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.

connection will be indicated when making a measurement.
Note:
a. In small range example mV range , the meter may
display an unstable reading when the test leads have
not been connected to the load to be measured. It is
normal and will not affect the measurements.
b. To avoid damage to the meter, don’t measure a
voltage which exceeds 600V (for DC voltage
measurement) or 600V(for AC voltage measurement)，
under CAT III conditions.and 1000V(for DC voltage)
750V(for AC voltage) under CAT II conditions.

2. Press the trigger to open the transformer jaws and clamp
one conductor only it is impossible to make measurements
when two or three conductors are clamped at the same
time.
3. Display reading is flowing the conductor AC current.
6-3. Measure Resistance
1. Connect the BLACK test lead to the “COM” jack and the
RED to the“ ”jack (Note: The polarity of the red
test lead is positive “+”).
2. Set the function switch to range.
3. Press“RANGE” button can be select manually
measurement.
4. Press “SELECT” button to select resistance
measurement mode,the symbol “MΩ” will appear as an
indicator.
5. Connect the test leads across the load to be measured.
6. Read the reading on the display.
Note:
a. For resistance measurements >1MΩ, the meter may
take a few seconds to stabilize reading. This is normal
for high-resistance measurement.
b. When the input is not connected, i.e. at open circuit,
the symbol “OL” will be displayed as an over range
indicator.
c. Before measuring in-circuit resistance, be sure that
the circuit under test has all power removed and all
capacitors are fully discharged.

6-4. Continuity Test
1. Connect the BLACK test lead to the “COM” jack and the
RED to the “ ” jack (Note: The polarity of the red
test lead is positive “+”).
2. Set the function switch to “ ” range
3. Press the “SELECT” button to select continuity
measurement mode, and the symbol “ ” will appear as
an indicator.
4. Connect the test leads across the load to be measured.
5. If the circuit resistance is lower than about 30Ω, the
built-in buzzer will sound.
6-5. Diode Test
1. Connect the BLACK test lead to the “COM” jack and the
RED to the “ ” jack (Note: The polarity of the red

the cold end (free end) of the thermocouple sensor into the
terminal (black to COM jack and red to “ ” jack).
3. Set the working end (testing end) on or inside the object
under test.
4. The value of the temperature is shown on the display in
degree centigrade (°C).
5. Press the “SELECT” button, fahrenheit and celsius can
be converted to each other.
6-7. Capacitance Measuring
1. Connect the BLACK test lead to the “COM” jack and the
RED to the “ ” jack.
2. Set the function switch at “ ” position.
(NOTE: The polarity of the RED lead is positive “+”)
3. Connect test leads across the capacitor under measure
and be sure the polarity of connection is observed.
Note: When the capacitance under measure is above
100uF, it needs at least 5 second to make readings stable.
6-8. Frequency Measuring (auto range)
1. Set the function range switch to the required “Hz/DUTY”
position.
2. Connect the BLACK test lead to the “COM” jack and the

test lead is positive “+”).
3. Connect the test leads across the load to be measured.
-14-

Note: Do not apply more than 250V RMS to the input.
Indication is possible a voltage higher than 100V rms, but
reading maybe out of specification.
At the same time using the clamp hand to test AC current,
press key, the meter shows the frequency of the
measured current.
NOTE:
a. The testing temperature is displayed automatically
when the thermocouple is put into the testing holes.
b. The surrounding temperature is shown when the
circuit of the sensor is cut off.
c. The limit temperature measured by the thermocouple
given together with the instrument is 250°C; 300°C is
acceptable within short period, if you need to measure
higher temperature,you must buy a high temperature
K type.
7. AUTO POWER OFF
If you don’t operate the meter for about 15 minutes, it will
turn off automatically. To turn on it again, just rotate the
range switch or press a button.
8. BATTERY REPLACEMENT
If the sign “ ” appear on the display, it indicates battery
should be replaced. Remove screws and open the back
case, replace the exhausted battery with new batteries
(9V NEDA 1604,6F22 equivalent).
