NI 951x User Manual

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.

Caution

Do not connect the NI 951x to signals or use for measurements within

Measurement Categories II, III, or IV.
