a. Protection Class I – The insulating scheme used in the instrument to protect from elec-
trical shock. Class I identifies a single level of insulation between live parts (wires) and
exposed conductive parts (metal panels), in which the exposed conductive parts are con-
nected to a grounding system. In turn, this grounding system is connected to the third pin
(ground pin) on the electrical power cord plug.
b. Overvoltage Category II
– Pertains to instruments that receive their electrical power
from a local level such as an electrical wall outlet.
c. Pollution Degree 2
– A measure of pollution on electrical circuits, which may produce a
reduction of dielectric strength or surface resistivity. Degree 2 refers only to normally
nonconductive pollution. Occasionally, however, expect a temporary conductivity caused
by condensation.
d. Moisture Protection – Normal (IPXO) – IPXO means that no Ingress Protection
against any type of dripping or sprayed water exists. The X is a placeholder that identi-
fies protection against dust, if applicable.
