Abstract:
1. A measuring device electronics for a measuring device, said measuring device electronics comprising: a processor; a first clock signal generator for producing a working clock signal clocking the processor with a nominally constant clocking frequency and for producing a first reference clock signal dependent on the working clock signal, said first reference clock signal exhibiting a nominally constant clocking frequency which is smaller than the clocking frequency of the working clock signal by a predetermined factor; and a second clock signal generator for producing a second reference clock signal independent of the working clock signal, said second reference clock signal exhibiting a nominally constant clocking frequency which is smaller than the clocking frequency of the working clock signal by a predetermined factor, wherein said processor is adapted to detect, based on said first reference signal as well as based on said second reference clock signal, whether at least one of said first and second clock signal generators is delivering a reference clock signal with an instantaneous clocking frequency, which deviates by a predetermined degree from the nominal clocking frequency respectively predetermined therefor.
