes, Continuity and etc.
UT208A has an extra temperature and Capacitance feature.

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 overvoltages than CAT III.
CAT III: Distribution level, xed installation, with smaller transient overvoltages
than CAT IV.
Use the Meter only as specied in this operating manual, otherwise the protection
provided by the Meter may be impaired.
In this manual, a Warning identies conditions and actions that pose hazards to
the user, or may damage the Meter or the equipment under test.
A Note identies the information that user should pay attention to.
International electrical symbols used on the Meter and in this Operating Manual
are explained on page 9.

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. Check
the test leads for continuity. Replace damaged test leads with identical
model number or electrical specications before using the Meter.
● Do not apply more that the rated voltage, as marked on the Meter, between
the terminals or between any terminal and grounding. If the value to be
measured is unknown, use the maximum measurement position and reduce
the range step by step until a satisfactory reading is obtained.
● 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.
● The rotary switch should be placed in the right position and no any

UT207A/208A/209A Operating Manual
changeover of range shall be made during measurement is conducted to
prevent damage of the Meter.
● Do not carry out the measurement when the Meter’s back case and battery
compartment are not closed to avoid electric shock.
● Do not input higher than 1000V in DC or 750 V in AC between the two
Meter’s input terminal to avoid electric shock and damages to the Meter.
● When the Meter working at an effective voltage over 70V in DC or 33V 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, inammable and strong magnetic eld. The
performance of the Meter may deteriorate after dampened.
● When using the test leads, keep your ngers behind the nger guards.
● To avoid electric shock, do not touch the bare wires, connectors, unused
input terminals or the circuit under testing during measurement.
● Disconnect circuit power and discharge all high-voltage capacitors before
testing resistance, continuity and diode.
● 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 specications 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.
