  1. As a ratio device, the accuracy specifications can be improved upon based on your standards and environmental conditions.
  2. Ratio bridge where the ratio accuracies can be verified at anytime using the interchange technique method for 1:1 ratio measurements with the following equation re=(Ra-1/Rb)/2
  3. Uncertainties follow GUM at 2 sigma level (95%) along with degrees of freedom
