Appendix C - Calibration of an oxygen sensor
The oxygen sensor is an electrochemical sensor. To function properly, electrochemical sensors have to be recalibrated at regular
intervals. This is best done weekly, but at least monthly.
There are two types of calibration:
• Calibration with a reference fluid
and
• Calibration in the air.
Press in the measurement display on <Menu> and <Sensorlist> on the main menu, then on the desired sensor and then on <Calibra-
tion>.
To protect against misuse there is a password protection set up.
The four-digit code number is in the information sheet. Continue with
Calibration with a reference fluid
Immerse the oxygen sensor in the reference fluid and wait until the displayed value is stable.
Calibration in air
Hold the oxygen sensor approximately 15 minutes to the air.
Continue with
Enter the oxygen content of the
reference fluid.
Continue with
Check whether the measured value
agrees with the reference value.
