Installation and Start Up 2
Starting the Spectrophotometer
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.
