Note: Installation (overvoltage) category I refers to situations where equipment measurement
terminals are connected to the source circuit. In these terminals, precautions are done to limit the
transient voltage to a correspondingly low level.
Installation (overvoltage) category II refers to the local power distribution level which applies to
equipment connected to the AC line (AC power).
Degree of Pollution
The oscilloscopes may be operated in environments of Pollution Degree II.
Note: Degree of Pollution II refers to a working environment that is dry and non-conductive pollution
occurs. Occasional temporary conductivity caused by condensation is expected.
IP Rating
IP20 (as defined in IEC 60529).
Cooling Requirements
This instrument relies on forced air cooling with internal fans and ventilation openings. Care must be
taken to avoid restricting the airflow around the apertures (fan holes) on each side of the scope. To
ensure adequate ventilation it is required to leave a 15 cm (6 inch) minimum gap around the sides of
the instrument.
CAUTION: Do not block the ventilation holes located on both sides of the
scope.
CAUTION: Do not allow any foreign matter to enter the scope through the
ventilation holes, etc.
