4. THE SERVICE PROGRAM
The instrument calculates the gas concentration from the measured signal, which
depends on several process parameters. The instrument must therefore be
configured for the specific installation. With the service program the user
communicates with the instrument and changes installation or process relevant
settings. With a PC connected to the instrument via a standard serial
communication port the operator can perform the following major tasks:
1. Monitor the measured concentration and the laser beam transmission;
2. Plot the measured concentration as a function of time;
3. Log the concentration and other control parameters to a file;
4. Display the measured signal;
5. Save the measured signal and other control parameters to a file;
6. Observe and erase the instrument error logging;
7. Configure the 4-20 mA process temperature and pressure inputs;
8. Configure the 4-20 mA measurement output;
9. Change the measurement averaging time;
10. Set the gas alarm level;
11. Set the optical path parameters;
12. Change the concentration unit;
13. Change the format of the displayed concentration;
14. Change the instrument clock time;
15. Calibrate the instrument;
16. Save all instrument parameters to a file;
17. Restore the instrument parameters from a file.
18. Configure the (optional) Ethernet connection
Through different menus the necessary installation parameters may be set. After
setting the necessary parameters the PC is no longer needed. The
SERVOTOUGH LaserExact has all the parameters stored in the internal memory.
The PC can therefore be disconnected and the SERVOTOUGH LaserExact can
be turned off and on without resetting the parameters.
4.1 Software start-up
After starting the program a welcome screen will display a selection of instrument
