AC Current Probe Model SR759
The SR759 probe is a range selectable probe that offers four switch selectable ranges: 1, 10, 100 or 1000A. This probe has a voltage output proportional to the current measured in the jaw of the probe. The SR759 has an integral 5 ft (1.5m) lead terminated by shrouded banana plugs compatible with DMMs and other instruments. The high accuracy, high sensitivity and low phase shift makes this probe an excellent choice for use in a wide range of power quality applications, including very low or leakage current measurements.
