Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instruments,
IEC61010 establishes safety standards for various
electrical environments, categorized as CAT.Ⅰ to
CAT.Ⅳ, and called measurement categories.
Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a
m e a su r i n g in s t r u m e n t d e s ig n e d f o r CAT. Ⅲ
environments can endure greater momentary energy
than one designed for CAT.Ⅱ.
CAT.Ⅰ: Secondary electrical circuits connected to an
AC electrical outlet through a transformer or
similar device.
CAT.Ⅱ: Pr ima ry electr ica l circuits of e qui pme nt
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: Th e circuit fro m the ser vice drop t o the
service entrance, and to the power meter
and primary over current protection device
(distribution panel).

Effective Value (RMS)
Mo st # alte rnat ing cu r re n ts and v o lta ges are
ex p res s e d in ef fecti v e values , w h ich are al s o
ref erre d to as RMS (Root-Mean-S qu are) values.
The effect i v e v a l u e is the square ro o t o f the
average of square of alternating current or voltage
values. Many clamp meters using a c onventional
recti f y i n g circu i t ha v e "R M S" sc a l e s fo r AC
measu rement. The s cales are, however, actual ly
calibrated in terms of the effective value of a sine
wave though the clamp meter is responding to the
av e r age val u e . The calib r atio n is don e w i t h 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) 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. 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 is
blank or "BATT" mark is indicated, replace the batteries
according to Section 7, Battery Replacement.
# CAUTION
The Slee p f e a t u r e au t o m a t i cal l y po w e r s th e
instrument off in about 15 min after t
he last switch or
key operation. Therefore, the display may be blank
even with the Function Switch set to a position other
than "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
Confi rm the Function Switch is set to the correct
position, t h e instr u m e n t is set t
o th e co r r e c t
measurement mode,and th e Data hold function is
disabled. Otherwise,desired measurement cannot be
made.

(2) Connect the red test lead to V/Ω terminal and the
black test lead to COM terminal.
(3) Connect the test leads to the both ends of the
capacitor under test.
(4) Take the reading on the display.
5-6 Temperature Measurement
(1) Set the Function Switch to "℃/℉" position.
(2) Connect the K-type Temperature Probe (Optional
Accessories) to the input terminal. Positive (+) side
of Probe should be connected to V/Ω.
(3) Co n t a c t th
e Se n s o r (me t a l pa r t ) of K- t y p e
Temperature Probe to the object under test. Take
the reading on the display. Positive ( +) side o f
Probe should be connected to V/Ω.
# WARNING
●
Ne v er conn e ct the Tem pera t ure P robe t o a n
energized circuit.
# CAUTION
●
Room temperature is indicated on the LCD when
setting the Function Switch to "℃ /℉" position. In
cas e that "OL" or an ythin g othe r than roo m
temperature
is indicated, something may wrong
with the instrument. Stop the use of instrument
immediately.
●
There may be a break in Probe when indication
isn' t chang ed i f Senso r (meta l part) o f K- typ e
Temperature Probe is contacted with the object
under test.
6. Other functions
6-1. Sleep Function
(1) Thi s is a func t i o n to pre v e n t th e inst r u m e nt
from being left powered on in order to conserve
battery life. This function causes
the instrument
to enter Sleep mode about 15 minutes after the
last key operation. To exit the Sleep mode, turn
the Function switch to "OFF", then to any other
position.
(2) Sleep Function is disabled when;
M I N / M A X o r P E A K F u n c t i on i s s e le c t ed .
Continuous measurement is made with the Sleep
Fun c t i o n be i n g disa b l e d . To activ a t e Slee p
Fu nctio n again, dis able th e MIN /MAX or P EAK
Function.
# CAUTION
●
The instrument consumes small amount of battery
power in the Sleep mode. Set the Function Switch
to the OFF position after use.
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 the
reading.
The reading will be held regardless of subsequent
variation in input. "H" is indicated on the upper left
corner of the display while the ins
trument is in the
Data Hold mode. To exit Data Hold mode, press
the "HOLD" key again.
# CAUTION
●
Held readings are released when Sleep Function
is activated while the instrument is in the Data Hold
mode.
(2) Backlight ON/OFF
Pressing the HOLD key 2 sec or more lights up the
Backlight. Pressing the HOLD key 2 sec or more
again turns off the Backlight.
6-3. NCV Function
Red LED on the upper area on the Panel lights up at
Al l fun ctio ns ex cept for OF F when elec tri c fiel d
exceeding 100V is detected by t
he sensor installed
in the Jaws.
It indicat es a p resence of vo ltage in an electrical
ci rc u i t or equi p m e n t wi t h o u t
touching them.
NCV Sensor can detect electrical
fi e l d on ly fr o m th e direc t i o n
indicated in the right figure.
Put the fixed element ( le ft side)
closer to the conductor under test.
Detection against in-wall outlet is
impossible.
# DANGER
●
Th e LED may no t l ight u p d ue to ins t all a tio n
condit
ion of electrical circuit or equipment. Never
touch the circu it under test to avoid po ssibl e
danger even if the LED for NCV doesn't light up.
●
Check th e functionalit y of LED on a well-known
power supply prior to measurement. When the
LED doesn't light up, do not make measurement.
●
NCV indicati on is affected by external voltage,
how to hold or place the instrument.
6-4. MIN/MAX Function
# CAUTION
●
Held readings are released when Sleep Function
is activated while the instrument i s in the Data
Hold mode.
●
SEL E C T, ZE R O , H z / D U TY ke y s ar e di s a b led
while MIN/MAX Function is being activated.
(1) AC/DC Current Range (600A only on KEW2046R)
Pr essi n g the MIN/M A X Key at 600A & 1000A
Function enables min or max value measurement.
(4) Press the PEAK Ke y at least 2 sec to res et the
indication or release PEAK Function.
Bu z z e r so u n d s t w i c e , a n d th e Fu n c t i o n is
released.
# CAUTION
●
PEAK indication for Crest value is up to 1500A.
Er ro r ind ication is g ive n when excee din g thi s
range value.
●
Sleep Function is disabled when PEAK Function is
selected. Care should be taken when performing
continuous measurement.
6-7. Over-flow indication
When the input
exc eeds the meas ur ing range at
eac h Functi o n other than Voltag e ,1000A and
Temperature Range "OL" or "-OL" is indicated on the
display.
7. Battery Replacement
# WARNING
●
To avoid electrical hazard, set the Function Switch
to " OFF" a nd re mov e the tes t lea ds from the
instrument before trying to replace batteries.
# CAUTION
●
Do not mix old and new batteries.
●
Install batteries in correct polarity as indicated in
the Battery Compartment.
Replace the batteries when a Low Battery Vol tage
warn ing "BAT T" m ark is in dicat ed o n the displ ay.
Note that when the battery is completely exhausted,
the display blanks without "BATT" mark shown.
(1) Set the Function Switch to "OFF" position.
(2) Unscrew and remove the Battery Comp ar tment
Cover on the bottom of the instrument.
(3) Replace the batteries observing correct polarity.
Use new R03 (AAA)
or LR03 / 1.5V batteries.
(4) Install the Battery Compartment and tighten the
screws.
8. Maintenance
●
Cleaning
Use a cloth dipped in water or neutral detergent for
cleaning the instrument.
Do not use ab r asiv e s or s o lven t s. Other w ise,
instrument get damaged, deformed or discolored.
