There are a number of tests in the Hach LCK cuvette range that require a blank vial to be tested prior to running a sample. The value E1 on screen indicates that this value is to be subtracted from the final reading. This will also appear with some tests where the value is measured before and after the sample addition.

The hach DR2800 spectrophotometer has been discontinued and replaced by the DR3900 benchtop spectrophotometer and the DR1900 portable spectrophotometer.
