I have the error message EEE on my Hach DR2000 Spectrophotometer?

How do I clear it?

A: This error occurs due to taking three readings in a row with the lid open.

To clear this follow these instructions:

Press Shift, then Configuration, then scroll through the menu (using the up arrow), until you see “reset warnings”, press the Enter key, it should now read “completed”, press the Method key, it should now return to the original programme.

The DR2000 is the old workhorse of the Hach Lange range this simple spectrophotometer is still utilised by a number of companies for their analysis of COD (Chemical Oxygen Demand). It has now been replaced by the DR2800 spectrophotometer for information on this new product click the link, for replacement reagents, spares or Service on your DR2000 just contact Camlab on 01954 233130
