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.
Caution Do not connect the NI 9476 with spring
terminal to signals or use for measurements within
Measurement Categories III or IV.
