Set up the E4990A where the following environmental
requirements are met.
Ensure that the operating environment meets the following
requirements.

Above environmental requirements are NOT for the specifications and
measurement accuracy of the analyzer, but for the operating environment of
the analyzer.
To ensure safety requirements, the specifications and
measurement accuracy of the analyzer, you must keep the
environmental temperature within the specified range by
providing appropriate cooling clearance around the analyzer
or, for the rack mount type, by forcefully air- cooling inside
the rack housing. For more information on environmental
temperature to satisfy the specifications and measurement
accuracy of the analyzer, see the specification in the E4990A
Datasheet.
When the environmental temperature around the analyzer is
kept within the temperature range of the operating
environment specification (See Section
Environments" on page
requirements of the safety standard. Furthermore, under
that temperature requirement, the analyzer still conforms to
the requirements of the safety standard even when placing
the analyzer with cooling clearance as follows:
5 °C to 40 °C
23 °C ± 5 °C (< 1 °C deviation from the temperature
when performing the error-correction)
20% to 80% at wet bulb temperature < +29 °C
