What to do if Hanna Instruments HI 3512 Measuring Instruments display shows blinking full scale value?
If your Hanna Instruments Measuring Instruments display shows a blinking full scale value, it indicates that the reading is out of range. Ensure that your sample is within the measurable range. Also, check the electrolyte level and overall electrode status. Recalibrate the meter and verify that the range is not fixed or locked.
Why does my Hanna Instruments Measuring Instruments display show “Clean electrode“ blinking?
If your Hanna Instruments Measuring Instruments displays “Clean electrode“ blinking, it means a difference between the new and previous calibration has been detected. You should clean the electrode and recalibrate. If the problem continues, check the buffer solutions.
Why am I getting error messages during pH calibration of my Hanna Instruments HI 3512 Measuring Instruments?
If you are getting error messages during pH calibration with your Hanna Instruments Measuring Instruments, the buffer might be wrong or contaminated, or the electrode could be dirty or broken. Check that the buffer solution is correct and fresh, and that the meter is set for the correct buffer.
Why is my Hanna Instruments HI 3512 reading fluctuating?
If your Hanna Instruments Measuring Instruments reading fluctuates up and down (noise), this may be due to a clogged or dirty junction, low electrolyte level (for refillable electrodes only), or the EC probe not being properly connected. Clean the electrode. If you have a refillable electrode, refill it with fresh electrolyte. Ensure the probe is properly inserted.
What does the symbol in front of temperature reading on Hanna Instruments HI 3512 mean?
If your Hanna Instruments Measuring Instruments shows a symbol in front of the temperature reading, it means the temperature probe is out of order or missing. Replace the temperature probe or check its connection.
