Checking OXYMAT 7 for leaks

Procedure
1. Close the reference gas inlet.
2. Connect the sample gas outlet to a pressure measuring instrument.
3. Apply a overpressure of 2000 hPa (relative pressure) to the measuring inlet.
4. Then block the measuring inlet.
5. Wait for 5 minutes until the sample gas that flowed in has reached the ambient temperature
and the pressure is stable.
Note the pressure.
6. Wait an additional 5 minutes and note the pressure again.
If the pressure change is less than 5 hPa, the sample gas path is adequately tight.
