温度 测试设备和被测设备的差异总是会影响测量结果。 这是一个无法回避的物理特性,但它 可以 尽量减少。
在确定实验误差时,了解温度对测量的影响使研究人员有能力。当测试设备的分辨率和精度足够高时,会看到由于温度造成的测量波动。 渐进式 温度变化将 逐渐 结果数据出现偏差[上图],而温度的突然变化会导致数据的跳跃,如图所示[下图]。 使用具有适当热控制机制的抗温度变化的测试设备和控制测试环境的温度是很重要的。
将此转化为测试结果...
Arbin将温度对仪器精度的影响定义为 ~0.000185% / 1°C, by using patented shunt designs and high-quality materials that are resistant to temperature fluctuations. Additionally, some of Arbin’s test equipment uses internal thermal control mechanisms that isolate sensitive components and tightly regulate the temperature using techniques developed during a multi-year investigation with partners Ford Motor Company and Sandia National Lab’s metrology department; regarded as one of the best in the world. This technology allows the test equipment to maintain incredibly high precision measurements.
