Calibrated Measuring Amplifier (C1250-Xx-Xc-Xs-Cxx); Description Of The Connectors / Interfaces - LinMot C1250 Series Installation Manual

7 Calibrated Measuring Amplifier (C1250 -xx-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%.
These drives have at least hardware version 1 revision H4 (V1RH4) and therefore come as well with an UL
listing.
The firmware must be at least version 6.9.
It is the user's responsibility to allow a reasonable period for recalibration. We recommend a calibration interval
of 12 months.
