I have acquired Beckman DU-650 Sprectrophotometer which seemes to be working properly except that the reported wavelength is off by approx 6 nm. The built in wavelength calibrate just errors out. Is there a way to reset something so that an offset number can be applied? Would the repair manual (which I don't have) cover this?
Thanks!
