3.3 Display
The display is an illuminated LCD consisting of 8 lines with 32 characters each.
After approximately 30 minutes without a keystroke, the display's background
illumination switches off automatically.
3.4 Displays / Menus / Dialogs
One note at the outset:
The following section describes the menu assistance and operation of all gas-
net devices in general.
Where appropriate, individual subjects have been illustrated with examples.
These examples refer to currently available device types. Therefore, it may
happen that a special menu illustrated in an example does not exist in your gas-
net device type.
In accordance with the gas-net concept, however, the operating mechanisms
generally described here function in all devices in the same way.
Each module has a main display in which all important current values are
indicated.
For example: Among others, the gas-net Q1 contains the gas-lab Q1 and
Monitoring modules. The main display of the gas-lab Q1 module shows
the current measurements, whereas the main display of the Monitoring
module indicates the error listing.
The main display of the first module is also the basic display of the device, i.e.
the display that is invoked automatically if there has been no keystroke for about
30 minutes.
For example: The basic display of the gas-net Q1 is the main display of
the gas-lab Q1 module.
A display serves to present values.
If there are more entries than can be made visible at once, little scroll arrows on
the right side indicate whether or not you may scroll upwards or downwards.
