1. A method of adjusting a quantization accuracy of a fill level radar and/or an ultrasonic measuring device for detecting a fill level of a container, the method comprising the steps of:
acquiring amplitude values of an echo curve of the fill level radar and/or the ultrasonic measuring device by means of an analog-to-digital converter (ADC);
determining a first amplitude value of a first echo having a highest amplitude or a highest local amplitude maximum of the echo curve;
determining a second amplitude value of a second echo having a lowest local amplitude maximum of the echo curve;
setting an adjusted quantization accuracy as a function of a quotient of the first amplitude value and the second amplitude value; and
determining the fill level of the container with the adjusted quantization accuracy.
