The requirements are shown in the table in section Test gases – Caldos27
on page 29.
Test gases – Caldos27 on page 29 for instructions on test gases and possible limitations in
Dew point
The dew point of the test gases must be approximately equal to the dew point of the sample gas.
Note
The instructions for calibration must be observed, see Operating instruction.
