The Fluke i400s Current Clamp is compatible with any instrument capable of ac millivolt measurements. and can accept a standard BNC connector, and has an input impedance of greater than or equal to 1 MΩ in parallel with a maximum of 47 pF. The Current Clamp can also be used with digital multimeters using a BNC-to-banana jack adapter. The Fluke i400s is specially designed to offer maximum utility in a compact shape and is the only current clamp available with a CAT IV 600 V / CAT III 1000 V safety rating. Fluke i400s current clamp extends the current ranges of digital multimeters, power quality analyzers, and portable oscilloscopes.
