Hello, after replacement of the tungsten lamp, the calibration fails at step 3. Does anybody know what this means? It would maybe already help if the user manual was available in total, as the section 5 with error messages is missing in the uploaded pdf file. Thanks a lot for your help.

I would like to send our Beckman Coulter DU-730 Spectrophotometer to get it overhauled. Cleaned and repaired, if needed. Do you have a sales office in Iceland?
