5 Test gases │ 27
Preset test gases
Test gases are preset in condition at delivery. These SEWERIN
test gases can be used to perform all the required device inspec-
tions and adjustments.
Information about the preset test gases can be found in sec-
tion 12.2.
Self-set test gases
Test gases other than preset test gases can be used provided
they meet the listed specifications. The test gases that are not
preset must be set up by the user by means of the GasCom
software. The test gas specifications are available on request.
5.3 Available test gases
Available test gases can be both preset and self-set test gases.
Test gases that are found in the list of available test gases (fig. 24,
right image) are theoretically available for device inspections or
adjustments.

To use the test gases in practice, they must be connected ( sec-
tion 5.5).
5.4 Planning for gas assignment
How effectively the test set can be used depends in particular
on whether the required test gases are available and connected.
SEWERIN recommends planning the gas assignment by reflect -
ing on the following questions:
1. Which devices need to be tested?
− Device version?
− Optional sensors?
− Self-set gas types?
2. Which device inspections must be carried out and how often?

A gas database is part of the GasCom software. In addition to the pre-
set test gases, the gas database can contain a wide range of self-set
test gases. Of all test gases in the database, up to a maximum of 7 can
be selected for a test set and assigned to it. All assigned test gases are
listed in the list of available test gases.
