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