Adjustment process
1
Enter the password,
see “Entering the password (PAS)”, page 37

Access to the adjustment functions is open for 30 minutes after the password is
entered. Functions in progress are not interrupted after expiry of 30 minutes. Enter the
password again to execute more password-protected functions.
3
Make sure that no error messages are active as these could affect adjustment.
Malfunction messages,
see “Display of active and undeleted errors (ERR)”, page 36
.
4
Make sure that the ambient parameters of the adjustment environment have been set
before adjustment.

concentrations of the calibration gas.
Calibration gases have a humidity of 0 g/m

This ends the one-point adjustment.
●
The reference concentration used determines whether the gain or offset parameter
value is changed.
– Change to the offset value: Oxygen concentration < 10.5% O
2
– Change to the gain value: Oxygen concentration > 10.5% O

●
Two-point adjustment: Always returns new gain and offset values.
