GasLab Q2
7.3.4 Operation mode: Verification (special operation)
This operating mode can be used for device check. It can be executed manually (similar to chapter
7.3.3) or automatically (see chapter 8). For this purpose, a test gas of known composition is
analyzed and the results are compared with the data from the manufacturer's analysis certificate
of this gas.
The test gas must be connected to the process gas inlet for this operation. If
the measurement should start the verification automatically, an automated
3-way valve must be installed in the gas flow.
The analysis data of the gas must be exactly defined, a deviation causes
invalid values.
The comparison is possible directly on the displays. Navigate with the overlay keys to the
Verification
display, select "
Deltas
" in the top line. This display shows the differences between
the results of the measurement and the stored data of the manufacturer analysis certificate. You
will see this data when you select "
References
" on the
Verification
display. You can also see
the values HsV and Rho calculated from the gas composition and the indicated standard. It is
also possible to enter and / or adapt values to the manufacturer's analysis certificate, if you are
logged in and authorized.

The results obtained can also be
stored in an archive, e.g. archive “Test Gas”. This archive must
have been created beforehand in enSuite (
See chapter 8). If the device is working in the normal
analysis mode, login (as described in chapter 7.3.6) to to perform a manual verification.
The following can only be carried out if the security switch (SSW) conditions
(shown in enSuite, see chapter 8) are met.
If you are loged out during execution, you can no longer access the (remote)
operation panel for this operation. The last confirmed function is executed
further. Log in again to continue the steps.
