Environmental Conditions

Environmental Conditions
Overvoltage Category
This product is intended to be powered by MAINS that comply to Overvoltage Category II, which is
typical of cord-and-plug connected equipment.
Pollution Degree
The 9000 Series oscilloscope may be operated in environments of Pollution Degree 2 (or Pollution
Degree 1).
Pollution Degree Definitions
Pollution Degree 1: No pollution or only dry, non-conductive pollution occurs. The pollution has no
influence. Example: A clean room or climate controlled office environment.
Pollution Degree 2. Normally only dry non-conductive pollution occurs. Occasionally a temporary
conductivity caused by condensation may occur. Example: General indoor environment.
Pollution Degree 3: Conductive pollution occurs, or dry, non-conductive pollution occurs which
becomes conductive due to condensation which is expected. Example: Sheltered outdoor environment.
Measurement Category
Measurement Category
The Keysight Infiniium 9000 Series oscilloscopes are not rated for Measurement Category II, III, or IV.
Measurement Category Definitions
Measurement Category II is for measurements performed on circuits directly connected to the low
voltage installation. Examples are measurements on household appliances, portable tools and similar
equipment.
Measurement Category III is for measurements performed in the building installation. Examples are
measurements on distribution boards, circuit-breakers, wiring, including cables, bus-bars, junction
boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other
equipment, for example, stationary motors with permanent connection to the fixed installation.
Measurement Category IV is for measurements performed at the source of the low-voltage installation.
Examples are electricity meters and measurements on primary overcurrent protection devices and ripple
control units.
Transient Withstand Capability
The maximum transient withstand capability of this instrument is not specified. Do not apply more than
5 volts rms at the oscilloscope's vertical input BNC connectors.
