Menu: MCS100FT/Adjustment/Parameter/IR components
This menu serves to set the parameters for the adjustment of the IR components.
The list shows the active components.

An input screen is shown after touching a field.
Designation Remark
Offset Null Prior To Adjustment
(1:Yes, 2:No)
Checkmark: Yes, duration approx. 20 minutes.
H2O Component Index Index (“Number”) of the measured value for H
2
O. Preset.
No. Of Offset Null Samples Number of measured values when adjusting the zero point.
No. of Adjustment Samples Number of measured values when adjusting the reference point.
No. of Samples for Stability
Condition
Number of measured values for the stability check
Adjustment Tolerance When the difference of two successive adjustments is greater than the
entered value (in %):
The adjustment factor is not set and an error message output.
Max. Zero Offset Maximum allowed offset during reset to zero.
The reset to zero is not saved if the difference during reset to zero is
larger than the specified offset.
The unit is the unit of the respective component.
Max. Water Absorbance When the absorbance entered is exceeded during zero adjust: Zero
adjust is aborted and an error message shown.
Max. Water Absorbance
Change
Criterion for stability of gas during gas feeding:
Difference of H
2
O absorbance.
If, during leveling out, the value is below this “difference” between two
measurements, the gas has “leveled out”.
