The growing amount of various electrical sensors in marine electronics makes instruments like JOFRA ASC300 more and more useful. Quick and easy measurement and simulation make it ideal for maintenance and calibration. The JOFRA ASC300 combines a full numerical keypad with a series of function keys and a graphical user interface, which makes it easy to perform various tasks in a short time. The two channels provide the user with an isolated read-back circuit. The JOFRA ASC300 has full fuseless protection to 240 VAC, which is an important feature as most failures in signal calibrators derive from over-voltage conditions. As the instrument is compatible with JOFRA APM pressure modules, it offers a true multi-function operability. Major Features: Accuracy to В±0.2oC / 0.36oF, Simultaneous input and output, Input and output: TCs (13 types), RTDs (14 types), 0-20 VDC, 0-24 mA, 5-4000О©, 0-10 kHz, and pulse trains, Isolated read-back circuit with 24 VDC loop power, APM pressure module input for pressure applications
