WaveMaster 8 Zi – Zi-A Oscilloscopes
 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) at the sides, rear, and bottom 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 as paper or light objects can be drawn
to and obstruct the opening.
CAUTION
Do not block the ventilation holes located on both sides and rear of the
oscilloscope. For 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.
