NI USB-6008/6009 User Guide and Specifications
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). 
Examples of Measurement Category II are measurements performed 
on household appliances, portable tools, and similar E Series devices. 
Measurement Category III is for measurements performed in the 
building installation at the distribution level. This category refers to 
measurements on hard-wired equipment such as equipment in fixed 
installations, distribution boards, and circuit breakers. Other examples 
are wiring, including cables, bus-bars, junction boxes, switches, 
socket-outlets in the fixed installation, and stationary motors with 
permanent connections to fixed installations. 
Measurement Category IV is for measurements performed at the 
primary electrical supply installation (<1,000 V). Examples include 
electricity meters and measurements on primary overcurrent 
protection devices and on ripple control units.
