Why does my Hanna Instruments Measuring Instruments fail to calibrate?
Your Hanna Instruments Measuring Instruments may fail to calibrate due to an erroneous buffer solution. Check the buffer solution and replace it if necessary. Another possible cause is an out-of-order pH electrode; in this case, replace the pH electrode.
What does "Er-7" mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows "Er-7", it indicates an erroneous pH 7 buffer solution was used for offset calibration, or the pH electrode is out of order. Use fresh pH 7 buffer solution. If the issue continues, replace the electrode.
What does "E5" mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows "E5", it indicates that an erroneous buffer solution was used for slope calibration, or the pH electrode is out of order. Use fresh buffer solution. If the issue persists, replace the electrode.
What does "E4" mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows "E4", it means an erroneous buffer solution was used for offset calibration, or that the pH electrode is out of order. Make sure the buffer solution used is pH 7 and replace it if necessary. If that doesn't solve the problem, replace the pH electrode.
What does "pH----" mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows "pH----", it indicates an out-of-range pH scale. To resolve this: a) Check the calibration. b) Ensure that the pH value is between 0 and 14. c) Check the level of electrolyte and the state of the electrode itself.
What does "E1" mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows "E1", it indicates an out-of-range pH scale. To resolve this: a) Check the calibration. b) Ensure that the pH value is between 0 and 14. c) Check the level of electrolyte and the state of the electrode itself.
Why does the reading drift on my Hanna Instruments Measuring Instruments?
Drifting readings on your Hanna Instruments Measuring Instruments can be caused by a clogged or out-of-order pH electrode. Follow the cleaning procedure and replace the pH electrode if necessary.
Why is my Hanna Instruments Measuring Instruments slow in responding?
If your Hanna Instruments Measuring Instruments is slow in responding or gives faulty readouts, the electrode may not be working, or the reference junction may be clogged. Leave the electrode in a storage solution after cleaning the junction. If the problem persists, replace the electrode.
What to do if my Hanna Instruments Measuring Instruments does not accept the 2nd buffer solution?
If your Hanna Instruments Measuring Instruments does not accept the 2nd buffer solution, it might be due to an erroneous buffer solution used for slope calibration. Check the buffer solution and replace it if necessary. Alternatively, the pH electrode may be out of order. In this case, follow the cleaning procedure; if this doesn't work, replace the electrode.
