AEMC’s MR527 is a hall effect current probe equipped with 2 ranges designed for oscilloscopes, waveform displaying instruments, and other frequency sensitive displaying instruments with BNC inputs. The MR527 offers a 6.5 ft (2m) lead terminated by a BNC connector and can measure up to 1000AAC and 1400ADC. The probe is powered by a 9V battery or by a standard 5V external power supply via a micro-USB connector (not supplied).
