electrodes, do the following:
Step Action
1. The pH electrode only:
Clean the electrode, using a cotton swab moistened with Cleaning
Solution.
2. Check the measuring chamber for clots: clean the measuring chamber
with a cotton stick moistened with distilled water. Make sure that no
cotton fibers are left in the measuring chamber.
3. Replace the electrode membrane (not the pH electrode).
4. Call a 2-point calibration. If the error persists, replace the electrode.
If an error has occurred on two or more parameters, troubleshoot the reference
electrode.
