● 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.
