Measurement Category

O Circuits which are not directly connected to the mains
Barrier of Test Leads
Cappower supply.

CAT II Primary electrical circuits of equipment connectedto 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).
This instrument is designed for CAT IV 300V / CAT III
600V. Test leads M-7066A with the supplied cap aredesigned for CAT IV 600V / CAT III 1000V and without
the caps are for CAT II 1000V.

NOTE● The LCD shows some digits at the ACV and the DCV
ranges even while the test leads are open. In addition,
the LCD shows some digits instead of 0 when shortcircuiting the test leads. However, these phenomena
don’t affect measurement results.

DANGER● Never make measurements under the circumstances
exceed the designed measurement category and therated voltage of the instrument and the test leads.
● 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 Battery cover during a measurement.
● To avoid electrical shock by touching the equipment
under test or its surroundings, be sure to wear insulated
protective gear.
● Never measure current while the test leads are inserted
into the input terminals.
● Test leads to be used for voltage measurements shall berated as appropriate for Measurement Category III or IV
according to IEC 61010-031 and shall have a voltage
rating of 600V or higher.
● Barriers on the instrument body and the test leads
provide protection to keep your fingers and hands fromtouching an object under test. Keep your fingers andhands behind the barriers 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 or higher test
environments. When KEW2007R and the test leads
are combined and used together, whichever is lower
category & voltage to earth either of them belong tois applied.
● Do not rotate the Function Switch if the instrument andthe equipment under test are connected.
● Do not install substitute parts or make any modification to
the instrument. For repair or re-calibration, return theinstrument 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 bylarge currents, may cause malfunction of the instrument.
● Connect the test leads to the terminals firmly.
● This instrument isn’t water proofed. Keep away fromwater.
● Do not pull or twist the test leads to prevent the risk ofdamage.
● Power off the instrument after use. Remove batteries if
the instrument is to be stored and will not be in use for along period.
● Do not expose the instrument to the direct sunlight, hightemperature and humidity or dewfall.
● Use a cloth dipped in water or neutral detergent forcleaning the instrument. Do not use abrasives or solvents.
