Model UT60D: 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
"Safety Information" and "Rules for Safe Operation"
carefully before using the Meter.
Digital Multimeter Model UT60D (hereafter referred to
as "the Meter") has autorange and manual range options
with maximum reading 3400. The enclosure structure
design adopted advanced "co-injection" technique in
order to provide sufficient insulation.
In addition to the conventional measuring functions, it is
equipped with a 34 segments analogue bar graph and
RS232C standard serial port for easy connection with
computer to realize macro recording and monitoring and
capture of transient dynamic data, displaying change of
waveform during the measurement, providing data and
evidence to engineering technicians for scientific research.
This is also a highly applied digital multimeter of good
performance with full overload protection.

This Meter complies with the standards IEC61010: in
pollution degree 2, overvoltage category (CAT. III 1000V,
CAT. IV 600V) 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 on.
International electrical symbols used on the Meter and
in this Operating Manual are explained on page 8.

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:
lBefore 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.
lInspect 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.
lDo not apply more than the rated voltage, as
marked on the Meter, between the terminals or
between any terminal and grounding.
lThe 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.
lWhen 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.
lUse the proper terminals, function, and range
for your measurements.
lDo 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.
lWhen using the test leads, keep your fingers
behind the finger guards.
Rules For Safe Operation (1)

Rules For Safe Operation (2)
lDisconnect circuit power and discharge all high-
voltage capacitors before testing continuity,
diodes, resistance or current.
lBefore measuring current, check the Meter’s
fuses and turn off power to the circuit before
connecting the Meter to the circuit.
lReplace 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.
lRemove test leads and RS232C interface cable
from the Meter and turn the Meter power off
before opening the Meter case.
lWhen servicing the Meter, use only the same
model number or identical electrical
specifications replacement parts.
lThe internal circuit of the Meter shall not be
altered at will to avoid damage of the Meter and
any accident.
lSoft 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.
lThe Meter is suitable for indoor use.
lUnder the environment with high (+/-4kV)
electrostatic discharge, the Meter may not be
operated as normal condition. The user may
require resetting the Meter.
lTurn the Meter power off when it is not in use
and take out the battery when not using for a
long time.
lConstantly 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.
