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 the NI USB-9162 to signals or use for measurements within Measurement
Categories III or IV.
