DANGER
● Never make measurements under the circumstances
exceeding the designed measurement category and the
rated voltage of the instrument.
● Do not attempt to make measurement in the presence of
flammable gasses. Otherwise, the use of the instrument
may cause sparking, which can lead to an explosion.
● Never attempt to use the instrument if its surface or your
hand is wet.
● Do not exceed the maximum allowable input of any
measuring range.
● Never open the case during a measurement.
● To avoid electrical shock by touching the equipment under
test or its surroundings, be sure to wear insulated
protective gear.
● Barriers on the test leads provide protection to keep your
fingers and hands from touching an object under test.
Keep your fingers and hands behind the barriers during
measurement.
WARNING
● Never attempt to make measurement if any abnormal
conditions, such as broken case and exposed metal
parts are found on the instrument or test leads.
● Verify proper operation on a known source before use or
take action as a result of the indication of the
instrument.
● Firmly attach the caps to the test leads when
performing measurements in CAT III test
environments.
● Do not rotate the function switch if the instrument
and the equipment under test are connected.
● Do not install substitute parts or make any modification to
the instrument. For repair or re-calibration, return the
instrument to your local KYORITSU distributor.
CAUTION
● Use of this instrument is limited to domestic, commercial
and light industry applications. Strong electromagnetic
interference or strong magnetic fields, generated by
large currents, may cause malfunction of the instrument.
● Set the function switch to an appropriate position before
starting measurement.
● This instrument isn’t dust & water proofed. Keep away
from dust and water.
● Do not pull or twist the test leads to prevent the risk of
damage.
● Power off the instrument after use. Remove the battery if
the instrument is to be stored and will not be in use for a
long period.
● Do not expose the instrument to direct sunlight, high
temperature and humidity or dewfall.
● Use a cloth dipped in water or neutral detergent for
cleaning the instrument. Do not use abrasives or
solvents.

voltage over 600V exists.
●Keep your fingers and hands behind the barrier
during measurement.

NOTE
● Beep sounds when the instrument switches the ranges
from 60V to 600V.
● If the connection is reversed, the “ － “ mark will be
displayed on the LCD. (DCV measurement).
● The LCD shows some digits at the ACV or the DCV
range even while the test leads are open. And, it may
show some digits instead of 0 even if the test leads are
shorted. However, these phenomena don’t affect
measurement results.
4.Resistance(Continuity)Measurement
WARNING
Never use the instrument on an energized circuit.

” “ appears on the LCD.
Beep 60Ω or less.
NOTE
● LCD shows ”OL” when the test leads are open.
● Even if the test leads are shorted, the indicated values
may not be”0”. But this is because of the resistance of
test leads and not a failure. High resistance
measurement and capacitive components may fluctuate
readings.
5. Capacitance Measurement
WARNING
Never use the instrument on an energized circuit.
Discharge the capacitor before measurement.
Press the RELΔ key before starting a measurement and
adjust the displayed value to “0.000nF”.
Capacitance
NOTE
Measurement time at 600µF range is a bit long since the
reading is updated once in approx 5 sec.
6. Other Functions
● REL Function
Press the RELΔ key to enable this function and store the
measured value to display the differences between the
stored value and the values measured in further tests.
(at any functions other than Continuity) The measurement range will be fixed when the REL function is
enabled, and the measuring range will be between the
initial value and the full scale value. (except for
Capacitance)
Press the RELΔ Key again to release the stored value.
“ Δ ” symbol appears
when RELΔ Key is pressed.
● Low battery indication
“ ” symbol appears
at 2.3±0.1V or less.
● Sleep Function
Automatically powers off the instrument in about 15 min
after the last switch operation.
Buzzer beeps five times one minute before entering into
the Sleep mode, and also one time just before
entering into the mode.

Push RELΔ key.
” Δ “ appears on the LCD.
● This instrument can make measurements while one test
lead is left in place. So you can perform a test with
checking the readings.
7. Battery Replacement
WARNING
● Replace the battery when the " " mark- low battery
voltage warning- appears on the LCD.
Otherwise, precise measurement cannot be made. If the
battery is completely exhausted, the LCD goes blank
without showing the " " mark.
● Do not try to replace the battery if the surface of the
instrument is wet.
● Power off the instrument before opening the case for
battery replacement.
CAUTION
● Install a battery in correct polarity as indicated in the
Battery Compartment.
(1) Set the Function Switch to "OFF" position.
(2) Remove the Hard case.
1. Remove the test leads from the holder
2. Open and hold the Hard case cover about 90-degree,
and then push the instrument through the hole on the
back side of the Hard case.

(3) Loosen the screw on the back side of the instrument
and remove the case.
(4) Replace the battery with a new one (CR2032)
observing the correct polarity.
