fully understood and met.
CAT I
Installation (Overvoltage) Category rating per EN 61010-1
safety standard and is applicable for the oscilloscope front
panel measuring terminals. CAT I rated terminals must only
be connected to source circuits in which measures are taken
to limit transient voltages to an appropriately low level.
Operating Environment
The instrument is intended for indoor use and should be operated in a
clean, dry environment with an ambient temperature within the range of +10
°C to 40 °C.
Note: Direct sunlight, radiators, and other heat sources should be taken
into account when assessing the ambient temperature.
WARNING
The oscilloscope must not be operated in explosive, dusty, or wet
atmospheres.
CAUTION
Do not exceed the maximum specified front panel terminal (CH1, CH2, EXT
TRIG) voltage levels. Refer to Specifications for more details.
Installation (Overvoltage) Category II refers to local distribution level, which
is applicable to equipment connected to the mains supply (AC power
source).
Installation (Overvoltage) Category I refers to signal level, which is
applicable to equipment measuring terminals that are connected to source
circuits in which measures are taken to limit transient voltages to an
appropriately low level.
Pollution Degree 2 refers to an operating environment where normally only
dry non-conductive pollution occurs. Occasionally a temporary conductivity
caused by condensation must be expected.
Protection Class 1 refers to a grounded equipment, in which protection
against electric shock is achieved by Basic Insulation and by means of a
connection to the protective ground conductor in the building wiring.
