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.
