First step: NULL CALIBRATION

 Disconnect the sensor from the BNC connector ->RETURN

 The NULL CALIBRATION is started

 If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Reconnect the oxygen sensor to the running ProfiLux 4.

 Wait at least 30 minutes to continue with step two

Second step: AIR CALIBRATION

The Air calibration is only possible if a Null calibration has been performed successfully at

least once. Before the Air calibration, the sensor must be connected to the ProfiLux 4 for at

least 30 minutes!

 Select Air calibration ->RETURN

 Select the Temperature compensation and proceed accordingly

 Select the Salinity compensation and proceed accordingly

 Enter the temperature of the air at the calibration location ->RETURN

 Keep the sensor about 1 cm (0.39”) above the water and do not touch the surface of

the water with the sensor

 Start the measurement with ->RETURN

 If no errors have occurred, save the calibrated values by selecting Yes and confirm

with RETURN

 Check the calibration as described below

The Oxygen sensor is now ready for use. Based on your calibration, ProfiLux 4 can now

determine the dissolved oxygen.

5.9.9 Control of Sensor calibration

Please check at all calibration points whether the correct value is displayed:

Note

During the calibration measurement, 2 numbers can be seen in the lower

line. The left number indicates the maximum remaining time in seconds.

If the measured value has not stabilized sufficiently after this time has

elapsed, a faulty sensor is emitted and the calibration is interrupted.

The right number shows the measured value in an internal representation.

ProfiLux 4 detects automatically if this value has stabilized and then

terminates the measuring process.
