Diagnostics of gas measurements and autocalibration data
Diagnostics data of gas measurements and gas analyser calibration data are recorded with Gadiag-program running on 'Gaslog' computer.
The sensors are connected to three Nokeval serial transmitters.
The channel list is given here. In the file the column is channel number +1.
