What does 'Or Ur' mean on bluelab Combo Meter Measuring Instruments while in temp mode?
If your bluelab Measuring Instruments displays 'Or Ur' while in temperature mode, it indicates an over-range or under-range temperature. This means the solution temperature is either >51 °C / 122 °F or
What does 'Or Ur' mean on bluelab Measuring Instruments while in pH mode?
If your bluelab Measuring Instruments displays 'Or Ur' while in pH mode, it indicates an over-range or under-range pH. This means the solution pH is > 14.0 or < 0.0. Check the pH probe connection. The pH probe could be faulty, or the Combo Meter could be wet inside.
