Warning:
This device was designed in accordance with EN 61010-1 installation
category CAT II 500 V and CAT III 300 V. This implies that certain
restrictions in use apply that are related to voltages and voltage peaks
which can occur within the environment of use. Refer to the table above.
This device is only suitable for measurements up to 500 V in CAT II
and up to 300 V in CAT III
8. Pollution Degree
IEC 61010-1 specifies different types of pollution environments, for which
different protective measures are necessary to ensure safety. Harsher
environments require more protection, and the protection against the
pollution which is to be found in a certain environment depends mainly on
the insulation and the enclosure properties. The pollution degree rating of
the DVM indicates in which environment the device may be used.
Pollution
No pollution or only dry, nonconductive pollution occurs. The
degree 1
pollution has no influence. (only to be found in hermetically
sealed enclosures)
Pollution
Only nonconductive pollution occurs. Occasionally, temporary
degree 2
conductivity caused by condensation is to be expected.(home
and office environments fall under this category)
Pollution
Conductive pollution occurs, or dry nonconductive pollution
degree 3
occurs that becomes conductive due to condensation that is
to be expected.
(industrial environments and environments exposed to
outside air - but not in contact with precipitation)
Pollution
The pollution generates persistent conductivity caused by
degree 4
conductive dust or by rain or snow. (exposed outdoor
environments and environments where high humidity levels
or high concentrations of fine particles occur)
Warning: This device was designed in accordance with EN 61010-1
pollution degree 2. This implies that certain restrictions in use apply that
are related to pollution which can occur within the environment of use. Refer
to the table above.
This device is only suitable for measurements in Pollution
degree class 2 environments.
