Pressure: 1050 hPa.
Calibration pressure: 1000hPa.
Sensor age: new.
**Measurement Accuracy: **
5.23%CO2 ±0.15%CO2 = 5.08%CO2<x<5.38%CO2.
**Temperature Dependence: **
5.23%CO2 ±10% of reading = 4.707%CO2<x<5.753%CO2.
**Pressure Dependence: **
**Step 1: 5.23%CO2 ±0.15% of reading/hPa = 0.007845%CO2/hPa. **
Step 2: Pressure difference: 1050hPa-1000hPa=50hPa.
Step 3: 0.007845*50=0.39225%CO2.
Total: 4.83775%CO2<x<5.62225%CO2
