Designed to extend the AC current range of Fluke’s digital multimeters, power quality analysers, and portable oscilloscopes. This compact clamp meter provides a measurement range of up to 400 A AC and can be used to test conductors with diameters up to 32mm. It is CAT IV 600V/ CAT III 1000V safety rated and features a soft non-slip over-mould handle. Available individually or in a set of three, the Fluke i400S 400A Current Clamp provides an ergonomic, easy method of taking accurate AC current readings without breaking the circuit.
