Power-Down of analyzer
Before the analyzer is disconnected from mains, it should be prepared for the
Power-Down, because
•
operational data should be stored
•
eventually changed user settings should be stored
•
the sensors should be purged with fresh air
Press the
OFF
key in any menu in order to prepare the analyzer for the Power-
Down. The analyzer will store operational data and user settings and will offer to
start a sensor purge cycle:
Start the purge cycle with the
F2 key (PIN code requested). The analyzer will purge
the sensors with fresh air and will indicate a count-down. Then the analyzer will be
ready for power-down.
Now it's not possible to continue directly the ordinary measurement process. Only
power-down by disconnecting mains or a software restart by pressing
F2 ='Reset
FW' is offered.
Note:
You also may enter this menu by pressing the
OFF
key and leave it by pressing the
ESC key (without starting the purge cycle) , when you just want to store operational
data and user settings.
Backup/restore all individual user-settings
It's a quite amount of work to configure the analyzer, especially when the analyzer
has several sample points, several IO-modules and when the analog outputs are
used. Therefore, we recommend to back up all your found settings on the SD card.
In order to back up the settings, do the following:
•
use the menu
E
XTRAS
.
•
insert an SD card (without write-protection)
•
press the menu key and select the function 'Export user settings'
The analyzer will write the backup file 'settings.usr' to the SD card.
In order to restore the settings, do the following:
•
use the menu
E
XTRAS
.
•
insert an SD card containing the backup file 'settings.usr'
•
press the menu key and select the function 'Import user settings'
The analyzer will replace the current settings by the settings from the backup file.
