Siemens dew point unit

The unit atmosphere must be allowed to stabilize in order to obtain an accurate sample and dew point reading. After a unit has been pressurized with dry air or nitrogen, the unit must sit for 6-12 hours to allow temperature and moisture stabilization. The time and date of final pressurization is to be recorded.
