Installation category (overvoltage category) defines the level of transient overvoltage which the instrument is designed
to withstand safely. It depends on the nature of the electricity supply and is overvoltage protection means. For example,
in Cat II which is the category used for instruments in installations supplied from a supply comparable to public mains
such a hospital and research laboratories and most industrial laboratories, the expected transient over voltage is 2500 V
for a 230 V supply and 1500 V for a 120 V supply.

Pollution degree describes the amount of conductive pollution present in the operating environment. Pollution degree 2
assumes that normally only non-conductive pollution such a dust occurs with the exception of occasional conductivity
caused by condensation.
