Analog Bus and Internal DMM Considerations

This section provides important environmental and electrical
considerations that can affect mainframe operation.

Environmental Operating Conditions

The 34980A mainframe, including the optional internal DMM, is designed
to operate in a temperature range of 0 °C to +55 °C with non- condensing
humidity. The maximum humidity is 80% at 40 °C or higher. Do not use in
locations where conductive dust or electrolytic salt dust may be present.
The 34980A should be operated in an indoor environment where
temperature and humidity are controlled. Condensation can pose a
potential shock hazard. Condensation can occur when the instrument is
moved from a cold to a warm environment, or if the temperature and/or
humidity of the environment changes quickly.
When used in pollution degree 1 conditions, the maximum voltage rating
for the Analog Buses is 300V. When used in pollution degree 2 conditions,
the maximum voltage rating is 100V. If conditions change, ensure that
condensation has evaporated and the instrument has thermally stabilized
until pollution degree 1 conditions are restored before turning on power to
the equipment.

Pollution Degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence (on insulation) (IEC
61010-1).
Pollution Degree 2: Normally only non-conductive pollution occurs.
Occasionally, a temporary conductivity (leakage current between isolated
conductors) caused by condensation can be expected (IEC 61010-1 ).
