Measurement Risk and TUR Calculator Tool

Decision Rules can be difficult to understand, and this worksheet will help simplify things by focusing on measurement risk. It will help cure those measurement headaches allowing anyone to calculate TUR properly, and Measurement Risk Correctly. Use this tool to input parameters such as accuracy requirement, resolution, measurement uncertainty, and repeatability with other error sources. The tool will calculate how good the reference standard uncertainty needs to be to maintain test uncertainty (TUR) ratios and will allow the end-user to input their own risk tolerances.

Probability of False Accept (PFA) Worksheet

Decision Rules can be difficult to understand, but this worksheet will help. Use this tool to input parameters such as accuracy requirement, resolution, measurement uncertainty, and repeatability with other error sources. It will help make decisions on equipment, such as: Should I buy a device with better resolution? Do I need my calibration provider to have better measurement uncertainty than what I am getting? It also provides different Methods, using different decision rules (Method 5 and 6). The PFA calculator contains macros.
