A value of 224 .. 240 allows proper heating, eg. 224 with 13V supply means max sqrt( 13 * 13 * 224 / 256)=12.16V RMS voltage wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_ri_target=96 wbo2_nernstdc_target=89 wbo2_pump_pw_zero=64 wbo2_calibration=B9 wbo2_heater_pid_kp=45 wbo2_heater_pid_ki=11 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=81 wbo2_pump_pid_kp=15 wbo2_pump_pid_ki=4E wbo2_pump_pid_kd=00 wbo2_pump_pid_ilimit=FF wbo2_ri_confidence_scale=80 ---- '''Previous problems to learn from: 12SEP2007''' My O2% value wouldn't read over 16.0%, not even with wbo2_calibation =0xFF. The problem was that for some reason wbo2_abs_limit was set to 0x00, preventing the sensor from heating properly. Once increased it was possible again to correctly calibrate the sensor in free air with wbo2_calibration parameter.
