This section describes the procedure for stopping the instrument's vacuum system and up to turning the power OFF.
HINT: The vacuum status affects the instrument's sensitivity. With the exception of situations where the instrument is not used for a long time, the instrument's vacuum system should be kept on in order to maintain a high vacuum in everyday use.
