    The governing discipline in ensuring a damage-free shipment is to ensure that the possibility of handling shocks to the PPI is minimized and/or prevented during transit. Fluke accomplishes this task by cradling the PPI within two foam cradles that are encapsulated within a double-walled, corrugated box. The PPI is restrained and supported, but still has resilience.

  • Page 81: A Summary Of Specifications

    Appendix A Summary of Specifications Uncertainty Analysis To perform an Uncertainty Analysis on a measurement device, you must be able to identify all of the parameters that influence the measurement. You must be able to quantify the magnitude of the potential error source and combine these into an overall uncertainty statement.
  • Page 82 RUSKA 7050, 7050i & 7050LP Users Manual characteristics of their device. Some manufacturers identify that their stability specification is proportional with time. Therefore, if the calibration interval were reduced in half, the magnitude of the stability specification would also be halved. This can be a powerful tool when you are trying to improve the measurement performance of a standard.
  • Page 83 In this approach, it is important to define the level of confidence that all of the uncertainty components are defined. For instance, all of the uncertainty specifications that Fluke Calibration publishes are at the 2 sigma level which would be at a 95% confidence level. Some manufacturers may state their uncertainty at different confidence level and therefore, you would need to be able to convert from one to the other in order to compare the two devices.
