Measurement Category II is for measurements performed on

circuits directly connected to the electrical distribution system.

This category refers to local-level electrical distribution, such as

that provided by a standard wall outlet (for example, 115 V for U.S.

or 230 V for Europe). Do not connect to signals or use for

measurements within Measurement Categories III or IV.
