User manual

CAT I Measurement Category I: For measuring circuits of electrical and electronic equipment that is not directly

supplied with a mains voltage (e.g. battery-operated devices, protective extra-low voltage, signal and con-

trol voltages).

CAT II Measurement Category II: For measuring electrical and electronic devices that are directly supplied with a

mains voltage via a mains plug. This category also includes all lower categories (e.g. CAT I for measuring

signal and control voltages).

CAT III Measurement Category III: For measuring circuits of installations in buildings (e.g. electric sockets or sub-

distributions). This category also includes all lower categories (e.g. CAT II for measuring electrical devices).

Measuring in CAT III is only permitted with test prods with a maximum exposed contact length of 4 mm or

with cover caps over the test prods.

CAT IV Measurement Category IV: For measuring at the origin of a low-voltage installation (e.g. mains distribution,

electricity provider’s transfer points to homes) and outdoors (e.g. when conducting tasks on underground

cables or overhead lines). This category also includes all smaller categories. Measuring in CAT IV is only

permitted with test prods with a maximum exposed contact length of 4 mm or with cover caps over the test

prods.
