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

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