Product Description:
space
space The SR661 is a range selectable probe that offers 3 switch selectable ranges of 20, 200 or 2000AAC. 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.

The Model SR661 is designed for use in industrial and utility environments. The unique ergonomic design allows it to easily clamp onto cables or small bus bars. It is built to the highest safety and performance standards including the CE Mark and is UL approved for Canada and United States. Excellent transformation and low phase shift, plus a broad frequency response, permit accurate measurements of current for power and power quality measurements. The high quality magnetic cores and uniform windings provide sensitivity for very low level current measurements, as well as measurements up to 1200AAC. The Model SR661 provides an accurate voltage output of 1mV/A to 100mV. This voltage output enables instruments without current ranges to measure, display log currents through an AC voltage range or measure very low AC. index mail web
