These clamps serve for manually contacting windings, resistances or other electric connections in 4-wire configuration.

We recommend these clamps especially for testing low-ohmic resistances. Owing to the 4-wire configuration, the resistance can be determined precisely. Measuring errors through transition resistances at the contact point are eliminated.

The Kelvin clamps are very compact and have a handy design.
