The PRESYS LC-505 Process Loop Calibrator enables measurement and generation of signals used in DC current (4-20mA) and voltage (1-5V, 0-10V) loops.
Distinguished from regular loop calibrators due to its high-accuracy, possibility of simultaneous measurement and generation of isolated signals, real time connection with computer, working as a data acquisition point and full computer-aid for instrument calibration and adjustment tasks.
Its accuracy refers to changes in room temperature and maintenance of specifications for a long time of use. Designed for field use, it contains useful items as carrying case holders with fastener rings or belts for a hands-free operation, a high contrast LCD for a better viewing in poor lighting conditions, besides presenting measured and generated signals with large digits so that they can be seen far away.
It includes rechargeable battery, and a high-size memory intended to store values obtained for a later upload to a computer, when applicable. Moreover, various other constructive features aggregate quality and efficiency to LC-505, allowing also its field and workbench use
