What to do if Hach Measuring Instruments shows error E7 (light leak)?
If the Hach Measuring Instruments displays error code E7, it indicates a light leak. Ensure the lid is closed properly before pressing the READ key to take a measurement.
What to do if Hach 2100P Measuring Instruments shows error E3 (low light)?
If the Hach Measuring Instruments displays error code E3, which indicates a low light error, try re-reading the measurement. Also, inspect the lamp and check for any obstructions in the light path. Dilution of the sample might also be necessary.
What to do if Hach 2100P shows error E6 (A/D underrange)?
If the Hach Measuring Instruments displays error code E6, which indicates an A/D underrange, first ensure that the lid was not open during the reading, and then re-read the sample. Also, check for any obstructions in the light path. If the problem persists, contact Hach Service.
What to do if Hach 2100P shows error E5 (A/D overrange)?
If the Hach Measuring Instruments displays error code E5, which indicates an A/D overrange, check for any obstructions in the light path and call Hach Service.
How to fix Hach Measuring Instruments error E8 (bad lamp circuit)?
If the Hach Measuring Instruments displays error code E8, which indicates a bad lamp circuit, try reinserting the lamp leads at the terminal block, ensuring that the lead ends are not touching each other. If the error persists, contact Hach Service.
What to do if Hach 2100P shows error E4 (EEPROM malfunction)?
If the Hach Measuring Instruments displays error E4, indicating an EEPROM malfunction, press the I/O button. If E4 reappears, call Hach service. If CAL? appears, recalibrate the instrument.
Why does my Hach Measuring Instruments show error E2, and how can I fix it?
Error E2 on the Hach Measuring Instruments indicates that two standards have the same value or their difference is less than 60 NTU, not all standards were read during the calibration, or standard 1 is too low (
How to fix Hach 2100P error E1 related to dilution water?
If the Hach Measuring Instruments displays error code E1, it means the dilution water is ? 0.5 NTU. You should start the calibration over with better quality dilution water. Alternatively, use a membrane filter to filter the water before use.
