Performance verification must be performed periodically so that the instruments
satisfy the specifications, and keep a good condition. It is recommended to perform
the performance verification once a year at least. For the performance verification,
contact your nearest Agilent Technologies Service Center. Trained service personnel
will perform the performance verification.
Cleaning
Before performing cleaning, turn off the instrument, and disconnect power cable
