Maintenance
Maintenance should be performed periodically to keep the E5250A in good
condition.

Performance Verification

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 . Tra ined service personnel
will perform the performance verification.

Cleaning

Before performing cleaning, turn off the instrument, and disconnect power cable
from the rear panel. Use a dry cloth to clean the external case parts.
To prevent electrical shock, do not perform cleaning when the instrument is turned
on, and do not use a wet cloth.
