Measurement class definition
⚫
Class I
refers to measurements taken on a circuit not directly connected to
the main power supply. For example, measurements made on circuits that
are not exported from a main power supply, especially from a protected
(internal) main power supply. In the latter case, the instantaneous stress will
change. Therefore, the user should understand the instantaneous capacity of
the instrument.
