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 (e.g., 115 V for U.S. or 230 V for Europe). Examples of Measurement Category II are measurements performed on
household appliances, portable tools, and similar products.
Caution Do not connect the NI 9203 to signals or use for measurements within Measurement Categories III or IV.
