2. Leak test by connecting together the sample 'IN' and sample 'OUT'
gas connections and connect a water manometer to them.
3. Pressurise the system to approx. 500mm water gauge and leave to
stabilise. The leak rate should be less than 2mm/min. after the level
has initially stabilised.
4. If a leak exists, check connections using a soap solution. This testing
should also include the oxygen cell and its window.
5. Rectify leaks and re-check.
