AC oscilloscope current probes

27 March 2002 Test & Measurement

LEM's PR1230 and the PR1235 current probes are for use with oscilloscopes, analysers and recorders for accurate nonintrusive measurement of AC current. The PR1230 has a measuring range of from 100 mA to 1200 A, whereas the PR1235 is capable of measuring currents as small as 10 mA. The frequency range is 30 Hz to 300 kHz (-3 dB), and output signal for both probes is 1 mV/A. The jaw opening is 54 mm and the probe is equipped with an integral cable and a BNC connector. No battery or external power is required.
