• Measurement range of 100mA to 2000AAC
• Large jaw opening accommodates conductors up to two 500MCM conductors
• Ergonomic design and easy operation
• Conforms to EN 61010, 600V Cat. III safety standard
• Low phase shift for power measurements

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 to the current measured in the jaw of the probe. The SR661 has an integral 6.5 ft (1.98m) lead terminated by a BNC connector. The high accuracy and wide frequency response make 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.

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.
