Maintenance
After Installing a New Lamp
Check the detector for noise and drift with the dry text cell installed in place of the sample
flowcell. Check the instrument's baseline for excessive noise or drift. Excessive noise and
drift after a lamp change may indicate that the lamp is improperly seated. Remove the lamp,
reinstall, and recheck. If any problems persist, call your PerkinElmer service engineer for
further assistance.
