Protection class
a
a. Protection Class I
–
The insulating scheme used in the instrument to protect you from electrical
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 connected to a
grounding system. In turn, this grounding system is connected to the third pin (ground pin) on the
electrical power cord plug.
Class I
Overvoltage category
b
b. Overvoltage Category II
–
Pertains to instruments that receive their electrical power from a local
level such as an electrical wall outlet.
Category II
Pollution degree
c
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 to normally only nonconductive
pollution. Occasionally, however, a temporary conductivity caused by condensation must be
expected.
Degree 2
Moisture protection
d
d. Moisture Protection – Normal (IPXO) – IPXO means that there is no Ingress Protection against
any type of dripping or sprayed water. The X is a placeholder to identify protection against dust, if
applicable.
