Summary of change:
I'm building my own data acquisition system and I want to include Wbo2 logging. I am collecting info on how to control the LSU sensor. As an electronic engineer, I have found a little error in the Wbo2 section. In the Vs amplifier part, the code is Wbo2.nernst_target should be 0x8d. The first stage gain is, based on the schematic, Uout= 5 - ((5-Vs) x 4.6). For our application, we have 5-((5-4.45) x 4.6) = 2.47V => 0x7E and not 0x8D like in the code ?!?!?!?!?!? An other thing I can't understand: How do you calculate the real Ip in the sensor only, whithout knowing the sensor's resistance. A part of the current generated by the OPA is flowing also in the 10k resistor.
