  • Page 92: Offset Error

    5730A Operators Manual Offset Error Offset error can be measured directly by finding the Calibrator output that causes a meter reading of 0 V. This error is called an offset because it reflects a fixed error that is present in all meter output readings. For example, if a meter reads 0 V when -1.3 mV is applied, the meter has an offset error of +1.3 mV.

    The 5730A Calibrator makes use of internal check standards and measurement systems. As a result, it can be completely calibrated in place to full specifications with a small number of convenient, portable, environmentally-tolerant standards available from Fluke Calibration. This procedure is traceable to military standard requirements.

  • Page 189: Establish Traceability

    Infrequent verification is done in the traditional way, by comparing selected ac voltage outputs with an external dc voltage standard through an external ac/dc transfer standard. Fluke Calibration recommends this to be done every two years or as determined by the policy of your organization.
