Analyse of the calibration results
During the calibration process, two parameters are measured, zero of the analyser and the
sensitivity (voltage variation in mV for 1% of gas variation). The traffic lights indicate the
deviation of these parameters relative to the factory (reference) calibration.
Deviation less than 5%. The calibration is good and the system can be used.
Deviation between 5 and 10%. The calibration is acceptable but a verification
of the system is recommended.
Deviation greater than 10%. The calibration is not acceptable.
A verification of the system is required.
A graphic indicates also the reaction in real time of the analysers. The traces should be
similar to the image below.
