When we calibrate the wbo2 sensor we need to change values in wbo2 config.

[manual]

1: calibrate (wbo2_pump_pw_zero) measure the voltage between pins 5 and 6 of the wideband connector The ideal voltage is so cloce to zero (0) as passebele. To adjust the voltage, change the value of wbo2_pump_pw_zero in config.txt or Megatune. A good starting point value should be between 0x64 to 0x66 decimal 100 – 102.

2: Place a 100 Ohm resistor between pump+ (pin 6) and nernst (pin 1)

3: Place a 100 Ohm resistor between pump- (pin 5) and nernst (pin 1)

4: Open the terminal program

5: Turn on the WBO2 heater by typing “Man” then “mde02” then “mlp07” to get to the wbo2 page at the display.DUE NOT CONNECT THE WBO2 SENSOR YET

6: Measure the voltage between ground and pump- (pin 5). It should read 3.96V.

Measure the voltage between ground and nernst (pin 1). It should read 4.41V.

Measure the voltage between nernst (pin1) and pump- (pin 5). It should read +450mV.

8: The ajustment can be don from mega tune

IF SOME ONE CAN HELP WITH THE NEXT STEP

8: To adjust the voltage between ground and pump- (pin 5).= Tag ???

To adjust the voltage voltage between ground and nernst (pin 1).= Tag ??? adjust nernst_dc_target if that due not worke then ??

To adjust the voltage between nernst (pin1) and pump- (pin 5).0 Tag ???
