Measurement Category II
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 use
this module with Measurement Category III or IV voltages.

Measurement Category I
Measurement Category I is for measurements performed on circuits not
directly connected to the electrical distribution system referred to as
MAINS
voltage. MAINS is a hazardous live electrical supply system that
powers equipment. This category is for measurements of voltages from
specially protected secondary circuits. Such voltage measurements include
signal levels, special equipment, limited-energy parts of equipment,
circuits powered by regulated low-voltage sources, and electronics. Do not
use this module with Measurement Category II, III, or IV voltages.
