Instrument Warm-up

Technically, once your spectrophotometer has passed the self-tests it is ready
to run samples. For best results you may want to let the spectrophotometer
warm up for at least 1 hour. This time allows the optical system to stabilize
and should result in better measurements. If the instrument was not stored at
room temperature before it was turned on, allow more time for the instrument
to stabilize.
In general, the life of your spectrophotometer will be increased by leaving it on
all the time but switching off the lamps when the instrument is not in use.
lamp intensity of the deuterium lamp and lifetime of lamps decrease with use.
