Note
For span point calibration it is generally a good idea to use 80% of the reporting
range for that channel. For instance, if the reporting range of the instrument is
set for 5%, the proper span gas would be 4%

9.1.3. DATA RECORDING DEVICES
A strip chart recorder, data acquisition system or digital data acquisition system
should be used to record data from the serial or analog outputs of the T802.
