The Fluke I1010 is a 1000 Amps AC/DC Current Clamp for DMMs. This Fluke current clamp is ideal tool to extend the current ranges of digital Multimeters. Battery-powered Hall-effect probe measures 1 Amps to 1000 Amps. 1mV/Amps output guarantees easy reading on your meter. Take accurate current readings without breaking the circuit The i1010 AC/DC current clamp allows Multimeters to measure up to 600A AC or 1000A DC. Current range: 1A to 600A AC or 1A to 1000A DC. Basic accuracy DC or 45Hz to 400Hz: +/- (2 percent of reading +0.5A). Output signal: 1mV/A AC/DC. Frequency range: 45Hz to 2kHz. Bandwidth: 10kHz Working voltage: 600V AC RMS. Maximum conductor size: one 30 cm (1.18") or two 25mm (0.98") diameter. Safety rating: EN61010, CAT III 600V.
