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.

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.

Meaning of symbols on the clamp sensor:

| User must refer to the explanations in the instruction manual for safety reasons.
---|---
| Clamp sensor with double or reinforced insulation

| Do not apply around or remove from un-insulated hazardous live conductors, which may render electric shock, electric burn, or arc flash.
| AC
| 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 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).

FEATURES

• This is a Clamp Sensor capable of measuring AC current up to 1000A.
• Flexible and light weight because of an air core coil used at the Clamp Sensor part

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 measuring instrument. terminal to the input terminal on the

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.

• MODEL6300/ KEW6305 does not detect the connected clamp sensors automatically. Enter the model name direct ly: 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 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
