All battery test equipment requires software to operate the instrument. The software interface can be one of the main differentiating points besides hardware performance. It is important to confirm the software communicates using a modern high-speed standard such as TCP/IP (Ethernet) protocol and whether high-performance microcontrollers are used internally. This helps future-proof the system as […]
阅读更多Accuracy represents the trueness of test equipment measurement; the closeness of average sample to its true value. Specifying this metric requires comparison to a known source such as a high-performance meter. Accuracy should not be confused with noise. The relationship between “accuracy” and “precision” relates to the measurement noise. As stated above, accuracy is how […]
阅读更多Robustness – the quality of materials and quality of construction have a major impact on how long the test equipment lasts and how long it will hold calibration. Resistance to corrosion and temperature fluctuations are significant attributes of high-quality test equipment. The instruments duty cycle and the maximum power rating also heavily contribute the usefulness and […]
阅读更多Temperature variance of the test equipment and the device under test will always affect the measurement. This is a physical property that cannot be escaped, but it can be minimized. Knowing how temperature affects the measurement empowers the researcher when determining the experimental error. When test equipment resolution and precision are sufficient, measurement fluctuation due […]
阅读更多Precision determines the level of noise/fluctuation present in the test equipment’s measurement. Precision also indicates the consistency and repeatability of the instrument’s measurement circuitry. A measurement with very little noise/fluctuation is considered to be precise. Measurement precision at “100ppm” indicates it will vary by no more than 0.01% (100/1,000,000). Many instruments will not specify their […]
阅读更多Resolution indicates the smallest change in measurement that can be detected by the instrument’s sense and control circuitry. Typically referred to in “bits” of resolution or an absolute unit of measurement such as µV or µA. For battery test equipment, resolution is determined by the analog to digital and digital to analog conversion, commonly known […]
