How to fix Shimadzu UV-2550 Measuring Instruments light source?
- KKevin LevyAug 8, 2025
If the light sources in your Shimadzu Measuring Instruments aren't lit, turn off the photometer unit and computer. Restart the startup procedure, watching to see if the lamps light up. If they don't, the lamps likely need replacement. The Wl lamp typically lasts for 2000 hours, and the deuterium lamp for 500 hours of operation. Replace the failed lamp and begin the startup procedure again.
