What to do if wtw Measuring Instruments display 0000FFFFLLLL Indication range exceeded?
- JJennifer WoodardAug 25, 2025
If your wtw Measuring Instruments display '0000FFFFLLLL Indication range exceeded', it suggests a problem with the pH electrode. The issue might be that the electrode is not immersed, the cable is broken, the electrolytic gel has dried out, there's an air bubble in front of the diaphragm, or there's air in the diaphragm. To solve this: * Immerse the electrode into the sample solution. * If needed, exchange the electrode. * Remove any air bubbles. * Suck off air or moisten the diaphragm.
