This multi purpose process loop tool offers high accuracy in an ultra small rugged package. The mini source process calibrator has the ability to calibrate or troubleshoot any 4-20 mA loop device. A single push button allows the user to select one of the five current outputs (4, 8, 12, 16 or 20mA) which can drive up to 300 ohms or act as a two wire simulator with an external loop power supply of up to 30V DC. Typical applications include; chart recorders, panel meters, data acquisition systems and other process instruments.
