| The LSU4 sensor male connector housing has a resistor (min-max is 35-300 Ohm, but usually 90-190 Ohm): measure resistance between pin2 and pin6. |
| The LSU4.2 sensor male connector housing has a resistor (min-max is 35-300 Ohm, but usually 90-190 Ohm): measure resistance between rcal=pin2 and pump+ = pin6. (rcal=pin5 and pump+ = pin1 for LSU4.9 and possibly >300 Ohm resistance). |
| This is not a replacement for free-air calibration, just gives a starting value (so the best calibration value can be found faster). |
| This is not a replacement for free-air calibration, just gives a starting (ballpark) value, but starting from some low calibration=50..130 value is just as good (increase gradually to show 20.9% O2). |
| Some statistics from actualy calibration - show that higher calibration value is needed than the above table suggests |
