Handling and Storage
— Use the plastic end caps and store the calibration devices in the foam-lined 
storage case when not in use.
— Never store connectors loose in a box, in a desk, or in a bench drawer. This 
is the most common cause of connector damage during storage. Keysight 
recommends that you purchase the optional ECal Storage Box (not 
included with an ECal kit). Refer to “ECal Kit Storage Box (Option 150) – 
(N755xA Only)” on page 4-23. This is a container for securing your ECal 
module and accessories, such as a USB cable, wrenches, and adapters. For 
ordering information, see “Other ECal Accessories” on page 6-10.
— Keep connectors clean.
— Do not touch mating plane surfaces. Natural skin oils and microscopic 
particles of dirt are easily transferred to a connector interface and are very 
difficult to remove.
— Do not set connectors contact-end down on a hard surface. The plating and 
the mating plane surfaces can be damaged if the interface comes in 
contact with any hard surface.
