Hi,
I have a problem with my LKB Pharmacia / Biochrom Ultrospec II (4050) Spectrophotometer. The calibration procedure on power up performs apparently well (no error occurs). But I have a wavelenght-offset of approximately 40nm. A real value of 530nm is displayed as 490nm. If I deactivate the calibration on power up the measured values are close to the real values, but not exactly due the missing calibration.
Is here someone who knows more about this old device and could help me? The manufacturer can't help me, because the support for this product ist not longer available.
Or has someone a service manual or knows somebody who might have one?
Thanks and regards!
Karl
