Operate the product at or below the measurement category1 marked on the hardware label.

Measurement circuits are subjected to working voltages2 and transient stresses (overvoltage)

from the circuit to which they are connected during measurement or test. Measurement

categories establish standard impulse to withstand voltage levels that commonly occur in

electrical distribution systems. The following is a description of measurement categories:

• Measurement Category I is for measurements performed on circuits not directly

connected to the electrical distribution system referred to as MAINS3 voltage. This

category is for measurements of voltages from specially protected secondary circuits.

Such voltage measurements include signal levels, special hardware, limited-energy parts

of hardware, circuits powered by regulated low-voltage sources, and electronics.

• Measurement Category II is for measurements performed on circuits directly connected

to the electrical distribution system (MAINS3). This category refers to local-level

electrical distribution, such as that provided by a standard wall outlet (for example, 115

AC voltage for U.S. or 230 AC voltage for Europe). Examples of Measurement Category

II are measurements performed on household appliances, portable tools, and similar

hardware.

• Measurement Category III is for measurements performed in the building installation at

the distribution level. This category refers to measurements on hard-wired hardware such

as hardware in fixed installations, distribution boards, and circuit breakers. Other

1Measurement categories, also referred to as overvoltage or installation categories, are defined in

electrical safety standard IEC 61010-1 and IEC 60664-1.

2Working voltage is the highest rms value of an AC or DC voltage that can occur across any

particular insulation.

3MAINS is defined as a hazardous live electrical supply system that powers hardware. Suitably

rated measuring circuits may be connected to the MAINS for measuring purposes.

4| ni.com | PXIe-6674T User Manual

examples are wiring, including cables, bus bars, junction boxes, switches, socket outlets

in the fixed installation, and stationary motors with permanent connections to fixed

installations.

• Measurement Category IV is for measurements performed at the primary electrical

supply installation typically outside buildings. Examples include electricity meters and

measurements on primary overcurrent protection devices and on ripple control units.
