6.5 Sample-dependent maintenance procedures
6.5.1 Exchanging the solutions C1 calibration solution 1, C2 calibration
solution 2, and C3 fluid packs
C1 calibration solution 1 and C2 calibration solution 2
Depending on the rate of measurement and/or the on-board stability, these solutions
should be exchanged every 2-4 weeks. The screen displays the appropriate information.
The bottles of C1 and C2 solution must always be exchanged simultaneously.
Fluids remaining in the bottles may never be mixed together because this may result
in calibration errors!
Reuse of this bottle can lead to errors during calibration! Insert another bottle that
has not yet expired.
C3 fluid pack
Depending on the rate of measurement and/or the on-board stability, this fluid pack should
be exchanged every 4-6 weeks. The screen displays the appropriate information.
Reuse of this bottle can lead to errors during calibration! Insert another bottle
that has not yet expired.
It contains the following solutions:
• Solution for calibrating the P O
2
zero point
• Solution for conditioning the Na
+
electrode
• Cleaning solution
• Reference solution
