The Fluke 87-5/EUR blocks unwanted high frequencies generated by motor drive electronics at the push of a button, allowing for precise and stable measurement of the most important readings for motor drives. Fluke current clamps are the ideal tools to enhance the functionality of Fluke measuring devices. The i400 is an AC clamp with a single measurement range of 400 A and a current output via shielded 4 mm safety plugs. The clamp is compatible with most Fluke multimeters and all other current measurement instruments suitable for shielded 4 mm safety plugs, operating in the AC range from mA. The turn ratio is 1,000:1.
