Why is the "°C" blinking on my Hanna Instruments Measuring Instruments display?
If the "°C" is blinking on your Hanna Instruments Measuring Instruments display, it means no temperature probe is attached. Make sure the temperature probe is attached properly.
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.
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.
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.
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.
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 'Eb' mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows 'Eb', it indicates a low battery. Replace the battery.
What does 'Er' mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows 'Er', it indicates an over-range condition. Repeat conditioning.
What to do if my Hanna Instruments Measuring Instruments does not work with the temperature probe?
If your Hanna Instruments Measuring Instruments does not work with the temperature probe, the probe may be out of order. Replace the probe.
What does "Er-4" mean on my Hanna Instruments Measuring Instruments display?
If your Hanna Instruments Measuring Instruments display shows "Er-4", it indicates an erroneous pH 4 buffer solution was used for slope calibration, or the pH electrode is out of order. Use fresh pH 4 buffer solution. If the problem persists, replace the electrode.
