Abstract
In an FMCW-based fill-level measurement device, the fill-level value can be compensated with regard to component tolerances. A diagnosis unit of the fill-level measurement device compares the clock rate of the signal-generating PLL with the sampling rate of the analog/digital converter and determines a first compensation factor. With the aid of the first compensation factor, the determined fill-level value can be compensated with regard to these sampling or clock rates without any external high-precision reference source having to be used for this purpose.
