PLEASE NOTE THE FOLLOWING:
Installation (Overvoltage) Category II
refers to local distribution level,
applicable to equipment connected to
the mains supply (AC power source).
Installation (Overvoltage) Category I
refers to signal level, applicable to
equipment measuring terminals
connected to source circuits where
measures are taken to limit transient
voltages to an appropriately lower 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 grounded
equipment, where protection against
electric shock is handled by Basic
Insulation and by means of a
connection to the protective ground
conductor in the building wiring.
Cooling Requirements
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) at
the sides and front of the oscilloscope.
Ensure adequate ventilation by leaving a
required 15 cm (6 inch) minimum gap
around the sides, front, and rear of the
instrument.

ANUAL
Do not connect or disconnect probes or
test leads while they are connected to a
voltage source.
CAUTION
CAUTION
Do not block the ventilation holes
located on both sides and rear of the
DSO.
CAUTION
Do not allow any foreign matter to
enter the DSO through the ventilation
holes, etc.
