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.
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 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.
How to fix Err01 error on Hach Measuring Instruments?
The Err01 error appears when the dilution water is calculated to be greater than 0.5 NTU. To resolve this, start the calibration again using higher quality dilution water. Alternatively, filter the water with a membrane filter before use.
