Hi,
the docs say that the middle pin is inactive.
Nevertheless I tried it, left pin 5V, middle pin analogpin, right pin GND with resistor.
With 1 MOHM 1 get no load: 1,9 V max load: 4,3V
With 100 KOHM no load: 1,9V max load: 3,4 V
Without resistor no load 1,9V max load: 1,9V
Are these better results?
The value is changing about 5 % all the time without any change in weight, but I think this is normal for such a sensitive resistor?
Do you think everything is ok now?
With which resistance I may get the best results?
Many many thanks for your help.
Ralf
