● Never make measurements under the circumstances
exceeding the designed measurement category and therated voltage of the instrument.
● Do not attempt to make measurement in the presence offlammable 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 yourhand 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.
● Protective figerguard on the test leads provide protection
to keep your fingers and hands from touching an object
under test. Keep your fingers and hands behind theprotective fingerguard during measurement.

WARNING● Never attempt to make measurement if any abnormal
conditions, such as broken case and exposed metalparts 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 try to replace the battery if the surface of the

● 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 tothe instrument. For repair or re-calibration, return theinstrument to your local KYORITSU distributor.
●Ensure that the test lead is disconnected from the object
under test, and that the instrument is powered off when
opening the battery compartment cover for battery
replacement.
●Stop using the test lead if the outer jacket is damaged andthe inner metal or color jacket is exposed.

CAUTION● Use of this instrument is limited to domestic, commercial
and light industry applications. Strong electromagnetic
interference or strong magnetic fields, generated bylarge 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 awayfrom dust and water.
● Do not pull or twist the test leads to prevent the risk ofdamage.
● Power off the instrument after use. Remove the battery if
the instrument is to be stored and will not be in use for along period.
● Do not expose the instrument to direct sunlight, hightemperature and humidity or dewfall.
● Use a cloth dipped in water or neutral detergent forcleaning the instrument. Do not use abrasives orsolvents.

This instrument is basically designed for CAT II 600V, but
the cap for CAT III 300V is supplied with.

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 oftest leads and not a failure. High resistancemeasurement and capacitive components may fluctuatereadings.

3. ACV/DCV Measurement●Never make measurement on a circuit in which
voltage over 600V exists.
●Keep your fingers and hands behind the protective
figerguard during measurement.

● This instrument can make measurements while one test
lead is left in place. So you can perform a test withchecking the readings.

Temperature: 23 ± 5°C, Humidity: 45 - 75%

WARNING

Never use the instrument on an energized circuit.
Discharge the capacitor before measurement.
Press the RELΔ key before starting a measurement andadjust the displayed value to “0.000nF”.

● Replace the battery when the "" mark- low battery
voltage warning- appears on the LCD.
Otherwise, precise measurement cannot be made. If thebattery is completely exhausted, the LCD goes blankwithout showing the "" mark.
● Do not try to replace the battery if the surface of theinstrument is wet.
● Power off the instrument before opening the case forbattery replacement.

Red(+)CAUTION

Push RELΔ key.
” Δ “ appears on the LCD.

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 areshorted. However, these phenomena don’t affectmeasurement results.

4.Resistance(Continuity)Measurement

WARNING

Never use the instrument on an energized circuit.

NOTE

Measurement time at 600µF range is a bit long since thereading is updated once in approx 5 sec.

6. Other Functions● REL Function
Press the RELΔ key to enable this function and store themeasured value to display the differences between thestored value and the values measured in further tests.
(at any functions other than Continuity) The measurement range will be fixed when the REL function isenabled, and the measuring range will be between theinitial value and the full scale value. (except forCapacitance)
Press the RELΔ Key again to release the stored value.
“ Δ ” symbol appears
