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

[Effective Value (RMS) ]
Most alternating currents and voltages are expressed in
effective values, which are also referred to as RMS
(Root-Mean-Square) values.
The effective value is the square root of the average of
square of alternating current or voltage values. Many
clamp meters using a conventional rectifying circuit have
"RMS" scales for AC measurement. The scales are,
however, actually calibrated in terms of the effective
value of a sine wave though the clamp meter is
responding to the average value. The calibration is done
with a conversion factor of 1.111 for sine wave, which is
found by dividing the effective value by the average
value. These instruments are therefore in error if the
input voltage or current has some other shape than sine
wave.
[ CF (Crest Factor) ]
CF (Crest Factor) is found by dividing the peak value by
the effective value.
Examples: Sine wave: CF=1.414
Square wave with a 1: 9 duty ratio: CF=3

4. ACA Measurement
DANGER
Never measure current while the test leads are inserted
into the V/Ω and/or COM Terminals.
Press the trigger to open the Current Sensor and clamp the
one conductor (Dia. 33mm max.) under test.
NOTE
Measurement accuracy is guaranteed
when the measured object is
placed at the center (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).
5. ACV/DCV Measurement
DANGER
Never make measurement on a circuit in which voltage
over 600V exists.
NOTE
If the connection is reversed, the LCD indicates the
“－“ mark (DCV measurement).
6.Resistance(Continuity)Measurement
WARNING
Never use the instrument on an energized circuit.
NOTE Beep less than 50±30Ω.
LCD indicates ”OL” when the test leads are open.
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 Cover
and tighten the screws.
