Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical—describes the performance met by a majority of models.
  • Nominal—describes an attribute that is based on design, conformance testing, or supplemental testing.

    • Specifications are Typical unless otherwise noted.

    Conditions

    Specifications are valid under the following conditions unless otherwise noted.

    • 0 °C to 55 °C
    Notice The terminals or pins of this device are not protected from electromagnetic interference. As a result, this device may experience reduced measurement accuracy or other temporary performance degradation when connected cables are routed in an environment with radiated or conducted radio frequency electromagnetic interference.
