This page is intended to document the actual method to WBo2 calibration for Vems 3.x process in one location in an easy to understand format for use with a windows box and MegaTune\n
5V / 256 = 0.019 V / bit +/-20mV is minimum 170 changed to 20.0 (3.824) 175 changed to 20.3 (3.843) 180 changed to 20.5 (3.863) 190 changed to 21.2 (3.902) 185 changed to 20.9 (3.882) 186 changed to 21.0 (3.882)
I guess we should recommend a starting value (RCal=115 Ohm or so), and get the user read the O2% in free air. We make a table which the user can look up in 1 step => voila: WBO2 is calibrated.
