INTRODUCTIONThe Fluke 80i-500s is a clamp-on current probe that is designedto reproduce current waveforms found in modern commercialand industrial power distribution systems. The probe’sperformance is optimized for accurate reproduction of currents atline frequency and up to the 50th harmonic. The 80i-500s is alsocompatible with any instrument capable of millivoltmeasurements. •Ideal for measuring distorted current waveforms andassociated harmonics. •Allows measurement of currents from 1 to 500A ac rms, 5Hz to 10 kHz without breaking into the circuit. •Provides an output of 1 mV ac per 1 amp ac. •A passive filter eliminates noise and ring on rapidly risingwaveforms, ensuring accurate reproduction on oscilloscopedisplays. •Rated for 600V circuits of Overvoltage Category III per IEC1010-1. (See “Safety Specifications” for an explanation ofOvervoltage Categories.)
