instructions may cause injury instrument damage
and/or damage to equipment under test.
WARNING
The symbol indicated on the instrument means that
the user must refer to related parts in the manual for safe
operation of the instrument, be sure to carefully read the
instruction following each symbol in this manual.
DANGER is reserved for conditions and actions
that are likely to cause serious or fatal injury.
WARNING is reserved for conditions and actions
that can cause serious or fatal injury.
CAUTION is reserved for conditions and action that
can cause minor injury or instrument damage.
— Never make measurement on a circuit with a voltage
higher than 600V AC/DC.
— Do not attempt to make measurement in the
presence of flammable gaffes, fumes, vapor or dust.
Otherwise, the use of the instrument may cause
sparking, which can lead to an explosion.

4. Preparation for Measurement
4-1. Checking battery Voltage
Set the function selector switch to any position other than
“OFF”. When the display is clear without “ ” showing
proceed to measurement. When the display blank or “ ”
is indicated, replaces the batteries according to the
instructions described in section 8. Battery Replacement.
NOTE
The sleep feature automatically turns the instrument
off in a certain period of time after the last switch
operation. Therefore, the display may be blank with the
function selector switch set to a position other than
“OFF”. To operate the instrument in this case. Set the
Switch back to the “OFF” position, then to the desired
position, or press any switch. If the display still blanks,
the batteries are exhausted. Replace the batteries.
(1) Set the function switch at “2/20A~” or “400A~” range and press
the trigger to open the transformer jaws and clamp them around
a conductor.
(2) 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.
• During current measurement, keep the transformer
jaws fully closed. Otherwise accurate measurement
cannot be made. The maximum conductor size 30mm
in diameter.
• When measuring a larger current, the transformer
jaws may buzz. This does not affect the instrument’s
accuracy.
5-2. AC Voltage Measurement
• Never use the instrument on a circuit with a voltage
higher that 600V AC. Otherwise, electric shock hazard
or damage to the instrument or the circuit under test
may result.
• Do not make measurement with the battery
compartment cover removed.
DANGER
(1) Set the function Selector switch to the “V~” position.
(2) Plug the red test lead into the V/W terminal and the
black test lead into the COM terminal.
(3) Connect the test lead prods to the circuit under test
and take the reading on the display.

5. Measurement
5-1. Current Measurement
• Do not make measurement on a circuit with a voltage
higher than 600V AC. Otherwise, shock hazard or
damage to the Instrument or equipment under test
may result.
• Transformer jaw tips are designed to minimize the
possibility of shorting conductors in the circuit under
test If equipment under test has exposed conductive
part, however, extra precaution should be taken to
avoid possible shorting.
• Do not make measurement with the battery
compartment cover removed.
WARNING

take the reading on the display.
(1) Set the function selector switch to the “200 " position.
(2) Plug the red test lead into the V/ terminal and the black
test lead into the COM terminal.
(3) Connect the test lead prods to the circuit under test and
take the reading on the display.
W
• Always make sure that the circuit under test is
powered off.
• Do not make measurement with the battery
compartment cover removed.
5-4. Resistance Measurement
DANGER
• When shorting the test lead prods together, the
display may show a very small resistance instead
of “0". This is the resistance of the test leads.
• If one of the test leads has an open, the display reads “OL”.
NOTE
DANGER
• Always make sure that the circuit under test is
powered off.
• Do not make measurement with the battery
compartment cover removed.
(1) Set the function selector switch to the “ / " position.
(2) Plug the red test lead into the V/W terminal and the black
test lead into the COM terminal.
(3) Press the FUNC key and set the instrument to continuity
check mode.
(4) Connect the red test lead across the resistance to be measured.
The buzzer if the resistance of the circuit measured is lower
than approximately 50W
(1) Set the function selector switch to the “ / " position.
(2) Plug the red test lead into the V/W terminal and the black
test lead into the COM terminal.
(3) Press the FUNC key and set the instrument to diode test
mode.
(4) Connect the red test lead anode, the black lead to cathode
of the diode under the testing.
(5) You can get reading from LCD.
DANGER
• Always make sure that the circuit under test is powered off.
• Do not make measurement with the battery compartment
cover removed.
5-6. Diode Test
5-5. Continuity Test
• When shorting the test lead prods together, the
display may show a very small resistance instead
of “0". This is the resistance of the test leads.
• If one of the test leads has an open, the display reads “OL”.
NOTE
5-7. NCV (Non-contact voltage)
(1) Set the function selector switch to “NCV” position.
(2) Test leads are not used for the NCV test, the display
goes blank and the LED will flash a bright red light.
(3) Hold the top center of the clamp meter close to the
conductor circuit in question.
(4) If a voltage in the range of 150 to 600V AC is present,
the LED will continuously flash a bright red light.
(5) After stop working for 3 minutes, the meter will be
into sleep mode (set the function selector switch to
“NCV” position again to restart the power).
6. Data Hold Function
This is a function used to freeze the measured value on the
display. Press the data hold switch to freeze the reading.
The reading will be hold regardless of subsequent changes in
input. “H” is show on the down left corner of the display while
the instrument is the date hold mode. To exit the data hold
mode, press the data hold switch again.
7. MAX function
Max is the maximum value hold key that acts with trigger.
After pressing the key, A/D will keep working, and the
display value are always updated and kept the maximum
value. (The actual gained value is not the peak value, but
maximum value.)
8. Battery Replacement
WARNING
To avoid electric shock hazard, make sure to set
the function selector switch to “OFF” and remove
the test leads from the instrument before trying
to replace the batteries.
When “ ” is shown on the display, replace the batteries.
Note that when the battery is completely exhausted, the
display blanks without “ ” show.
(1) Set the function selector switch to the “OFF” position
(2) Unscrew and remove the battery compartment on the
bottom of the instrument.
(3) Replace the batteries observing correct polarity. Use two
new AAA or equivalent batteries.
(4) Mount and screw the battery compartment cover.

CAUTION
• Do not mix new and old batteries.
• Make sure to install battery in correct polarity bas
indicated inside the battery compartment.
• When shorting the test lead prods together, the
display may show a very small resistance instead
of “0". This is the resistance of the test leads.
• If one of the test leads has an open, the display reads “OL”.
