Self-Test
The first menu to be displayed after Power-On is the self-test menu. The analyzer
won't leave this menu before all sub-systems will be connected and the gas cooler
(option) has reached the target operation temperature.
During the self-test phase
•
the gas pump is switched off
•
all analog outputs will deliver 2mA
•
all alarm outputs will have alarm status (open contacts)
Usually the self-test will be left automatically as soon as all conditions for
measurement are satisfied. Then the first zeroing will be started.
If one of the internal RS485 bus participants are issuing alarm (faulty) status, the
user can still leave the self-test manually by pressing F2='forward' (PIN code
requested), even if not all sub-systems or the gas cooler are ready.
NOTE: this is for service purpose only!
Main menu measurement
This menu is the root of all menus and will be shown automatically as soon as the
self-test is finished. The title bar you can see on the left the current measurement
cycle status and how long it lasts and the actual sampling point number. In the
middle section of the actual measurement values are displayed.
Representation during the status "measurement"
The title bar you can see on the left "measurement" and the remaining
measurement duration, and the right light blue highlighted sampling point
number SPx (x = 1 to 10) that is being measured. In the middle section of the menu,
the current (live) values are displayed.
Representation outside the status of "measurement"
The title bar you can see on the left "air purging" or "gas sampling SPx" and the
remaining duration of the current status. On the top right you can see the yellow
highlighted sampling point number SPx previously measured or that you have
selected for display and their measuring values are held until it is measured again.
In the middle section of the menu held measured values of these measurement
sites are displayed.
