Why am I getting a low light error (Err03) on my Hach 2100N?
An Err03 error on your Hach Measuring Instruments indicates a low light error. First, reinsert the sample. Then, check that the lamp is on and that there are no obstructions in the light path. If needed, dilute the sample.
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.
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 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 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. Press UNITS/Exit to return to measurement mode.
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 is a system loop test error (Err11) on Hach 2100N Measuring Instruments?
An Err11 error indicates a system loop test error. Try switching the Hach Measuring Instruments off and back on using the I/O switch.
What causes a printer timeout error (Err09) on Hach 2100N Measuring Instruments, and how to fix it?
If you're experiencing a printer timeout error (Err09) with your Hach Measuring Instruments, verify that the external printer is correctly connected. Also, ensure that the external printer is selected and online.
What to do if there's a light leak (Err07) in Hach 2100N Measuring Instruments?
If you are getting an Err07 error, it indicates a light leak. Make sure that the sample cell cover is closed properly. If the issue persists, use the I/O switch to turn the Hach Measuring Instruments off and then back on.
What to do if Hach Laboratory Equipment shows ERR11?
If the Hach Laboratory Equipment displays ERR11 on Hach Laboratory Equipment, which indicates a system loop test error, turn the instrument off and then back on.
