Category I overvoltage conditions.
Measurement instruments whose measurement inputs are
not intended to be connected to the mains supply. The
voltages in the environment are typically derived from a
limited-energy transformer or a battery.
Category II overvoltage conditions.
Measurement instruments whose measurement inputs are
meant to be connected to the mains supply at a standard wall
outlet or similar sources.
Category III overvoltage conditions.
Measurement instruments whose measurement inputs are
meant to be connected to the mains installation of a building.
