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.
