9. 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.
# CAUTION
◦ Do not mix new and old batteries
◦ Make sure to install battery in correct polarity as
indicated inside the battery compartment.
When is shown on the display, replace
the batteries. Note that when the battery is
completely exhausted, the display blanks without
shown.
(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 R03 or equivalent
batteries.
(4) Mount and screw the battery compartment
cover.
NOTE
◦
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."
8. Other Functions
8-1 Sleep Function
NOTE
The instrument still consumes small amount of
battery power in the sleep mode. Make sure to
set the function selector switch to the " " OFF
position after use.
(1) Sleep Mode
This is a function to prevent the instrument
from being left powered on in order to conserve
battery life. This function causes the instrument to
automatically enter the sleep (powered down) mode
about 10 minutes after the last switch or button
operation.
To exit the sleep mode, turn the function selector
switch back to " ", then to any other position, or OFF
press any button.
(2) How to disable the sleep mode
To disable the sleep mode, Power the instrument
on with the data hold switch pressed. "P.OFF" is
shown on the display for about 3 seconds after the
instrument is powered on.
To enable the sleep mode, power the instrument
off, then power it on without pressing the data hold
switch.
8-2 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 held
regardless of subsequent changes in input. " " is
shown on the upper left corner of the display while
the instrument is in the data hold mode.
To exit the data hold mode, press the data hold
switch again.
NOTE
◦
If the instrument in the data hold mode enters
the sleep mode, the data hold mode will be
cancelled.
◦
At DC 40A range, if the data hold switch is
pressed for more than 2 seconds, 0 ADJ.
Function operates.
NOTE
When current flows from the upside to the
underside of the instrument, the polarity of the
reading is positive (+). Othewise, the polarity of
the reading is negative (-).
6. Voltage Measurement

2. Safety Warnings
◦
This instruction manual contains warnings and
safety rules which must be observed by the user to
ensure safe operation of the instrument and retain
it in safe condition. Therefore, read through these
operating instructions before using the instrument.
# WARNING
◦
Read through and understand instructions contained
in this manual before using the instrument.
◦ Save and keep the manual handy to enable
quick reference whenever necessary.
◦ The instrument is to be used only in its intended
applications.
Understand and follow all the safety instructions
contained in the manual.
Failure to follow the instructions may cause injury,
instrument damage and/or damage to equipment
under test. Kyoritsu is by no means liable for any
damage resulting from t he inst rume nt in
contradiction to this cautionary note.
◦ Always make sure to insert each plug of the test
leads fully into the appropriate terminal on the
instrument.
◦ Make sure to remove the test leads from the
instrument before making current measurement.
◦ Do not expose the instrument to the direct sun,
extreme temperatures or dew fall.
◦ Be sure to set the function selector switch to the
position after use. When the instrument will
not be in use for a long period of time, place it in
storage after removing the battery.
◦ Use a damp cloth and detergent for cleaning the
instrument. Do not use abrasives or solvents.
◦This instrument isn't dust & water proofed. Keep
away from dust and water.
Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instruments, IEC
61010 establishes safety standards for various electrical
environments, categorized as O to CAT IV, and called
measurement categories.
Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring
instrument designed for CAT III environments can endure
greater momentary energy than one designed for CAT II.
O : Circuits which are not directly connected to the
mains power supply.
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
overcurrent protection device (distribution panel).

4. Preparation for Measurement
4-1 Checking Battery Voltage
Set the function selector switch to any position
other than . When the display is clear without
s howing, proceed t o me asu-rem ent.
When the display blanks or is indicated,
replaces the batteries according to the instructions
described in section 9. Battery Replacement.
NOTE
The sleep feature automatically turns the instru-
ment 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 . To operate the
instrument in this case, set the switch back to
the position, then to the desired position,
or press any switch. If the display still blanks, the
batteries are exhausted. Replace the batteries.
4-2 Checking Switch Setting and Operation
Make sure that the function selector switch is set
to the correct position and the data hold switch
is deactivated. Otherwise, desired measurement
cannot be made.
5. Current Measurement
#
WARNING
◦ Do not make measurement on a circuit with a
voltage higher than 600 V AC/DC. 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 parts, however, extra
precaution should be taken to avoid possible
shorting.
◦ Do not make measurement with the battery
compartment cover removed.
◦ Do not make current measurement with the test
leads connected to the instrument.
◦ It is a part providing protection against electrical
shock and ensuring the minimum required air
and creepage distances. Keep your fingers and
hands behind the barrier during measurement.
NOTE
◦
During current measurement, keep the trans-
former jaws fully closed. Otherwise, accurate
measurement cannot be made. The maxi-mum
conductor size is 30 mm in diameter.
◦
When measuring a larger current, the trans-
former jaws may buzz. This does not affect the
instrument's accuracy.
5-1 AC Current Measurement
( )1 Set the function selector switch to theACA
position.
( )2 Press the trigger to open the transformer jaws
and clamp onto one conductor only.
( )3 Take the reading on the display.
5-2 DC Current Measurement
( )1 Set the function selector switch to the
DCA position
( )2 With the transformer jaws closed and without
clamping them onto the conductor, press the
0 ADJ. Switch for more than 2 seconds to
zero adjust the display. (less than 2 seconds
: Data Hold Function operates.)The 0 ADJ.
Switch is enabled only on DC 40A range.
( )3 Press the trig
ger to open the transformer
jaws and clamp onto one conductor only.
( )4 Take the reading on the display.
