9.2 Main control software.
[Back to contents]
When the main control software is loaded, it will run and display the following screen:
It is possible to run in simulation mode, where the optical output from the system is disabled – but with all other
functions enabled. There is a 5 second opportunity to press the Simulation mode button as the software starts.
The System information box will display system messages and information.
The Doppler parameters are shown for information only, and it is suggested that the 1024 number be left by default.
The Pre switch on checks will commence once the software is started, either immediately after it loads, or when re-
starting after previously stopping. To start the software manually if it is in a stopped state, press the run arrow
at
the top left.
The Thermo-electric cooler (TEC) status will be displayed if the system has the active or extended temperature option
fitted.
All the red lights in the 'Pre switch on checks' panel should turn green if the system is ok. If a failure occurs, then the
software may stop and an appropriate message should appear in the System information box. Allow around 20
seconds for the tests to complete.
Once the tests are complete, the previous settings will be loaded into all the parameter boxes and there is the option
to change any of the ones that have a yellow. The system will auto accept in 6 minutes if the accept button is not
pressed. This is a system recovery feature and makes sure that if the system comes on after power failure (and is
allowed to boot to the desktop, and run this software from the startup directory), then it progresses past this point. The
Abort button can be used before the accept button is pressed, or before the system auto-starts at this point to stop
the software from fully starting.
Measurement range - The system's maximum measurement range is displayed in metres and range gates. The max
desired measurement range (gate number) is selected by entering it into the yellow box. [Click outside the box, or
press Enter to enter the number].
Lowering the maximum measurement range will reduce the processed data file size.
