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 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 0000
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.
• 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.
