Protection class 2 (double or reinforced insulation, protective insulation)
CAT I
Measurement category I (overvoltage category) for measurements on
electrical and electronic devices that are not directly connected to the mains
(e.g. battery-operated devices, protective extra-low voltage, signal and
control voltages etc.).
CAT II
Measurement category II (overvoltage category) for measurements on
electrical and electronic devices that are directly connected to the 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 (overvoltage category) for measurements in
building installations (e.g. power outlets and sub-distribution units). 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 free contact length of 4 mm or with cover caps over the test
prods.
CAT IV
Measurement category IV (overvoltage category) for measurements at the
source of the low-voltage installation (e.g., main distribution board, house
transfer points of the energy provider etc.) and outdoors (e.g., earth cable
work, overhead line, etc.). This category also includes all smaller categories.
The measuring mode in CAT IV is only permissible with measuring tips
with a maximum free contact length of 4 mm or with covering caps on the
