SR704 is a general purpose 1000AAC current probe designed for use with DMMs, loggers and other instruments that have a current input. It has a 1000:1 ratio and output of 1mA per amp measured in the jaw. The SR704 has an integral 5 ft (1.5m) lead terminated by shrouded banana plugs. The rounded jaw design on this probe makes it well-suited for power applications where high accuracy and low phase shift and wide frequency response are important.
