, verified by a 5 s dielectric
withstand test
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.
