What to do if Hach LZV902 Measuring Instruments displays 'Concentration too high!'?
If the Hach Measuring Instruments displays 'Concentration too high!', it means the calculated concentration is higher than 999999. Dilute the sample and measure again to resolve this issue.
What to do if Hach LZV902 Measuring Instruments says 'Over measuring range'?
If your Hach Measuring Instruments indicates that you are over the measuring range, it means the measured absorbance is above the calibration range of the test. To fix this, dilute the sample and measure it again.
What does 'Fault Clean cuvette!' mean on Hach Measuring Instruments?
If the Hach Measuring Instruments displays 'Fault Clean cuvette!', it indicates that the cuvette is dirty or there are undissolved particles in it. Clean the cuvette and allow any particles to settle before proceeding.
What to do if Hach LZV902 Measuring Instruments says 'File for instrument update is faulty'?
If the Hach Measuring Instruments indicates that the file for the instrument update is faulty, it means there was an error during the update. Save the update file again and repeat the procedure.
What does 'Under measuring range' mean on Hach Measuring Instruments?
When 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 reading range or use a cuvette with a longer path length.
What to do if Hach Measuring Instruments displays 'Fault Barcode check number? Please update program data!'?
If the Hach Measuring Instruments displays 'Fault Barcode check number? Please update program data!', it indicates a deviation from the stored data. Update the program data to resolve this issue.
What to do if Hach LZV902 Measuring Instruments says 'USB memory stick is not connected'?
If the Hach Measuring Instruments displays 'USB memory stick is not connected', it means that an update is not possible. Check the USB memory stick to ensure it is properly connected.
What to do if Hach LZV902 shows 'Too much ambient light' error?
If the Hach Measuring Instruments display an error indicating too much ambient light, it means the instrument sensors are detecting excessive light. Decrease the ambient light by moving the instrument into the shade, avoiding direct sunlight, or simply closing the lid.
Why is Hach LZV902 Measuring Instruments recommending a Full System Check?
If the Hach Measuring Instruments recommends executing a Full System Check, it is because the check of the air values failed. Switch the instrument off and then back on again. If the system check is still not successful, contact technical support.
What does 'Error Selfcheck stopped. Hardware error' mean on Hach Measuring Instruments?
If the Hach Measuring Instruments displays 'Error Selfcheck stopped. Hardware error', it indicates an electronic defect. Contact technical support and provide the error number.
