Proceed as follows:
Step Procedure
1 Connect a test gas to the test gas input.
2 Connect a discharge line to the test gas output.
The validation is used to check the functional capability of the analyzer.
For the test gas, a gas mixture must be used that contains the measured
component in a concentration suited to generating a significant change in the
display of measured value (typically approx. 80 % of the upper range value, for
approximate values refer to the following tables).
