If the Hach Laboratory Equipment displays ERR10, indicating a system voltage out of range, turn the instrument off and then back on.
What to do if Hach Laboratory Equipment shows ERR09?
If the Hach Laboratory Equipment displays ERR09, which means printer time out error, check the following: 1. Ensure the external printer is correctly connected. 2. Confirm the external printer is selected (online).
What to do if Hach Laboratory Equipment shows ERR06?
If the Hach Laboratory Equipment displays ERR06, indicating that A/D is under the range, make sure that no object is in the light path.
What to do if Hach Laboratory Equipment shows ERR05?
If the Hach Laboratory Equipment displays ERR05, indicating that A/D is over the range, ensure that the light shield is closed.
What to do if Hach Laboratory Equipment shows ERR02?
If the Hach Laboratory Equipment displays ERR02, it could be due to these reasons: * Two calibration standards have the same value. * The difference between two calibration standards is less than 60.0 NTU. * The turbidity of Standard 1 is too low (less than 10 NTU). To solve this problem: 1. Check the preparation of the standards. 2. Redo the calibration. Note: If the sample cell diameter is less than 25 mm, ignore ERR02.

What to do if Hach Laboratory Equipment shows ERR01?
If the Hach Laboratory Equipment displays ERR01, it means the turbidity of the dilution water is greater than 0.5 NTU. To resolve this: Start the calibration again using dilution water with lower turbidity. Note: If the sample cell diameter is less than 25 mm, ignore ERR01. Press UNITS/Exit to return to measurement mode.
What to do if Hach Laboratory Equipment shows ERR07?
If the Hach Laboratory Equipment displays ERR07, indicating a light leak, follow these steps: 1. Ensure that the cover for the sample cell compartment is securely closed. 2. Turn the instrument off and then back on.
What to do if Hach Laboratory Equipment shows ERR03?
If the Hach Laboratory Equipment displays ERR03, which indicates a low light error, try the following: 1. Re-insert the sample into the instrument. 2. Verify that the lamp is illuminated. 3. Ensure there are no obstructions in the light path. 4. Dilute the sample if necessary. Note: If this error happens when using a filter assembly other than the USEPA filter assembly, you should not use the filter assembly for turbidity measurements.
