Environmental Requirements
Set up the E4981A where the following environmental requirements are
satisfied.
Operating environment
Ensure that the operating environment meets the following requirements.

The environmental requirements listed above are NOT for the specifications
and measurement accuracy of the E4981A, but for its operating
environment.
Ventilation requirements
To ensure that the safety requirements, the specifications, and the
measurement accuracy of the Capacitance meter are met, you must maintain
the environmental temperature to within the specified range by providing an
appropriate cooling clearance around the Capacitance meter or, for the
rack-mounted type, by forcefully air-cooling inside the rack housing. For more
information on environmental temperatures that satisfy the specifications and
measurement accuracy of the Capacitance meter, see
and Supplemental Information," on page
The Capacitance meter conforms to the requirements of the safety
standard.When the environmental temperature around the Capacitance meter
is kept within the temperature range of the operating environment
specifications
The Capacitance meter still conforms to the requirements of the safety
standard it is installed with the following cooling clearance:
