Chauvin Arnoux P01295494 Set of 2 Kelvin clamps Hippo 200 A – 6 m content_copy

This spare part from Chauvin Arnoux is specifically designed for the Micro-Ohmmeter C.A 6292 and is used for precise measurement of very low resistances. It consists of a set of two Kelvin clamps of the Hippo type, each with a maximum current rating of 200 A. The clamps are available in red and black and enable four-wire measurement, minimizing contact resistances to enhance measurement accuracy. The connection cables have a length of 6 m, providing sufficient flexibility for measurements at a distance from the measuring device.

Four-wire measurement is the method in which the measurement current is supplied via two separate lines (current clamps), while the voltage is measured on two additional lines (measurement clamps). This eliminates the influence of contact resistances at the connection points, which is particularly crucial when measuring very low resistances. The Kelvin clamps are designed for this purpose, ensuring a secure and stable connection to the measurement object.

Technology explained clearly

The Kelvin clamps Hippo are mechanically robust and allow for secure attachment to measurement points, such as cable ends, screw terminals, or other metallic surfaces. The current rating of 200 A means that the clamps can operate safely even under high current loads without overheating or loosening. The cable length of 6 m provides sufficient flexibility to position the measuring device away from the measurement object, which is especially beneficial for large machines or confined installations.

Compatibility and accessories

This accessory is exclusively intended for the Micro-Ohmmeter C.A 6292. It is not a universal accessory but specifically adapted to the interfaces and requirements of this device. Use with other measuring instruments is not intended and may lead to inaccurate results or damage.

Applications

This spare part is used in applications requiring high measurement accuracy for very low resistances. Examples include testing electrical connections, cable joints, switchgear, transformer connections, or during maintenance of industrial machinery. Four-wire measurement is essential here to avoid measurement errors caused by contact resistances.

Installation and mounting

The Kelvin clamps are attached directly to the measurement points. The current clamps (red/black) are connected to the current terminals of the measuring device, while the measurement clamps (for voltage measurement) are connected to the corresponding measurement terminals of the device. The cable length of 6 m allows for flexible positioning of the device.

Operational advantages

Using these Kelvin clamps increases the reliability and accuracy of measurements, especially for resistances in the milliohm range. The robust design of the clamps ensures a secure connection, and the cable length of 6 m provides flexibility in positioning the measuring device. The color coding (red/black) simplifies assignment of the clamps to the corresponding terminals on the device.
