Fluke i1000s AC Current Probe Introduction The Fluke i1000s is a clamp-on ac current probe designed to expand oscilloscope applications in industrial and power environments. The Current Probe (shown in Figure 1) provides the following features: • Ideal for measuring distorted current waveforms and harmonics. • Allows accurate measurement of currents from 100 mA to 1000 A rms, 5 Hz to 100 kHz without breaking into the circuit.
i1000s Users Manual Tactile Barrier aef01f.eps Figure 1. i1000s AC Current Probe Box Contents The shipping container includes the probe, this users manual, 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. In this manual, a WWarning identifies conditions and actions that pose hazard(s) to the user.
AC Current Probe Safety Information WWarning • To avoid injury and ensure safe operation of the probe, follow all safety precautions detailed in this manual. • Never use the probe on circuits rated higher than 600 V in measurement category III (CAT III). Use extreme caution when clamping around uninsulated conductors or bus bars.

AC Current Probe Electrical Specifications Electrical Specifications Current Range: 100 mA to 1000 A ac rms (2000 A instantaneous peak). WWarning To avoid potential thermal burns from the jaws when measuring currents equal to or greater than 800 A ac rms in the ambient temperature range of 30 to 50° C (86 to 122° F), limit the measurement cycle to a measurement time of 5 minutes or less, followed by a cooling time of 15 minutes or more. Output Signal: mV output signal (2 V peak max).

AC Current Probe Operation Operation Use the following procedure to make a measurement: 1. Connect the i1000s Current Probe to the desired input channel on the oscilloscope. 2. On the Current Probe, select the least sensitive range (1 mV/A). See Figure 1 for selector switch location. 3. On your oscilloscope, select an appropriate range. Use a 1:1 probe setting. Note If using the Fluke ScopeMeter 123, use this procedure for step 3: 4. 1. Press 2.

AC Current Probe Measurement Considerations Measurement Considerations Observe the following guidelines for positioning the Current Probe jaws: • • • Carefully move the probe to center the conductor inside the jaws. Make sure the probe is perpendicular to the conductor. If possible, avoid measurements close to other current-carrying conductors. On the Current Probe, the 1 mV/A range offers the best accuracy and least phase shift.
