Measuring categories according to DIN EN
61010-1.
CAT I or unstipulated: Approved for measure-
ments in circuits which are not directly connected
to the low voltage mains grid (e.g. batteries).
CAT II: Approved for measurements in circuits
which are directly connected, by a mains lead and
plug for instance, to the low voltage mains grid
(e.g. household or office appliance and lab equip-
ment).
CAT III: Approved for measurements in circuits
which are part of a building's wiring installation
(e.g. stationary consumers, distribution terminals,
appliances connected directly to the distribution
box).
CAT IV: Approved for measurements in circuits
which are directly connected to the source of the
low voltage mains (e.g. electricity meters, main
service feed, primary excess voltage protection).
