极限点设置 Limit Point Setting

  通过设置压力表的极限点,将起始值和终止值设置为理想特性曲线上的对应点。尽管与起始设置或BFSL(最佳拟合直线)相比,此定义将导致与特性曲线的最大偏差,但它是用户最容易理解的方法。因此,使用数据表中给出的信息,说明错误是如何定义的很重要。在设置极限值期间,与特性曲线的最终值的 0.5% 偏差大约对应于与BFSL的 0.25% 偏差。

  原文:

  By setting the limit points of a pressure gauge, the start value and the end value are set to the corresponding points on the ideal characteristic curve. Although this definition will result in the largest deviation from the characteristic curve compared to the start setting or to the BFSL (best fit straight line), it is the method most easily understood by the user. With information given in datasheets it is therefore important to state how the error has been defined. A deviation of 0.5% from the end value of the characteristic curve during the setting of the limit values corresponds approximately to a deviation of 0.25% from the BFSL.
