I have a customer with a Pharmacia Biotech UV/Vis Spec

Ultrospec 2000 Model 80-2106-09

After power up calibration it gives an error: Abs non-linear!

Then it prints a report with "GLP calibration FAIL"

They replace the lamps, problem stayed the same.

I cleaned the filters and mirror, the energy significantly increased but the problem stayed.

This product line is now sold by GE Medical. They have obsoleted the unit and will offer no support.

Any thoughts?
