What to do if absorbance is greater than 3.5 on Hach Measuring Instruments?
If your Hach Measuring Instruments displays 'Absorbance > 3.5!', it means the measured absorbance exceeds 3.5. To resolve this, dilute the sample and repeat the measurement.
What to do if Hach DR 2800 Measuring Instruments shows concentration too high?
If the Hach Measuring Instruments displays 'Concentration too high!', it means the calculated concentration is higher than 999999. To fix this, dilute the sample and repeat the measurement.
What to do if Hach DR 2800 Measuring Instruments selfcheck stopped?
If the Hach Measuring Instruments displays 'Error Selfcheck stopped. Please check the lamp. Please close the lid', it means the Self Check Test stopped while starting the instrument. Check the lamp and replace it if necessary. Close the lid and press START AGAIN.
How to fix error clean cuvette on Hach DR 2800 Measuring Instruments?
If your Hach Measuring Instruments displays 'Error Clean Cuvette', it indicates that the cell/cuvette is soiled or there are undissolved particles in the cuvette. Clean the cuvette and allow the particles to settle to resolve this issue.
Why does Hach DR 2800 Measuring Instruments show error barcode control number?
If the Hach Measuring Instruments displays 'Error Barcode control number? Please update program data!', it means there is a discrepancy between barcode test data and stored information. Data updating is required to resolve this issue.
Why does Hach Measuring Instruments say error program not available?
If the Hach Measuring Instruments displays 'Error Program not available. Please update program data!', it means the Barcode test is missing. Data updating is the suggested solution.
