Electronic measuring apparatus, and delivered in the best

condition after passed the inspection. 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 the instructions contained

in this manual before using the instrument.

● Keep the manual at hand 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.

● It is essential that the above instructions are adhered to.

Failure to follow the above instructions may impair the

protection provided by the instrument and test leads, and

may cause injury, instrument damage and/or damage to

equipment under test.

The symbol indicated on the instrument means that the

WARNING is reserved for conditions and actions that

can cause serious or fatal injury.

CAUTION is reserved for conditions and actions that

can cause injury or instrument damage.

● Marks listed below are used on this instrument.

User must refer to the manual.

Instrument with double or reinforced insulation

Indicates that this instrument can clamp on

bare conductors when measuring a voltage

corresponding to the applicable measurement

category, which is marked next to this symbol.

AC DC Ground (Earth)

This instrument is subject to WEEE Directive

(2002/96/EC). Please contact our dealer near

you at disposal.

Measurement Category

OCircuits 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 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 are

designed for CAT IV 600V / CAT III 1000V and without

the caps are for CAT II 1000V.

DANGER

● Never make measurements under the circumstances

exceed the designed measurement category and the

rated voltage of the instrument and the test leads.

● 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 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 be

rated 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 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 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 to

is applied.

● 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.

● Connect the test leads to the terminals firmly.

● This instrument isn’t water proofed. Keep away from

water.

● Do not pull or twist the test leads to prevent the risk of

damage.

● Power off the instrument after use. Remove batteries if

the instrument is to be stored and will not be in use for a

long period.

● Do not expose the instrument to the 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.

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 short-

circuiting the test leads. However, these phenomena

don’t affect measurement results.
