NOTE
Measurement accuracy is guaranteed when the
measured object is placed at the centre (zone A)
of the Current Sensor. In zone B, 4% of tolerance
should be added to the specified accuracy. In
zone C, measured values should be considered as
reference values (Accuracy is not guaranteed).

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.
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.

• 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 the KEW2200 and the test leads
are combined and used together,
whichever is the lowest category &
voltage to earth specification applies.
• 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 equipment generating strong
electromagnetic Interference or strong
magnetic fields due to large currents exist
nearby, the instrument may not work correctly.
•Set the Function Switch to an appropriate
position before starting measurement.
•Firmly insert the test leads.
•The LCD may show some readings at the
ACV and the DCV ranges even while the test
leads are open. And, it may show some digits

7. Battery Replacement
CAUTION
• Do not mix old and new batteries.
• Install batteries in correct polarity as
indicated in the Battery Compartment.

(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 screw.
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.
instead of 0 when short-circuiting the test
leads. However, these phenomena doesn’t
affect measurement results.
•This instrument isn’t dust & waterproof.
•Keep away from dust and water.
