AC Current Probe Model SR661
The SR661 is a range selectable probe that offers 3 switch selectable ranges of 10, 100 or 1000AAC. This probe has a voltage output proportional at the current measured in the jaw of the probe. The SR661 has an integral 6.5 ft (1.98m) lead terminated by BNC connector. The high accuracy and wide frequency response makes this probe an excellent choice for use with oscilloscopes.
