I am using input 1 as 2-wire 0-10V sensor. For testing purpose I connect a batteryblock of 2,5 V. In “advanced configuration” I set the port to “analogue input without internal pull up”. I presume internal means there is a pull-up resistor in the Smart Implant?. There is also the option “analogue input with internal pull-up”. When should I use that option?
