How to Use Equipment Specifications to Predict Measurement Uncertainty An Example Using Tunnels A, B and C Data System.

摘要

This report illustrates a methodology for predicting data system measurement uncertainty using equipment specifications. The example presented is based on the data acquisition systems being built for Tunnels ABC. For this example, the measurement uncertainty is predicted for both voltage and force balance measurements. The analysis identified several error sources that could potentially prevent the system from meeting the requirements. Mitigation measures were identified that would enable the proposed system to meet the requirements.
