Electronic Measuring apparatus, and delivered in

the best condition after passed the inspection. This

instruction manual contains warnings and safety

rules which must be observed by the user to ensure

safe operation of the instrument and retain it in safe

condition.

Therefore, read through these operating instructions

before using the instrument.

WARNING

●

contained in this manual before using the

instrument.

●

Keep the manual at hand to enable quick

reference whenever necessary.

●

The instrument is to be used only in its intended

applications.

●

U n d e r s t a n d a nd f o l l o w a l l the s a f e t y

instructions contained in the manual.

●

It is essential that the above instructions are

adhered to.

●

Failure to follow the above instructions may

cause injury, instrument damage and/or damage

to equipment under test.

The symbol

AC & DC

DANGER

●

Never make measurement on a circuit in which

voltage over AC600V 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.

●

Transformer jaw tips are designed not to short

the circuit under test. If equipment under test

has exposed conductive parts, however, extra

precaution should be taken to minimize the

possibility of shorting.

●

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 o pen the B atter y cover d uring a

measurement.

●

The instrument is to be used only in its intended

applications or conditions. Otherwise, safety

functions equipped with the instrument doesn

’

work, and instrument damage or serious personal

injury may be caused.

WARNING

●

Never attempt to make measurement if any

abnormal conditions, such as broken case

and exposed metal parts are found on the

instrument.

●

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.

●

Do not try to replace the batteries if the

surface of the instrument is wet.

●

Disconnect all the cords and cables from the

object under test and power off the instrument

before opening the Battery Cover for Battery

replacement.

●

Verify proper operation on a known source

before use or taking action as a result of the

indication of the instrument.

●

Use appropriate personal protective equipment

such as insulating gloves, Insulating boots, and

safety glasses.

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. 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.

●

Use a cloth dippe d i n water or neu tr al

detergent for cleaning the instrument. Do not

use abrasives or solvents.

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-

numbere d categories corr espond to electrical

environments with greater momentary energy,

so a measuring instrument designed for 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

: 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).

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 Sleep feature automatically powers the

instrument off in about 15 min after the 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,

or press any key. Replace the batteries if nothing

was displayed after above operations.

4-2. Checking Switch Setting & Operation

Confirm the Function Switch is set to the correct

po sition, th e i nstrument is set to the correct

measurement mode,

and the Data hold function is disabled. 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

the circuit under test. If equipment under test

has exposed conductive parts, however, extra

precaution should be taken to minimize the

possibility of shorting.

●

Do not make measurement with the Battery

Cover removed.

●

Disconnect the test leads from the instrument for

current measurement.

(1) Set the Function Switch to "

600A

" or "

1000A

position. (on KEW2040, only "600A" is available)

AC has been selected by default; press the SELECT

key, when DC has been selected, to change it to

AC. AC mark is displayed at the upper left on the

display. (KEW2055 only)

(2) Press the trigger to open the transformer jaws

and clamp them onto the one conductor under test,

then take the reading on the display. Pressing the

Hz/DUTY

" Key switches the indication in following

sequence.

AC Current

⇨

DUTY

Hz/DUTY

Function requires 50A or more at AC600A

Range and 350A or more at AC1000A range.

CAUTION

●

Max conductor size for KEW2040 is approx dia.

33mm and for KEW2055 is approx dia. 40mm.

During current measurement, keep the trans

former jaws fully closed. Other wise, accurate

measurements cannot be taken.

5-2. DC Current Measurement (KEW2055 only)

DANGER

●

Never make measurement on a circuit in which

voltage over DC600V exists to avoid getting

electrical shock.

●

Do not make measurement with the Battery

Cover removed.

(1) Set the Function Switch to "

600A

" or "

1000A

position. AC has been selected by default; press

the SELECT key, when AC has been selected, to

change it to DC.
