SR752 is a general purpose 1000AAC current probe designed for use with DMMs, loggers and other instruments that have voltage inputs. It has a voltage output proportional at the rate of 1mV per amp to the current measured in the jaw of the probe. The SR752 has an integral 5 ft (1.5m) lead terminated by shrouded banana plugs.
