1. Safety Warnings
This instrument has been designed, manufactured and
tested according to IEC 61010: Safety requirements for
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 indicat
ed on the instrument means that
the user must refer to the related parts in the manual for
safe operation of the instrument. It is essential to read the
instructions wherever the symbol appears in the
manual.
DANGER is reserved for conditions and actions that
are likely to cause serious or fatal injury.
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
O
Circuits 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).
Current measurement section of this instrument is
designed for CAT IV 300V / CAT III 600V and Voltage
measurement section is for CAT III 300V / CAT II 600V
respectively.
Test leads 7107A with the Cap is designed for CAT IV
600V / CAT III 1000V and without the Cap is 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
taking action as a result of the indication of the instrument.
● Firmly attach the Caps to the test leads when
performing measurements at CAT III or higher test
environment.
When KEW2200R 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 while the test leads are
being connected.
● Do not install substitute parts or make any modification to
the instrument. For repair or re-calibration, return the
instrument to your local distributor from where it was
purchased.
CAUTION
● Use of this instrument is limited to domestic, commercial
and light industry applications. If equipments generating
strong electromagnetic interference or strong magnetic
fields due to large currents exist nearly, malfunctions of
the instrument may be caused.
● Set the Function Switch to an appropriate position before
starting measurement.
● Firmly insert the test leads.
● The LCD shows some readings at the ACV and the DCV
ranges even while the test leads are open. And, it may
show some digits instead of 0 when short-circuiting the
test leads. However, these phenomena don't affect
measurement results.
● This instrument isn't dust & water proofed. Keep away
from dust and water.
● Be sure to power off the instrument after use. When the
instrument will not be in use for a long period, place it in
storage after removing the batteries.
● Do not expose the instrument to the direct sun, 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.
