6.3.6 Calibration gas
WARNING
Gas connections may only be installed by qualified personnel!
If a pressure reducer is not installed, escaping calibration gas must be dis-
charged by the owner to a safe environment!
NOTE
•
Connection parts must be clean and free of residues. Contaminants may
reach inside the combustion calorimeter and may cause false measurements
and/or damage.
•
Calibration gas connection / compression fitting on side of combustion calo-
rimeter
•
The input pressure for the gas connections must not exceed the specifica-
tions of the technical data of the combustion calorimeter.
•
Calibration gas must be free of contaminants and condensate.
•
The calibration gas quality must be similar to the process gas quality.
•
Each connection point must be carefully checked for leak tightness. When
leaks are present, the system draws air and indicates false measured values.
•
Do not use sealant for sealing the gas connections. Sealant ingredients may
falsify the measurement result.
•
Only suitable lines may be used.
•
For device versions with 2 or 3 measuring ranges, up to 2 calibration gases
may be necessary.
•
Software-side configuration of the calibration gas.
