5.13 Service Commands
The device will write down to the Flash-ROM its maximal/minimal internal temperature, its runtime
accumulated and the longest runtime without restart. They can be inquired with GSP. The device will
answer with:
SP<runtime in hours> <max. runtime without reset in hours> <min. temperature>
<max. temperature>
As Flash-ROM is limited in its erase-write-cycles writing takes place under the following conditions:
• Every two hours.
• If the internal temperature gets over 55°C (131°F).
• With the set command.
Unfortunately there is the need to have a set command for it (a new firmware boot-loaded may change
its memory address.):
SP <runtime in hours> <max. runtime without reset in hours> <min. temperature>
<max. temperature>
The set command returns immediately but it might take up to 10 seconds that the save takes place.
It can be used in calibration mode only.
5.14 The Window Transmission
The device has three transmission commands. The first allows the user to adjust for additional windows.
The remaining two are used to allow the change of the standard window in the field. In detail:
• TA: for an additional window
• %TA: gives the transmission of the window that was used for calibration, used to generate the
temperature tables
• TAW: gives the transmission of the spare part window.
For the first window is: %TA == TAW.
