Why do I get "Err 1" reading on my turbidity meter?
"Err 1" is an error code that signifies that the light flow is reduced. The cuvet should be cleaned with the solution and the tissue designed for this use. If this procedure has not removed your error code, the light source will need cleaning. This should be performed yearly, more frequently if required. The light source inside the cavity should be cleaned with the aid of a cotton swab dipped in alcohol.
