 Installation (Overvoltage) Categories II (Mains Supply Connector)
& I (Measuring Terminals).
 Pollution Degree 2.
 Protection Class I.
PLEASE NOTE THE FOLLOWING:
 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. 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 an internal fan and
ventilation openings. Care must be taken to avoid restricting the airflow
around the apertures (fan holes) at the sides of the oscilloscope. Ensure
adequate ventilation by leaving the required 5 cm (2 inch) minimum gap
around the sides of the instrument.
CAUTION
Do not block the ventilation holes located on both sides of the
oscilloscope.
CAUTION
Do not allow any foreign matter to enter the oscilloscope through the
ventilation holes, etc.
