UNPACKINGAND INSPECTION
This clamp meter is a handheld 6600-count instrument that is designed
for use in the laboratory, field servicing, at home, and any circumstance
wherehigh current measurement is required.The clamp meter isbuilt with
a design of finger guard which ensures users operating the instrument
under a safety situation; a rugged case that is shock resistant and fire-
retardant; and electronic overload protection for all functions and ranges.
In addition, a carrying case (optional accessory) is available for easy
portability of the meter and avoiding damage.

1. Read these operating instructions thoroughly and completely be-
fore operating your meter. Pay particular attention to WARNINGS
which will inform you of potentially dangerous procedures. The
instructions in these warnings must be followed.
2. Always inspect your meter, test leads and accessories for any sign
of damage or abnormality before every use. If any abnormal condi-
tions exist (eg-broken test leads, cracked cases, display not reading,
etc.), do not attempt to take any measurements.
3. Do not expose the instrument to direct sun light, extreme tempera-
ture or moisture.
4. Never ground yourself when taking electrical measurements. Do not
touch exposed metal pipes, outlets, fixtures, etc., which might be at
ground potential. Keep your body isolated from ground by using dry
clothing, rubber shoes, rubber mats, or any approved insulating ma-
terial.
5. To avoid electric shock use CAUTION when working with voltages
above 40 Vdc or 20 Vac. Such voltages pose a shock hazard.
6. Never exceed the maximum allowable input value of any function
when taking a measurement. Refer to the specifications for maxi-
muminputs.
7. Never touch exposed wiring, connections or any live circuit when
attempting to take measurements.
8. Do not attempt to operate this instrument in an explosive atmosphere
(i.e. in the presence of flammable gases or fumes, vapor or dust).
9. When testing for the presence of voltage, make sure the voltage
function is operating properly by reading a known voltage in that
function before assuming that a zero reading indicates a no-voltage
condition. Always test your meter before and after taking measure-
ments on a known live circuit.
10. Calibration and repair of any instrument should only be performed by
qualified and trained service technicians.
11. Do not attempt calibration or service unless trained and another per-
son capable of rendering first aid and resuscitation is present.
12. Remember: Think Safety, Act Safely.

HOWTOMAKE MEASUREMENTS
Before making any measurements read safty precautions. Always
examine the instrument and accessories used with the instrument for
damage, contamination (excessive dirt, grease, etc.) and defects.
Examine the test leads for cracked or frayed insulation and make sure
the lead plugs fit snugly into the instrument terminals. If any abnormal
conditions exist, do not attempt to make any measurements.
VOLTAGEMEASUREMENTS
1. Turn off power to the device under test and discharge all capacitors.
2. Plug the black test lead into the COM input jack on the meter and conne
connect the test lead tip to a grounded point (the reference point for
measurement of voltage).
3. Set the Function/Range switch to the "V / V " position.
WARNING
To avoid possible electric shock, instrument damage and / or equip-
ment damage, do not attempt to take any voltage measurements if the
voltage is above 1000Vdc / 750Vac. 1000Vdc and 750Vac are the
maximum voltages that this instrument is designed to measure. The
"COM" terminal potential should not exceed 500V measured to
ground.

2609C.p65 ?2009/12/15, 上午 09:159

CURRENT MEASUREMENTS
WARNING
These Snap-Arounds are designed to take current measurements
on circuits with a maximum voltage difference of 500VAC between
any conductor and ground potential. Using the Snap-Around for
current measurements on circuits above this voltage may cause
electric shock, instrument damage and/or damage to the equipment
under test. Before measuring current make certain that the test
leads are removed from the instrument.
The Snap-Around is overload protected up to 500VAC for up to 1
min. Do not take current readings on circuits where the maximum
current potential is not known . Do not exceed the maximum current
that this instrument is designed to measure.
1. Set the Function/Range switch to the / position.
2. Press the trigger to open the transformer jaws and clamp them around
a conductor. Jaws should be completely closed before taking a
reading.
3. The most accurate reading will be obtained by keeping the conductor
across center of the transformer jaws.
4. The reading will be indicated on the display.
5. Reduce the range setting if set too high until a satisfactory best
resolution reading is obtained.
8
4. Plug the red test lead into the VΩ input jack on the meter and connect
the circuit where a voltage measurement is required. Voltage is al-
ways measured in parallel across a test point.
5. Turn on power the circuit /device to be measured and make the
voltage measurement reduse the range setting if set too high until a
satisfactory reading is obtained.
6. After complating the measurement, turn off power to the circuit /
device under test , dischange all capacitors and disconnect the meter
test leads.
2609C.p65 ?2009/12/15, 上午 09:1510

RESISTANCE MEASUREMENTS
1. Set the Function/Range switch to the "Ω " position. Use the "/ /
" button to select the resistance test.
2. Turn off power to the circuit under test. External Voltage across the
components causes invalid reading.
3. Connect the red test lead to the "VΩ" jack and the black test lead to the
"COM" jack.
4. Connect the test leads to the points of measurements and read the
value from the display.
CONTINUITY MEASUREMENTS
1. Set the Funtion switch to the " " position. Use the "/ / " button
to select the continuity test.
2. Turn off power to the circuit under test. External Voltage across the
components causes invalid reading.
3. Connect the test leads to the two points at which continuity is to be
tested. The buzzer will sound if the resistance is less than approxi-
mately 30Ω.
DIODE TESTS
1. Set the Function/Range switch to the " " position. Use the "/ /
" button to select the diode test.
2. Turn off power to the circuit under test. External voltage across the
components causes invalid readings.
3. Connect the red test lead to the "VΩ" jack and the black test lead to
the "COM" jack.
4. Touch probes to the diode. A forward-voltage drop is about 0.6V
(typical for a silicon diode).
5. Reverse probes. If the diode is good, "OL" is diaplayed. If the diode is
shorted, "0.00" or another number is displayed.
6. If the diode is open, "OL" is displayed in both directions.
7.Audible Indication: Less than 0.03V.
9
2609C.p65 ?2009/12/15, 上午 09:1511

CAPACITANCE MEASUREMENTS
1. Set the Function/Range switch to the " " position.
2. Connect the red test ldad to the “ VΩ“ jack and the black test lead to
the “ COM “ jack.
3. Touch the probes to the capacitor. Observe polarity when measur-
ing polarized capacitors.
4. Read the capacitance directly from the display.
5. Discharge the capacitor before taking capacitance measurements.
6. The meter has a residual capacitance in the 6.6nF and 660nF ranges,
which is a normal status. Before taking measurements, press the
Relative D button to zero the residual capacitance.
7. When the capacitor to be tested is connected, if "dIS.C" symbol indicate
on LCD, it means there is voltage existing in the tested capacitor and
to be discharged before testing.
TEMPERATURE MEASUREMENTS
1. Set the Function/Range switch to the "Temp" position.
2. Remove leads and slide the Temp switch to the right to close lead
jacks.
3.Plug any K-type thermocouple directly into the meter to measure
temperature.
4. Take temperature measurement using the thermocouple probe and
read the temperature from the display.
FREQUENCY MEASUREMENTS
1. Set the Function/Range switch to the “Hz/%“ position.
2. Connect the red test lead to the “VΩ” jack and the black test lead to
the “COM” jack.
3. Connect the test leads to the point of measurement and read the
frequency from the display.
%DUTY CYCLE MEASUREMENTS
1. Set the Function/Range switch to the “Hz/%“ position.
2. Connect the red test lead to the “VΩ” jack and the black test lead to
the “COM” jack.
3. The readings of % DUTY CYCLE measurements will show on the
sub-display.
