This section contains instructions on how to clean the sample chamber when a sample
is spilt, how to run the performance check to see if the instrument is operating normally,
and on replacing consumables.
Give consideration to the environment in which the instrument is to be operated. Keep
the instrument and surrounding area clean so that the spectrophotometer may be used
in a stabilized condition over a long period.
Note1: The operating procedure varies with the type of instrument. Operation is
described by instrument type. Read the portion relevant to your instrument.
Note2: It is recommended that the validation program (optional) is used for the
