8 Calibrated Measuring Amplifier (C1250-MI-XC-xS-Cxx)
The drives with the ending -Cxx are specially designed for measuring applications. They come with a factory calibration
certificate for the analog inputs on X4. The analog inputs on X4 provide a measuring error of less than 1%.
It is the user's responsibility to allow a reasonable period for recalibration. We recommend a calibration interval of 12
months.
