Calibration of the Uras26 with internal cross-sensitivity correction
Possible electronic cross-sensitivity corrections by other sample compo-
nents measured by Uras26 are disabled for the calculation of the calibration.
The following information should therefore be noted in particular:
Zero-point calibration
All the sample components must always be calibrated in the following se-
quence for the zero-point calibration:
• firstly the sample component which is not corrected,
• then the sample component which is affected by the smallest number of
corrections,
• up to the sample component which is affected by the largest number of
corrections.
End-point calibration
All the sample components must also always be calibrated in the end-point
calibration. Here, a corrected sample component may only be calibrated
using a test gas which does not contain any components which cause
cross-sensitivity, i.e. which only consists of the sample component and an
inert gas, e.g. N
2
.
