M3002A/M3014A Mainstream and Sidestream CO
2
Humidity Correction Factor
Either BTPS or ATPD can be selected as the humidity correction factor for the CO
2
readings. The
formula for the correction calculation is:
Where p = partial pressure, P
abs
= absolute pressure, and P
H2O
= 42 mmHg @35°C and 100% RH.
Mainstream CO
2
Humidity Correction Factor
Either BTPS or ATPD can be selected as the humidity correction factor for the Mainstream CO
2
readings. The formula for the correction calculation is:
Where p = partial pressure, P
abs
= absolute pressure, and P
H2O
= 47 mmHg @37C and 100% RH.
Warm-up Time 2minutes with CO

Performance Specifications
CO
2
Range –4 to 150 mmHg (-0.5 to 20.0 kPa)
Accuracy
after 20 minutes warmup and calibration:
For values between 0 and 40 mmHg: ±2.2 mmHg (±0.29 kPa)
For values between 40 and 76 mmHg: ±5.5% of reading
The specifications are valid for 45% O
