Measuring Range Extension of the
Analog Inputs
You can extend the measuring range of each analog input to a
higher maximum voltage than 5 Volts by using a voltage divider. On
delivery of the motherboard the resistor positions R30 and R43 on
the bottom side of the PCB are not equipped. By inserting a resistor
