This is an AEMC SL261 AC/DC Current Probe.  This unit is in great condition and guaranteed fully operational.  I have several of these, all identical.  One per bid

AC/DC Current Probe (BNC - 100mV/A - 10A peak & 10mV/A - 100A peak)

The Model SL261 is designed for AC/DC current measurement capabilities using Hall effect technology. It measures from a few mA to over 100A. The “screwdriver” shape, with its narrow elongated prod, was chosen to permit probing in crowded cable bundles or measuring in tight areas such as on circuit boards, motor controllers, and automotive circuitry.

The electronics and batteries are self-contained in the handles. It is an excellent companion to DMMs, recorders and loggers, oscilloscopes, and waveform displaying instruments. Low phase shift also ensures reliable power and power quality measurements. The Model SL261 is designed for current measuring and displaying on oscilloscopes. AC + DC output signals proportional to the total current are provided for True RMS measurement.

Applications

  • Oscilloscope applications in industrial or power environments
  • Analysis and measurement of distorted current waveforms and harmonics
