80i-500s
AC CURRENT PROBE FOR OSCILLOSCOPES
Instruction Sheet
INTRODUCTION
The Fluke 80i-500s is a clamp-on current probe that is designed to reproduce current waveforms found in modern commercial and industrial power distribution systems. The probe’s performance is optimized for accurate reproduction of currents at line frequency and up to the 50th harmonic. The 80i-500s is also compatible with any instrument capable of millivolt measurements.
∙Ideal for measuring distorted current waveforms and associated harmonics.
∙Allows measurement of currents from 1 to 500A ac rms, 5 Hz 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 rising waveforms, ensuring accurate reproduction on oscilloscope displays.
∙Rated for 600V circuits of Overvoltage Category III per IEC 1010-1. (See “Safety Specifications” for an explanation of Overvoltage Categories.)
WWARNING
Read “Safety Information” Before using the probe.

BOX CONTENTS
The shipping container includes the 80i-500s Current Probe, this Instruction Sheet, a Quick Reference Card, and a product registration card.
SAFETY INFORMATION
Read the following safety information carefully before attempting to operate or service the current probe.
∙W Never use the probe on circuits rated higher than 600V in Overvoltage Category III (CAT III) or 300V in Overvoltage Category IV (CAT IV) of IEC-1010-1. (See “Safety Specifications”.) Use extreme caution when clamping around uninsulated conductors or bus bars.
∙Keep your fingers behind the finger guard.
∙Check magnetic mating surface of the probe jaws; these should be free of dust, dirt, rust, and other foreign matter.
∙Do not use a probe that is cracked, damaged, or has a defective cable. Such probes should be made inoperative by taping the clamp shut to prevent operation.
In this instruction sheet, a WARNING identifies conditions and actions that pose hazards to the user. A Caution identifies conditions and actions that may damage the current probe. International electrical symbols used are explained in Figure 2.
