Technical data
8.1 Measuring principle
The converter is based on a 16-bit microprocessor. The internal software uses a real-time
operating system, allowing multiple tasks to be carried out in "parallel". One process takes care
of the display and the dialogs, one process is dedicated to handle each attached sensor, and one
task is taking care of all the housekeeping.
After power up, the software will initialize the functionality and data structures, reading
information from a non-volatile memory. A welcome message is displayed for about ten
seconds, showing the software version and serial number of the converter. The unit will then
start looking for sensors it already knows, and if found initialize them to start measuring. Twice
a minute the unit looks for unknown sensors. If one is found, the converter will find out the type
and serial number and open up a dialog box to let the operator select what slot to use for the new
sensor.
