To Next PageTo Next PageWhy Hanna Instruments Measuring Instruments meter fails to calibrate or gives erroneous results?
If your Hanna Instruments Measuring Instruments meter isn't calibrating or is showing incorrect results, the pH electrode may be defective. Replace the electrode and repeat the pH calibration to resolve this issue.
What to do if Hanna Instruments Measuring Instruments meter is slow in responding or gives erroneous readouts?
If your Hanna Instruments Measuring Instruments meter is responding slowly or giving incorrect readings, the electrode may not be working properly or the diaphragm could be clogged. Try leaving the electrode in a storage solution after cleaning the diaphragm. If this doesn't fix the problem, replace the electrode and re-calibrate the pH scale.
What does "Err1" (for HI8417) "E 1" (for HI8520/ HI8521) on Hanna Instruments Measuring Instruments mean?
If you see "Err1" (on HI8417) or "E 1" (on HI8520/HI8521) on your Hanna Instruments Measuring Instruments display, it means the reading is out of range on the pH scale. To fix this: a) Verify the pH electrode is connected. b) Ensure the pH sample is between 0 and 14 pH. c) Check the electrode's filling electrolyte level and its overall condition.
What to do if Hanna Instruments HI8417 Measuring Instruments meter does not accept the 2nd buffer solution?
If your Hanna Instruments Measuring Instruments meter isn't accepting the second buffer solution, it could be due to a defective pH electrode or a bad buffer solution. First, try cleaning the electrode. If that doesn't work, replace the electrode and re-calibrate the pH. Also, make sure you are using a fresh buffer solution.
What does "Err3" (for HI8417) "E 2" (for HI8520/ HI8521) on Hanna Instruments Measuring Instruments mean?
If your Hanna Instruments Measuring Instruments shows "Err3" (for HI8417) or "E 2" (for HI8520/ HI8521), it indicates an out-of-range temperature in °C. Verify the temperature probe is connected. Ensure the temperature is within -10/125°C for HI8417 or -10/100°C for HI8520/HI8521.
What does "Err4" (for HI8417) "E 4" (for HI8520/ HI8521) on Hanna Instruments Measuring Instruments mean?
If you see "Err4" (on HI8417) or "E 4" (on HI8520/ HI8521) on the display of your Hanna Instruments Measuring Instruments, it means an erroneous buffer solution was used for offset calibration. Ensure you are using a pH 7 buffer solution and replace it if necessary.
What does "Err5" (for HI8417) "E 5" (for HI8520/ HI8521) on Hanna Instruments Measuring Instruments mean?
If your Hanna Instruments Measuring Instruments displays "Err5" (for HI8417) or "E 5" (for HI8520/ HI8521), it indicates that an incorrect buffer solution was used for slope calibration. Make sure you're using the correct pH buffer solution (4.01, 9.18, or 10.01 pH) for slope calibration.
Why does Hanna Instruments HI8417 Measuring Instruments reading drifts?
If the reading on your Hanna Instruments Measuring Instruments is drifting, it's likely that the temperature is not stable. Allow more time for thermal equilibrium to be reached.
What does "Err2" (for HI8417) "E 3" (for HI8521) on Hanna Instruments Measuring Instruments mean?
If your Hanna Instruments Measuring Instruments is showing "Err2" (for HI8417) or "E 3" (for HI8521), it indicates that the mV is out of range. Verify the temperature probe is connected and ensure the mV is within the ±1999 range.
What to do if Hanna Instruments HI8417 has a defective electrode?
If you suspect a defective electrode in your Hanna Instruments Measuring Instruments, replace the electrode and re-calibrate the pH scale.
