| Abstract: | At first, this thesis states the importance of evaluating on the uncertainty of measurement for measuring system. By means of evaluating & dynamic analyzing on the resistance measuring with HIOKI3280-10 CLAMP ON HITESTER, I adduced & made use of the GM modeling (1,1) on the measuring system's dynamic forecasting, and I found the dynamic modeling on the uncertainty of measurement. Afterwards, I tested & verified the forecasting accuracy. The results indicated that the modeling can fairly accurate forecast the variation tendency of the uncertainty of measurement for this measuring system. In order to assure the quality of measuring results continuously, I put forward some advices and verdicts at last. |
