_________________________________________
1 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 its 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 as hospital and research laboratories and most
industrial laboratories, the expected transient overvoltage is 2500V for a 230V sup-
ply and 1500V for a 120V supply.
2 Pollution Degree describes the amount of conductive pollution present in the operat-
ing environment. Pollution Degree 2 assumes that normally only non-conductive
pollution such as dust occurs with the exception of occasional conductivity caused by
condensation.
