a. 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.
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 that can
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 (IPX0) – IPX0 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.
B.4 Operational specifications
The following table lists the operational specifications for the detector. All operational
specifications are measured following a warm-up period of >40 minutes with ambient
temperature at 25 °C ±3 °C.
