# 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

● Never make measurement on a circuit in the following categories;

Measurement category IV(CAT IV):over 600V

Measurement category III(CAT III):over 1000V

● 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 ranges.

# WARNING

● Never attempt to make measurement if any abnormal conditions,

such as broken case and exposed metal parts are found on the

instrument or cables.

● Verify proper operation on a known source before starting to use

the instrument or taking action as a result of the indication of the

instrument.

● Do not install substitute parts or make any modifications to the

instrument. Return the instrument to your local KYORITSU

distributor for repair or re-calibration in case of suspected faulty

operation.

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

is wet.

● Ensure that the Clamp sensor is disconnected from the object

under test, and that the instrument is powered off when opening

the Battery compartment cover for battery replacement.

# CAUTION

● This instrument is designed for residential, commercial or light

industry applications. Accurate results may not be obtained if

equipments generating strong electromagnetic interferences

or strong magnetic fields due to large currents exist in the

neighborhood.

● Set the Function switch to the appropriate position before starting

measurement.

●  This instrument isn t water proofed. Keep away from water.

● Be sure to power off the instrument after use. Remove the

batteries if the instrument is to be stored and will not be in use for

a long period.

● Do no t e x p o s e t h e ins t rume n t to d i r e ct sun l i g h t , h i g h

temperatures, humidity or dew.

● Use a damp cloth with water or neutral detergent for cleaning the

instrument. Do not use abrasives or solvents.

● Marks listed below are used on this instrument.

#User must refer to the explanations in the instruction

manual.

Instrument with double or reinforced insulation.

Must wear insulated gears such as a pair of rubber gloves

when connecting / disconnecting the sensor to / from live

conductors.

Crossed-out wheel bin symbol (according to WEEE

Directive: 2002/96/EC) indicating that this electrical product

may not be treated as household waste, but that it must be

collected and treated separately.

● Measurement categories(Over-voltage categories)

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-numbered categories correspond 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.

O : Circuits which are not directly connected to the 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 to outlets.

CAT IV : The circuit from the service drop to the service entrance, and

to the power meter and primary overcurrent protection device

(distribution panel).

5. Getting started

(1) Checking battery voltage

Set the Function switch to any position other than the OFF position.

When the indications on the display are clearly legible and the

" " mark is not on, the battery voltage is OK.

If the display is blank or " " mark is on, replace the batteries

according to Section 8: Battery Replacement.

# CAUTION

● When the instrument is left powered on, the Auto-power-off

function automatically shuts the power off; the display will be

blank even if the Function switch is set to any positions other than

the OFF position in this state.

To power on the instrument, rotate the Function switch or press

any of the buttons. If the display is still blank, the batteries are

exhausted.

Replace the batteries with the new ones.

(2) Checking Function switch position

Set the Function switch to the appropriate range according to the

measurement purpose. Confirm that the Data hold function is not

activating.

6. Operating instructions

# DANGER

● Never make measurement on a circuit in the following categories;

CAT IV over 600V

CAT III over 1000V

● Never open the Battery compartment cover while making

measurement.

● To avoid getting electrical shock by touching the equipment under

test or its surroundings, be sure to wear insulated protective

gears.

(1) Disconnect the Joint

connector according to

the illustration to the right.

(2) Clamp onto one conductor under the test, and re-connect the Joint

connector. Hold the conductor at the center of the Clamp sensor.

(3) Confirm that the Joint connector on the Clamp sensor is firmly

connected.

Note

● Jointed part of the Clamp sensor may be disconnected if excessive

force is applied to.

● Clamp onto one conductor only; measurements cannot be made

when clamping single-phase (2-wire) or three-phase (3-wire) at the

same time.

7. Other functions

7-1 Auto-power-off function

This function is to prevent the battery from being exhausted by the

instrument being unintentionally left on.

The instrument automatically shifts to the power-off state about 15

min after the last Function switch or other switch operation.

To exit from the Auto-power-off status, press any button or set the

Function switch to the OFF position once, and then set it to the

desired range.

  mark is displayed on the LCD when the Auto-power-off

function is enabled.

[To cancel the Auto-power-off function]

To cancel the Auto-power-off function, hold down the Data hold

button and turn the Function switch from OFF position to any other

position.

While this function is disabled,   mark is not displayed on the

LCD.

[To enable the Auto-power-off function again]

Turn the Function switch to the OFF, and then set it to any position.

7-2 Data hold function

This is a function to hold measured values on the display.

Press the Data hold button once to hold the current reading. In this

data hold state, the reading is held even if input varies. The "HOLD"

mark appears on the LCD. To exit the data hold state, press the

button again.

7-3 Backlight function

Press the Backlight button and turn on/ off the LCD backlight. The

backlight is automatically turned off in 30 sec.

7-4 MIN MAX function

Displayed values can be toggled in the following sequence by

pressing the  MIN MAX button.

Maximum value ( MAX appears) - Minimum value (MIN

appears) – Present measured value (MAX MIN blinks) -

Maximum value ( MAX appears) -…..

To disable this function, hold down the MIN MAX button at least 2

sec or rotate the Function switch.

8. Battery Replacement

# DANGER

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

is wet.

● Ensure that the Clamp sensor is disconnected from the object

under test, and that the instrument is powered off when opening

the Battery compartment cover for battery replacement.

● Never open the Battery compartment cover while making

measurement.

# CAUTION

● Do not mix new and old batteries or mix different types of batteries.

● Install batteries in correct polarity as marked inside.

Replace batteries with the new ones when the empty battery mark

  is displayed on the LCD. The LCD does not show anything,

even the empty battery mark, when the batteries are completely

exhausted.

[ How to replace batteries ]

(1) Power off the instrument.

(2) Loosen the screw at the backside

of the instrument and remove the

Battery compartment cover.

(3) Remove all the old batteries and

ins t a ll ne w o n es, two size AA A

batteries, in correct polarity. The

use of alkaline battery (LR03) is

recommended.

(4) Reattach the Battery compartment

cover and tighten the screw.
