1. Safety Warnings

This instrument has been designed, manufactured and tested according
to following standards, and delivered in the best condition after passing
quality control tests.

● IEC61010-1 Measurement Category CAT.III 300V / CAT.ll 400V

Pollution degree 2

● IEC61010-031

● IEC61557-1, 6

● IEC60529 IP54

This instruction manual contains warnings and safety rules which
have to be observed by the user to ensure safe operation of the
instrument and to maintain it in safe condition. Therefore, read
through these operating instructions before using the instrument.

DANGER

● Read through and understand the instructions 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.

● 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 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 actions that are likely to

cause serious or fatal injury.

WARNING is reserved for conditions and actions that can cause

serious or fatal injury.

CAUTION is reserved for conditions and actions that can cause

injury or instrument damage.

DANGER

● This instrument is designed to measure the earth-to-line voltage
90 ~ 264V and the line-to-line voltage up to 440V (50/60Hz). Do not
exceed the maximum allowable input of any measuring range.

● 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.

● Keep your fingers behind the safety barrier on the test leads.

● Set the Function Switch to any desirable Range before making

a measurement. Do not power on the instrument with it being
connected to the live circuit.

● Never attempt to use the instrument if its surface or your hand are
wet.

● Never open the Battery Cover during a measurement.

● Verify proper operation on a known source before use or taking

action as a result of the indication.

WARNING

● Never attempt to make any measurement if any abnormal
conditions, such as a broken cover or exposed metal parts are
present on the Instrument and test leads.

● Do not install substitute parts or make any modification to the
instrument. Return the instrument to your local KYORITSU
distributor for repair or re-calibration in case of suspected faulty
operation.

● Set the Function Switch to the OFF position when removing the
Battery Cover for battery replacement.

● If the overheat symbol “ ” appears on the display, disconnect the
instrument from the measuring point and allow to cool down.

CAUTION

● Firmly insert the plugs of test leads to the appropriate terminals.

● Set the Function switch to the OFF position after use, and remove

the batteries if the instrument is to be stored and will not be in use
for a long period.

● Use a damp cloth with neutral detergent for cleaning the instrument.
Do not use abrasives or solvents.

● Do not store the instrument if it is wet.

2. Procedure of removing Cover

KEW5410 has a dedicated Cover to protect against impacts from the
outside and prevent the operation part, the LCD and the Connector Block
from becoming dirty. The Cover can be detached and put on the
backside of the main body during measurement.

2-1 Method of removing the Cover

Slide and pull the Cover
in the direction of an arrow.

Fig.1

2-2 Method of storing the Cover

Turn the Cover, slide and
push it in the direction of
arrow.

3. Feature

This instrument is a digital RCD Tester to measure the trip time and trip
out current of RCDs. It also equips the function to measure the voltage.

● Measurement of RCD trip time
Conducting testing of rated residual non-operating currents at x 1/2
Range, measuring RCD trip time at x1 and x5 Ranges.

● Measurement of trip out current
Measuring trip out current by varying current automatically.

● Remote Test
Enabling a user to hold the Test Leads with his both hands by
locking the Test Button.

● Voltage Measurement
Carrying out a constant measurement of voltage in the stand-by mode
at each Range.

● Auto-detection of Contact voltage
Detecting the voltage to earth of Earth electrodes or Protective
conductors during RCD test – when applying test currents – at
measurement using EARTH in order to prevent electrical shocks
caused by the damaged earth.
Measurement will be ceased at AC50V or more.

● Dust- and Water-proof
Dust- and Water-proof construction (designed to IEC60529 IP54)

● Backlight
Facilitating working at dimly illuminated locations.
