● 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 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

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
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.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 measurement on a circuit in which
voltage over AC/DC600V exists.
● 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.
● 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 KEW2200 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.
7. Battery Replacement
WARNING
● Replace the batteries when a Low Battery
Voltage warning " " mark(< 2.3±0.15V) is
indicated on the LCD. Otherwise, precise
measurement cannot be made. Note that when
the battery is completely exhausted, the LCD
goes blank without showing " " mark.
● Do not try to replace the batteries if the surface of
the instrument is wet.
● Disconnect the test leads from the object under
test and power off the instrument before opening
the Battery Compartment Cover for Battery
replacement.
CAUTION
● Do not mix old and new batteries.
● Install batteries in correct polarity as indicated in
the Battery Compartment.
(1) Set the Function Switch to "OFF" position.
(2) Unscrew and remove the Battery Compartment
Cover on the bottom of the instrument.
(3) Replace the batteries observing correct polarity.
Use new two R03/LR03 (AAA) 1.5V batteries.
(4) Install the Battery Compartment and tighten the
screws.
