What to do if Hanna Instruments HI 3512 Measuring Instruments display shows blinking full scale value?
- CCynthia GordonAug 9, 2025
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.
