20℃ (68℉)~300℃ (572℉)● 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 theaverage of square of alternating current or voltage
values. Many clamp meters using a conventionalre c t i f y i n g c i rc u i t h a v e " R M S " s c a l e s f o r A C
measurement. The scales are, however, actuallycalibrated in terms of the effective value of a sine
wave though the clamp meter is responding to theaverage value. The calibration is done with aconversion factor of 1.111 for sine wave, which isfound by dividing the effective value by the averagevalue. These instruments are therefore in error if the
input voltage or current has some other shape thansine wave.

● Do not try to replace the batteries if the surface of

the instrument is wet.

● Disconnect all the cords and cables from theobject under test and power off the instrument
before opening the Battery Cover for Battery
replacement.
● Stop using the test lead if the outer jacket isdamaged and the inner metal or color jacket is
exposed.
# CAUTION● Set the Function Switch to an appropriate position

before starting measurement.

● Firmly insert the test leads.

● Disconnect the test leads from the instrument for

current measurement.

● Do not expose the instrument to the direct sun,high temperature and humidity or dewfall.

● Altitude 2000m or less. Appropriate operating

temperature is within 0℃ and 40℃.

● This instrument isn't dust & water proofed. Keepaway 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 thebatteries.
● Use a cloth dipped in water or neutral detergent
for cleaning the instrument. Do not use abrasives
or solvents.
Measurement Category
To ensure safe operation of measuring instruments,
IEC 61010 establishes safety standards for various
electrical environments, categorized as O to CAT IV,
and called measurement categories. Higher-numberedcategories correspond to electrical environments withgreater momentary energy, so a measuring instrument
designed for CAT III environments can endure greater
momentary energy than one designed for CAT II.
O: Circuits which are not directly connected tothe mains power supply.
CAT II : 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 tooutlets.
CAT IV : The circuit from the service drop to theservice entrance, and to the power meterand primary over-current protection device(distribution panel).

● CF (Crest Factor) is found by dividing the peakvalue by the effective value.
Examples: Sine wave: CF=1.414
Square wave with a 1: 9 duty ratio: CF=3

4. Preparation for measurement

4-1. Checking Battery Voltage
Set the Function Switch to any position other than"OFF". When the display is clear without "BATT" mark,showing battery voltage is enough. When the display isblank or "BATT" mark is indicated, replace the batteries
according to Section 7, Battery Replacement.
# CAUTION
T h e S l e e p f e a t u re a u t o m a t i c a l l y p o w e r s t h e
instrument off in about 15 min after the last switch or
key operation. Therefore, the display may be blankeven with the Function Switch set to a position otherthan "OFF". To operate the instrument in this case,turn the switch back to the "OFF" position, then to
any other position. Replace the batteries if nothing
was displayed after above operations.
4-2. Checking Switch Setting & Operation
Confirm the Function Switch is set to the correctp o s i t i o n , t h e i n s t r u m e n t i s s e t t o t h e c o r re c tmeasurement mode,and the Data hold function isdisabled. Otherwise,desired measurement cannot be
made.

5. Measurement
5-1. AC Current Measurement# DANGER● Never make measurement on a circuit in which

voltage over AC600V exists to avoid getting
electrical shock.
● Transformer jaw tips are designed not to short thecircuit under test. If equipment under test has
exposed conductive parts, however, extra precaution should be taken to minimize the possibilityof shorting.
● Do not make measurement with the Battery Coverremoved.
● Disconnect the test leads from the instrument for
current measurement.
● Keep your fingers and hands behind the barrier
during measurement.
(1) Set the Function Switch to "600A" or "1000A"
position.

then take the reading on the display. Pressing the"Hz/DUTY" Key switches the indication in following
sequence.
AC Current ⇨ Hz ⇨ DUTY
Hz/DUTY Function requires 50A or more at AC600A
Range and 350A or more at AC1000A range.
# CAUTION● Max conductor size for KEW2046R is approx dia.

33mm and for KEW2056R is approx dia. 40mm.
During current measurement, keep thetransformer jaws fully closed. Other wise, accurate
measurements cannot be taken.

position. AC has been selected by default; press
the SELECT key, when AC has been selected, tochange it to DC. (only 600A is available on
KEW2046R) DC mark is displayed at the upper left
on the display.
(2) With the transformer jaws closed and without
clamping them onto the conductor, press the"ZERO" key to zero adjust the display. (△ mark is
displayed at the upper right on the display.)

6-2. HOLD Key(1) Data Hold Function
This is a function to freeze the measured value on
the display. Press the "HOLD" key to freeze thereading.
The reading will be held regardless of subsequentvariation in input. "H" is indicated on the upper left
corner of the display while the instrument is in the
Data Hold mode. To exit Data Hold mode, press
the "HOLD" key again.

6-3. NCV Function
Red LED on the upper area on the Panel lights up at
All functions except for OFF when electric fieldexceeding 100V is detected by the sensor installedin the Jaws.
It indicates a presence of voltage in an electricalcircuit or equipment without touching them.
NCV Sensor can detect electricalf i e l d o n l y f ro m t h e d i re c t i o nindicated in the right figure.
Put the fixed element (left side)closer to the conductor under test.
Detection against in-wall outlet is
impossible.
# DANGER● The LED may not light up due to installation

condition of electrical circuit or equipment. Never
touch the circuit under test to avoid possible danger
even if the LED for NCV doesn't light up.
● Check the functionality of LED on a well-known
power supply prior to measurement. When the
LED doesn't light up, do not make measurement.
● NCV indication is affected by external voltage,
how to hold or place the instrument.
● Keep your fingers and hands behind the barrier
during measurement.
6-4. MIN/MAX Function# CAUTION● Held readings are released when Sleep Functionis activated while the instrument is in the Data
Hold mode.
● SELECT, ZERO, Hz/DUTY keys are disabled
while MIN/MAX Function is being activated.

(3) Press the trigger to open the transformer jaws andclamp them onto the one conductor under test, theconductor should be at the center of the jaws, thentake the reading on the display.
(4) S e t t h e F u n c t i o n S w i t c h t o a n a p p ro p r i a t e
position according to current under test.
(5) Pressing the "ZERO" key again releases "ZERO"
function. (△mark at the upper right on the display
disappears.)# CAUTION● When the current flows from the upside (thedisplay side) to the underside of the instrument,
the polarity of the reading is positive and viceversa.
