CA-C122 Clamp on Tester
current transformers for multimeter / suitable for oscilloscopes / 52 mm clamp diameter / measurable up to 1000 A / range selection switch

The Clamp on Tester from the C1XX series for multimeters measures the current up to 1000 A reliably. The Clamp on Tester can be connected via 4 mm (0.2 in) safety plugs to a multimeter. It is also possible to connect the Clamp on Tester via the 4 mm (0.2 in) sockets or the BNC connector to a data acquisition system. The C1XX Clamp on Tester features high accuracy, and has very good linear behaviour. This is due to the uniformly and symmetrically built windings in the Clamp on Tester. The diameter of the Clamp on Tester pliers are 52 mm (2 in).
