The FIDAMAT 6 offers the option of a manual or automatic calibration (function 24). The
latter is only possible with an optional board which contains an additional eight binary
outputs and eight relay outputs.
The setpoints for the zero and span calibrations are entered using function 22.
Calibrate using calibration gases which are very close to the sample gas in composition and
concentration. If the task is to measure hydrocarbons in nitrogen, you should also use
hydrocarbons in nitrogen as the calibration gas. If you use, for example, propane in synthetic
air instead, the measurement is falsified by the response factor of methane with respect to
propane and by the oxygen error.
