Attribute Specification
Protection class
1
1. Protection Class I – The insulating scheme used in the instrument to protect 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
2
2. Overvoltage Category II
–
Pertains to instruments that receive their electrical power from a local level
such as an electrical wall outlet.
II
Pollution degree
3
3. 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.

Moisture protection
4
4. 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 identifies protection against dust, if
applicable.
