displays two TEMP °C screens, three CONFIGURE screens, a METHODS menu, and a
DIAGNOSTICS menu.
Recommendation:
Review all of these screens when initially setting up the 2414
RI detector.
Note that it takes several hours for the optics bench to stabilize at a new temperature.
Do not make a run until the temperature stabilizes. Changing temperature causes
baseline drift and can necessitate LED reoptimization.
