What to do if my Hanna Instruments Measuring Instruments shows a blinking battery symbol?
If your Hanna Instruments Measuring Instruments unit is displaying a blinking battery symbol, this indicates a low battery level. Replace the battery to resolve this issue.
What to do if Hanna Instruments Measuring Instruments shows “WRONG” & blinking dashes?
If your Hanna Instruments Measuring Instruments is displaying “WRONG” & blinking dashes, this indicates a calibration error. Check your buffer solution or replace the pH electrode.
Why is my Hanna Instruments Measuring Instruments reading fluctuating up and down (noise)?
If the reading on your Hanna Instruments Measuring Instruments is fluctuating up and down, it could be due to a clogged or dirty junction, or a low electrolyte level in refillable electrodes. To resolve this, soak the electrode tip in warm HI7082 solution for one hour, then rinse it with distilled water. If necessary, refill with fresh electrolyte.
How to fix slow response or excessive drift in Hanna Instruments Measuring Instruments?
If you're experiencing a slow response or excessive drift with your Hanna Instruments Measuring Instruments, it might be due to a dirty pH electrode. Soak the electrode tip in HI7061 solution for 30 minutes to clean it.
What does “Clr” message mean on Hanna Instruments Measuring Instruments?
The “Clr” message on your Hanna Instruments Measuring Instruments indicates that default pH calibration values have been loaded. Perform a pH calibration to resolve this.
