The AEMC MR417 and MR527 models are Hall Effect current probes designed for oscilloscopes, waveform displaying instruments, and other frequency sensitive displaying instruments with BNC inputs. Both MR417 and MR527 models have two ranges and a 6.5 ft (2m) lead terminated by a BNC connector. The MR417 can measure up to 400AAC and 600ADC and the MR527 can measure up to 1000AAC and 1400ADC. Both probes are powered by a 9V battery or by a standard 5V external power supply via a micro-USB connector (not supplied).
