Calibration Calculations
Calibrated oxygen reading:
O
2RC
= C
0
+ C
1
× O
2RU
Where:
C
1
= (O
2
100%Sat)/(O
2RUS
× O
2RUZ
)
C
0
= –C
1
× O
2RUZ
Where:
O
2
100%Sat is the theoretical 100% saturation point
O
2RUS
is the uncalibrated reading at 100% saturation
O
2RUZ
is the uncalibrated reading at 0% saturation
