Maintenance actions
Perform an air/water calibration
f Utilities > Maintenance > Abs. Air/Water Calibration
The absorbance photometer calibration determines the air/water correction values
that are needed for result calculation. In addition, the obtained absorbance values for
an empty cuvette at each wavelength are used as a reference for the cuvette blank
check.
Operator time Approximately 5 minutes.
Prerequisites The system must be in Standby status.
Tools and materials required m 2 cuvette segments with empty cuvettes
a To perform an air/water calibration
1 Choose Utilities > Maintenance > Abs. Air/Water Calibration.
2 Press .
Your are asked to insert a cuvette segment with empty cuvettes.
3 Open the main cover.
4 If there is a segment in the cuvette ring remove it and check whether there are
used cuvettes.
If all cuvettes of this segment are empty, you can reinsert it.
5 Place a cuvette segment with empty cuvettes on the cuvette ring.
6 Press .
Your are asked to insert a second cuvette segment with empty cuvettes.
7 If there is a segment on in the cuvette ring remove it and check whether there are
used cuvettes.
If all cuvettes of this segment are empty, you can reinsert it.
8 Place the cuvette segment with empty cuvettes on the cuvette ring.
9 Close the main cover.
10 Press .
The system performs the calibration measurements. (It first measures all cuvettes
empty, pipettes water in the cuvettes, and measures them again.)
A message will inform you when the measurements are complete.
11 Scroll to display the results, if required.
12 Check the Outlier statistics.
