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 80000 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 80000 Series oscilloscope is intended to be used for measurements in Measurement Category
I.
Measurement Category Definitions
Measurement category I is for measurements performed on circuits not directly connected to
MAINS. Examples are measurements on circuits not derived from MAINS, and specially
protected (internal) MAINS derived circuits. In the latter case, transient stresses are variable;
for that reason, the transient withstand capability of the equipment is made known to the user.
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.
