Overview
This Operating Manual covers information on safety and cautions. Please read the
relevant information carefully and observe all the and strictly.Warnings Notes
Warning
To avoid electric shock or personal injury, read the “Safety Information”
carefully before using the Meter.
Model UT207 and UT208 are 3 5/6 digit AC&DC digital clamp multimeters
( hereafter referred to as "the Meter" ) characterized with stable performance, high
reliability and novel structure. They are designed with large-scale integrated circuits
and dual integral A/D converter as its core and offer full-range overload protection.
The Meter can measure AC/DC Voltage, AC/DC Current, Frequency, Duty Cycle,
Resistance, Diodes, Continuity, Surge Current and etc.
UT208 has an extra temperature feature.

Warning
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 th e
test ea l ds for con inuit ty. d ged l ds th enti l m el Re acepl ama test ea wi id ca od
number or electrical specifications before using the Meter.
Do not apply more than the rated voltage, as marked on the Meter betwee , n
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
changeover of range shall be made during measurement toprevent
damage of the Meter.
Do not carry out the measurement when the Meter’s back case and batter y
compartment are not closed to avoid electric shock.
Do not input higher than 600V between the two Meter’s input terminal to
avoid electric shock and damage to the Meter.
When the Meter working at an effective voltage over 70V in DC or 33V rms is
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.
To avoid electric shock, do not touch the bare wires, connectors, unused
input terminals or the tested circuit during measurement.

testing resistance, continuity and diode.
Replace the battery as soon as the battery indicator appears. With a
low batter y, the Meter might produce false readings that can lead to electric
shock and personal injury.
When servicing the Meter, use only the replacement parts with the same
model or identical electrical specifications.
The internal circuit of the Meter shall not be altered at will to avoid damage
to 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.
