Calibration reset 
What does the calibration reset do? 
A calibration reset returns the analyzer module’s calibration to basic calibra-
tion values. Furthermore, the offset drift and amplification drift are elec-
tronically returned to basic calibration values (see page 274). 
Note: The absolute offset and amplification drift values are calculated cumu-
latively starting from the last basic calibration. The relative offset and ampli-
fication drift values are calculated between the last and next to last automatic 
calibration. The absolute and relative offset and amplification drift values can 
be viewed in the MENU 
→ Diagnostic/Information → Module specific 
→ Status menu item. 
When should a calibration reset be performed? 
A calibration reset should be performed if an analyzer module can no longer 
be calibrated by normal means. A possible cause of this is calibration of the 
analyzer module with the wrong test gases.

NOTE 
The analyzer module should be calibrated after a calibration reset.
