Assigning correction of cross-interference with a constant

Procedure with OXYMAT 7
1. Component > Main menu > "2. Settings" > "10. Correction of cross-interference" > "2
Constant"
2. Enable/disable correction of cross-interference: "Correction of cross-interference"
parameter field.
Authorize access with corresponding PIN, if necessary.
3. Enter interference gas concentration already known: "Interference gas concentration"
parameter field.
4. Define the coefficient.
Note
Operator control options
Refer to the coefficients stored in the device-internal reference table or enter a coefficient
manually.
Using the coefficients of the reference table:
– Select the interference gas you want to correct: "Interference gas reference table"
– Select the corresponding gas.
Using manually specified coefficient:
– "Interference gas reference table" parameter field: Set "User-defined" value.
– Enter coefficient already known manually: "Coefficient" parameter field.
5. Only with activated process tag switchover: Change the process tag assignment.
– Check the displayed process tag assignment.
– "Process tag" > "Change" parameter field.
– Activate the corresponding process tags that are to be integrated into the correction of
