Air Sample Time (Air)
The air sample time can be set separately for bump testing and
calibration. It is the length of time that a SM-2009U will draw air through
the AIR fitting on the back of the station. Air is drawn during a bump test
before an air adjust operation and to purge calibration gas from the
system after calibration gas has been drawn through the CAL. GAS fitting
on the back of the station.
Calibration Gas Sample Time (GAS)
The calibration gas sample time can be set separately for bump testing
and calibration. It is the length of time that a SM-2009U will draw
