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 supply and 1500V for a 120V
supply.
