1. INTRODUCTION
This manual provides all safety information, operation
instruction, specifications and maintenance for the meter,
which is compact, handheld, and battery operated.
This instrument performs AC/DC voltage, AC Current,
Resistance, Audible Continuity, Diode and Temperature
measurements. It is a 3 5/6 digits, 6000 counts auto ranging
digital clamp multimeter.
DT201D digital clamp multimeter has been designed
according to EN61010-1 oncoming electronic measuring
instruments with an over voltage category (CAT III 600V
CAT II 1000V) and Pollution degree 2.
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.
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
-2-
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 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 or diodes.
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.
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.
-3-
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.
