Using the demo software that comes with this project:
Leaving the jumpers for the analog inputs connected and adjusting the potentiometers, I can move the scroll bar all the way from 0 - 255. However, when I remove the jumpers and connect an external voltage (measured with an accurate multimeter). The voltage has to be set at +10V in order to reach the maximum value (255) on the scroll bar. The manual clearly states that +5V DC is the maximum that should be applied to the inputs.
What is going on here? I have not used either of the ‘gain’ resistors as 0-5V input is fine for what I need.
Im sure I must be doing somthing stupid…
