AEMC AC/DC Current Probe Model MR417 The MR417 is a hall effect current probe with 2 ranges designed for oscilloscopes, waveform displaying instruments, and other frequency sensitive displaying instruments with BNC inputs. The probe has a 6.5 ft (2m) lead terminated by a BNC connector and can measure up to 400AAC and 600ADC. The probe is powered by a 9V battery or by a standard 5V external power supply via a micro-USB connector (not supplied).
