Correction of cross-interference is only meaningful if the effect of the interfering gas is lower
than the expected O
2
concentration.
Correction of cross-interference is not effective during a calibration procedure. It is active
again when calibration has been completed and the device has returned to measuring mode.
Press the first softkey. The following function screen appears on the display.
By pressing the first softkey you now select the type of influence of an interfering gas. The
following distinctions are possible:
● No correction of cross-interference
● Correction of cross-interference with constant influence of interfering gas
● Correction of cross-interference with variable influence of interfering gas via analog input
● Correction of cross-interference with variable influence of interfering gas via ELAN

With softkey 2, you can set whether the correction of cross-interference should only apply to
certain measuring ranges.
Under
"Interference"
, enter the value of the zero offset.
