Precision You Can Trust
NABL-Accredited Calibration | Available on Request

The Messkabel (measuring cables) are essential accessories for DPG10 and DPG20 series power choke testers. They provide precise 4-wire connections for devices ranging from tiny SMD components to large power chokes over 1,000 kg. Specially designed for safe high-current operation, these cables ensure accurate measurement by separating measuring current and sensor leads..

  • Specification

The measuring cables for the DPG10 and DPG20 series are tailored for precise, high-current inductance measurement. The standard 4-wire configuration separates the measuring current from the sensor connection, ensuring highly accurate readings even under pulsed high-current conditions.

Kelvin measuring leads simplify the connection process with only two terminals per lead, each with insulated jaws to separate current and sensor paths. Extra-long cables allow testing of very large components or objects with widely spaced connections, though measurement uncertainty can increase at very low inductances.

All standard cables can connect to compatible sockets (4 mm or 6 mm), with DPG20 models using the larger 10 mm connectors for extreme currents. Custom cables are available to meet special size or current requirements.

  • 4-wire connection for precise inductance measurement

  • Available in various lengths and cross-sections for small to very large inductors

  • Separate measuring current and sensor leads reduce measurement errors

  • Compatible with both 4 mm and 6 mm device sockets

  • Extra-long cable sets available for large or widely spaced components

  • Custom cable options can be manufactured upon request
