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 9683 to signals or use for measurements within

Measurement Categories II, III, or IV.

. This page contains the environmental regulations and

directives with which NI complies, as well as other environmental information not included in
this document.

1

Ensure that the local ambient temperature of the NI 9863 is -40 °C to 85 °C. Measure the local ambient
temperature by placing thermocouples on both sides of the PCB, 5 mm (0.2 in.) from the board surface.
