Note 9. Measurement Category II is for measurements performed on circuits directly connected to the
electrical distribu on system. This category refers to local-level electrical distribu on, such as that provided by
a standard wall outlet, for example 115 V for US or 230 V for Europe.
Cau on! Do not connect the device to signals or use for measurements within Measurement Categories
III or IV.
