4−1 Releasing Pointer Lock
Slide the pointer lock button to the right
position to unlock the pointer.
4−2 Meter Zero Adjustment
Set the pointer at the center of the
“ 0”mark on the scale by rotating the zero
adjuster with a screw driver.
5−1 AC Current Measurement
5-2 AC Voltage Measurement 4−3 Checking Battery Voltage
a. Set the range switch to the “
× 1Ω”
position.
b. Insert the red test lead into the OHM
terminal and the black test lead to the
COM terminal.
c. With the test leads shorted, try to set the
pointer over the “0” mark at the right end
of the resistance scale, using the OHM
zero adjuster.
d. When the adjustment brings the pointer
over the “0” mark, proceed to
measurement. If not, replace the battery.
(See section 7 for battery and fuse
replacement.)
NOTE
・The battery is needed only in resistance
measurement. AC/DC voltage and AC
current measurement can be made
without the battery.
・If the instrument does not operate
properly even after battery replacement,
check the fuse and test leads.
a. Set the range switch to the “AC 300A”
position.
b. Press the trigger to open the transformer
jaws and clamp onto one conductor only.
It is recommended that the conductor be
placed at the center of the closed jaws.
c. Take the reading on the 300A current
scale.
d. Set the range switch to the appropriate
position based on the reading.
e. Take the reading on the appropriate scale.
NOTE
・During current measurement, keep the
transformer jaws fully closed. Otherwise,
accurate measurement cannot be made.
The maximum conductor size is 33mm in
diameter.
・When measuring a larger current, the
transformer jaws may buzz. This is not a
fault and does not affect the accuracy at
all.
a. Set range switch to an AC voltage
position. When the order of the voltage
under test is not known, set the range
switch to the highest 600V range.
b. Insert the red test lead to the V terminal
and the black test lead to the COM
terminal.
c. Connect the tip of the test leads to the
circuit under test.

WARNING
Read through and understand instructions
contained in this manual when using the
instrument.
Save and keep the manual handy to enable
quick reference whenever necessary.
Be sure to use the instrument only in its
intended applications and to follow
measurement procedures described in the
manual.
Be sure to understand and follow all safety
instructions contained in the manual.
Failure to follow the above instructions
may cause injury, instrument damage
and/or damage to equipment under test.
CAUTION
Make sure that the range switch is set to an
appropriate position before making measurement.
Always make sure to insert the plug of each test
lead fully into the appropriate terminal on the
instrument.
When the instrument will not be in use for a
long period of time, place it in storage after
removing the batteries.
Do not expose the instrument to the direct sun,
extreme temperatures or dew fall.
Use a damp cloth and detergent for cleaning
the instrument. Do not use abrasives or solvents.
WARNING
・Do not make measurement on a circuit
above 600V AC. This may cause shock
hazard or damage to the instrument or
equipment under test.
・Transformer jaw tips are designed not
to short the circuit under test. If
equipment under test has exposed
conductive parts, however, extra
precaution should be taken to minimize
the possibility of shorting.
・Do not make measurement with the
bottom case removed.
・Do not make current measurement with
the test leads connected to the
instrument.
・Do not measure current exceeding the
limit for the overload protection feature.
・Keep your fingers and hands behind the

○Measurement categories(Over-voltage categories)
To ensure safe operation of measuring
instruments, IEC61010 establishes safety
standards for various electrical environments,
categorized as CATⅠto CATⅣ, and called
measurement categories.
Higher-numbered categories correspond to
electrical environments with greater momentary
energy, so a measuring instrument designed for
CATⅢ environments can endure greater
momentary energy than one designed for CATⅡ
CAT.Ⅰ: Secondary electrical circuits connected to
an AC electrical outlet through a
transformer or similar device.
CAT.Ⅱ: Primary electrical circuits of equipment
connected to an AC electrical outlet by a
power cord.
CAT.Ⅲ: Primary electrical circuits of the equipment
connected directly to the distribution
panel, and feeders from the distribution
panel to outlets.
CAT.Ⅳ: The circuit from the service drop to the
service entrance, and to the power meter
and primary over-current protection
device(distribution panel).
