A.3.7 Faults And Abnormal Stresses; A.3.8 Definitions - AOIP CP6632 Mode D'emploi

Before changing function, disconnect the measuring wires from the external
circuit. Remember that when taking even low current and/or voltage
measurements, that the circuits can carry voltages which, with respect to
earth, are hazardous for the operator.
Never take measurements when the instrument is connected to another
appliance by the USB link or when charging the batteries (option)

A.3.7 Faults and abnormal stresses

Whenever the level of protection afforded by the instrument is suspected of
being impaired, remove it from service and ensure it cannot be put back into
service accidentally.
It can be feared that the protection might have been impaired if, for example:
The instrument displays visible damage.
The instrument is no longer capable of
measurements.
The instrument has been stored in unfavourable conditions.
The instrument has suffered severe stresses during transport.

A.3.8 Definitions

A.3.8.1 Definition of category and pollution level
CAT II 60V:
The notion of categories determines the maximum transient voltage that can
be applied to the measurement inputs (it is also called overvoltage category).
For the CP6632, the maximum permissible overvoltage is 60V (DC or AC)
POL 2:
The notion of pollution determines the isolation distance between the circuits.
Level 2 allows temporary conductivity caused by condensation.
