10.4.1 Connect/replace calibration-, verification- gas
cylinders
For proper operation of the instrument, regular automatic calibration/adjustment
with a calibration gas is necessary. Refer to section
measuring device (p. 65)
As soon as the outlet pressure of a gas cylinder can no longer be kept stable, it
must be replaced. Depending on the regulator, this may occur at a pressure around
1.0 MPa (g). If the pressure is below 2 MPa, you should have a replacement cylinder
ready. therefore monitor the cylinder pressure with e.g. a pressure gauge or contact
manometer.
The recognized rules of technology for handling gases must be observed for all
work as described. Surfaces that come into contact with gas must be free of grease,
oil, solvents and other contaminants. Take steps to prevent dirt and/or moisture
from reaching the unit during replacement.
