6. Press the Menu key while being in the gas quality main display and activate
the
TG path 1 start
or
TG path 3 start
command in the invoked menu.
7. Now, the sensor system will be purged with test gas for about 2 minutes.
Afterwards, the measurement begins. The measurement results are shown
in the main display.
8. To finish the test gas injection, press the Menu key and activate the
TG
path 1 end
or the
TG path 3 end
command.
9. Now please turn off the test gas cylinder and remove the tube on both
sides.
(Caution: Unpressurise the line first!).
A running test gas injection will be aborted automatically after 1 hour (which can
be parameterised), and process gas will be injected instead.
When gas path 1 was used, make sure that after the test gas injection the
process gas is reconnected and opened to this path. Otherwise the test gas is
handeled as process gas and the measurement results are mapped incorrectly.
