slayerizer, The zener does not pull the pin to 0 volts but, starts to conduct at the breakover voltage it is designed for. It will then maintain that voltage as long as the power of the component is not exceeded. In other word it is acting as a limiter....

Yes but not like a switch! It is like a normal diode in characteristics slightly steeper. But has a knee. That means if voltage is increasing above about 4,3Volts the zener might start to conduct and spoil the readings of the ADC.Originally Posted by Dave
I may have not stated correctly in engineering terms. If anyone with native english understood, please help here.
