At the end of the warm-up phase the gas analyzer is ready to carry out measure-
ments.
The gas analyzer is calibrated in the factory. Transport stresses as well as
pressure and temperature conditions at the installation location may however
influence the calibration. Thus it is recommended to verify the gas analyzer
calibration at the installation location.
Chapter 8 describes the gas analyzer calibration procedures.
The sample gas supply should be turned on only after calibration.

Gas Module
In the Caldos25 and Uras26 analyzer module versions with flowing reference
gas, the reference gas flow rates must be set to the same value as the sample gas
flow rate.
For special applications of the Caldos25 the reference gas flow rate must be set
to lower values down to 1 l/h.
The purge gas flow rate should be set as follows in gas analyzers with the housing
purge capability:
Purge gas flow rate at device inlet max. 20 l/h (constant),
Purge gas positive pressure p
• Because of leakage losses the purge gas flow rate at the device output is
approx. 5 to 10 l/h for a purge gas flow rate at the device inlet of 20 l/h.
• Notes for selection and use of flow meters:
• Measuring range 7 to 70 l/h
• Pressure drop < 4 hPa
• Needle valve open
• Recommendation: Flow meter 7 to 70 l/h, Catalog No. 23151-5-8018474
