Datasheet

Using the MC140i

MC140i Calibrator is equipped with a number of other functions which make it an attractive and useful instrument. Among them the possibility to set relative deviations from the actual value of the selected output signal, displaying of the output signal uncertainty, internal calibration procedure and more. The calibrator control and indication uses a large area luminescence display on which all necessary information is made available. The control is performed through simple menus. Moreover, frequently used functions have firmly assigned keys for direct control. As standard calibrator is equipped with RS-232 serial port making it possible to be controlled by personal computer. The MC140i calibrator can be included into Powertek WinQbase software calibration system.
