What to do if Hach Measuring Instruments shows 'Too much ambient light!'?
If the Hach Measuring Instruments indicates 'Too much ambient light!', it means the sensors are detecting excessive ambient light. To resolve this, reduce the ambient light by avoiding direct sunlight and ensure the lid is closed.
What to do if Hach Measuring Instruments displays 'Absorbance > 3.5!'?
If the Hach Measuring Instruments shows 'Absorbance > 3.5!', it means the measured absorbance exceeds 3.5. The solution is to dilute the sample and repeat the measurement.
What to do if Hach Measuring Instruments displays 'Concentration too high!'?
If the Hach Measuring Instruments indicates 'Concentration too high!', it means the calculated concentration is higher than 999999. You should dilute the sample and repeat the measurement.
What to do if Hach Measuring Instruments says 'Over measuring range'?
If the Hach Measuring Instruments displays 'Over measuring range', it means the measured absorbance is above the calibration range of the test. Dilute the sample and repeat the measurement to resolve this.
How to fix self-check error on Hach Measuring Instruments with lamp issue?
If the Hach Measuring Instruments displays 'Error Selfcheck stopped' with a lamp issue, it means the self-check test stopped while starting. Check the lamp and replace it if necessary. Also, ensure the lid is closed, then press 'Start Again'.
What to do if Hach Measuring Instruments displays 'Color = ***'?
If the Hach Measuring Instruments displays 'Color = ***', it means the spectrum locus is outside the measuring range. Dilute the sample or select an appropriate color scale.
What to do if Hach Measuring Instruments displays 'Error Selfcheck stopped. Please remove the cuvette Please close the lid.'?
If the Hach Measuring Instruments displays 'Error Selfcheck stopped. Please remove the cuvette Please close the lid.', it means the self-check test stopped while starting. Remove the cuvette/sample cell from the cell compartment and press OK.
Why does Hach Measuring Instruments show 'Negative result!'?
If the Hach Measuring Instruments shows 'Negative result!', it means the calculated result is negative. Check the concentration of the sample.
How to use adapter Z with Hach Measuring Instruments?
Adapter Z is required for measurements with 11mm round cells. Insert the adapter Z into cell compartment #2 and press OK.
What to do if Hach Measuring Instruments says 'Under measuring range'?
If the Hach Measuring Instruments displays 'Under measuring range', it means the measured absorbance is below the calibration range of the test. If possible, select a test with a lower measurement range or use a cuvette/sample cell with a longer path length.
