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

Marks listed below are used on this instrument.

User mus t 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.

kewtechcorp.com

• 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

kewtechcorp.com

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.

•

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 slightly damp cloth 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 screw.
