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.
Note
Do not connect the NI-9853 to signals or use for measurements
within Measurement Categories II, III, or IV.
1
The maximum voltage that can be applied or output between any port or V
SUP
terminal and a COM terminal without creating a safety hazard.
