4. PIN ASSIGNMENT FOR OUTPUT TERMINAL

The pin assignment for the output terminal of this clamp sensor is as

follows.

* Pin assignment at the connecting terminal of measuring instrument

is symmetrical to above figure.

Output signal passes between 3 and 5 of Output terminal.

This clamp sensor is supplied power via an Output cable. Power

supply of +3.0 to +5.5V is required between 1 and 3 of Output

terminal and -3.0 to -5.5V is required between 2 and 3 of Output

terminal.

#

WARNING

Never attempt to make any measurement if any abnormal

conditions, such as a broken cover or exposed metal parts are

present on the clamp sensor.

Do not disassemble, install substitute parts or make any

modification to the clamp sensor. Return the clamp sensor to

your local KYORITSU distributor for repair or re-calibration in

case of suspected faulty operation.

Do not use the clamp sensor if the clamp sensor or your hands

are wet. Otherwise, electrical shock accident may occur.

Use insulated protective gears for your safety when using this

clamp sensor.

#

CAUTION

Do not step on or pinch the cord; it may damage the jacket of cord.

Do not expose the clamp sensor to direct sunlight, high temperatures,

humidity or dew. Otherwise, it may cause deformation or insulation

degradation and cannot meet the original specification.

Not to give shocks, such as vibration or drop, which may

damage the clamp sensor, during transit or use.

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

clamp sensor. Do not use abrasives or solvents.

This clamp sensor is not designed to be dust or waterproof. Do

not use it dusty places or where the clamp sensor is likely to be

wet. It may cause troubles on the clamp sensor.

Never pinch foreign matters or give vibrations at the jointed

parts of this clamp sensor. Otherwise, matching area of Jaws

may be damaged and cause influences on the measurements.

Do not bend or pull the root of the cable in order to prevent

breaks in the cable.

Never apply the current exceeding the measuring range for a

long time. It may damage the clamp sensor.

Never connect/remove the connectors while connected devices

are on or clamping onto the conductor under test. Otherwise, the

connected devices or clamp sensors may be damaged.

Accurate measurement may not be obtained in the vicinity of

strong magnetic fields such as transformers, high-current

circuits or wireless machines.

#

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

With attention to the measurement category to which the object

under test belongs, and do not make measurements on a circuit

in which the electrical potential exceeds the following values:

300V for CAT. IV and 600V for CAT. III or lower categories.

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-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 over-current

protection device (distribution panel).

6. OPERATING INSTRUCTIONS

#

DANGER

With attention to the measurement category to which the object

under test belongs, and do not make measurements on a circuit

in which the electrical potential exceeds the following values:

300V for CAT. IV and 600V for CAT. III or lower categories.

#

CAUTION

The measurable conductor size is max. 110mm in diameter.

Accurate results cannot be obtained if the clamp sensor is not

closed firmly.

When disconnecting the output terminal from the measuring

instrument, do so by removing the plug first and not by pulling

the cord.

6-1 Measuring method

(1) Connect the output terminal to the input terminal on the

measuring instrument.

(2) Power on the measuring instrument.

(3) Press the Joint according to the following illustrations and

unlock it.

(4) Clamp onto one conductor under the test. Locate the conductor

to the position as shown in the below figure. When connecting

the Clamp sensor with our Power meter (MODEL6315 etc.),

check the direction of the Guide arrow mark indicating the

current flowing direction marked on the Joint of the Clamp

sensor to make the phase of the current under test and output

voltage synchronized.

(5) Confirm that the Joint on the Clamp sensor is firmly locked.

● 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.

6-2 Connecting with Power meter (KEW6315/KEW6310/KEW6305/

MODEL6300)

When this clamp sensor is detected by the auto-detection function

of our KEW6310/ 6315 Power meter after the connection, the type

of the clamp sensor will be displayed as follows. On KEW6310, the

displayed model name will not be “KEW8130”, however, this is

not a malfunction. Enter the model name according to the following

table if setting the type of the clamp sensor directly.

Power meter

Model name displayed through

the auto-detection function

KEW6310

MODEL8124

KEW6315

MODEL8124/8130

● MODEL6300/ KEW6305 does not detect the connected clamp

sensors automatically. Enter the model name directly:

MODEL8124 (1000A).

● For the detailed setting of the clamp sensor, please refer to the

instruction manual for each Power meter.

6-3 Connecting with Logger (KEW5010/5020)

When using this clamp sensor together with our KEW5010 / 5020

Logger;

(1) Connect the clamp sensor to

CH1 of KEW5010/ 5020 while

KEW5010 / 5020 is in powered

off status.

(2) Then power on KEW5010 /

5020. Time will be displayed,

and then

and “1000A”

will be displayed. (KEW5010/

5020 checks the connected

clamp sensors when it is

powered on, and detects and

displays the clamp sensor type and a proper range

automatically.)

(3) Now the instrument is ready for

measurements. When “

(no

connection) is displayed on the

LCD; it means no clamp sensor is

connected to the selected channel

or the connection is loose.

In this case, check the connection and reconnect the clamp

sensor,and power off KEW5010 / 5020. Then power it on again.

* Only KEW5010 / 5020 which have the following or later serial

number may be used with this clamp sensor.

KEW5010: No.8031560 or later

KEW5020: No.8029792 or later
