Introduction
With new materials and material applications come new test challenges. As these new challenges emerge in materials testing, novel test protocols are required for evaluating the performance and predicting the failure of these new materials. Accuracy, precision, and control are all key elements of a test instrument that enable researchers to develop unique test protocols and evaluate the performance of their materials. In this article the three key elements of the Keysight Technologies, Inc. Nano Indenter G200 are evaluated.
The accuracy and precision of the nanoindenter system were evaluated using a calibrated reference material. Given that the system is calibrated correctly, which can be determined by assessing the accuracy, two primary sources of error affect the precision of the instrument: displacement noise and thermal drift. Both of these sources of error were evaluated.
