Abstract
A measuring device electronics comprises a processor and two clock signal generators. One clock signal generator serves for producing a working clock signal, and also for producing a reference clock signal which is dependant on the working clock signal. The other clock signal generator, serves for producing a second reference clock signal, which is independent of the working clock signal. Based on the two independent reference clock signals, a frequency difference, can, to the extent that such is present, be ascertained during operation of the measuring device electronics or of the measuring device formed therewith. The frequency difference, represents a difference between the instantaneous clocking frequency of the first reference clock signal and the instantaneous clocking frequency of the second reference clock signal, and, in this respect, represents a measure for a deviation of an instantaneous clocking frequency, from the nominally predetermined clocking frequency, of the working clock signal.
