Pollution Degree 2 refers to an operating environment where
normally only dry non-conductive pollution occurs. Conductivity
caused by temporary condensation should be expected.
Protection Class 1 refers to 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.
Cooling
The 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 any side of the oscilloscope. For
sides and rear apertures, ensure adequate ventilation by leaving the
required 10 cm (4 inch) minimum gap around the sides and rear of the
instrument. For bottom apertures, the oscilloscope feet (up or down)
provide adequate clearance. Ensure at least the minimum feet clearance
is achieved as paper or light objects can be drawn to and obstruct the
opening(s).
CAUTION
Do not block oscilloscope ventilation holes. For models with bottom
apertures, always keep items like sheets of paper clear of the
oscilloscope bottom.
The instrument also has internal fan control circuitry that regulates the
fan speed based on the ambient temperature. This is performed
automatically after start-up with no manual intervention required.
CAUTION
Do not allow any foreign matter to enter the oscilloscope through the
ventilation holes, etc.
