Calibrate Perkin Elmer UV/VIS Lambda 900
Wavelength calibration

run program c:\uvwinlab\service9.exe

The spectrometer needs to be switched on for at least an hour (indicated in the program).
Also make sure the white light is visible on moving the wavelength to 0 nm. Otherwise make a scan from 2000 → 400 nm. This usually solves it.

It calibrates :

• Slit
• UV/VIS 2 peaks (using the 656.1 nm from the internal deuterium lamp, and it's zero order)
• NIR 2 peaks (using the 2nd order of the 656.1 nm)
• 0% Transmission

This takes about 10-15 minutes, after which “Calibrated successfully” is displayed.
