WJ-A-GS-E Rev A 9
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.
The instrument is intended for indoor use
and should be operated in a clean, dry
environment.
Note: Direct sunlight, radiators, and other
heat sources should be taken into account
when assessing the ambient temperature.
WARNING
The scope must not be operated in
explosive, dusty, or wet/damp
atmospheres.
The design of the instrument has been
verified to conform to EN 61010-1 safety
standard per the following limits:
Installation (Overvoltage) Categories II
(Mains Supply Connector) & I (Measuring
Terminals)
Pollution Degree 2
Protection Class I
Note:
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
CAUTION
Protect the scope’s display touch
screen from excessive impacts with
foreign objects.
CAUTION
Do not exceed the maximum specified
front panel terminal (CH1, CH2, CH3,
CH4, EXT) voltage levels. Refer to
Specifications for more details.
CAUTION
Do not connect or disconnect probes or
test leads while they are connected to a
voltage source.
