使用人员往往只注意选择仪表型号、分度相符并且精度高的仪表,却忽略了仪表的量程过大而引起的测量误差。本文就选择动圈仪表量程的方法做一介绍,以供参考. 动圈仪表的精度等级是由仪表的显示值、被测量的实际值及仪表的测量范围来决定的。 即: 式中:K——仪表精度等级; Fzs—
Users often only pay attention to select the instrument model, indexing and high precision instruments, but ignored the instrument caused by excessive measurement range error. This article on the choice of moving range measuring instrument method to do an introduction for reference.Automatic meter accuracy grade is displayed by the instrument value is measured the actual value and measuring range of the instrument to decide. Namely: Where: K-- instrument accuracy grade; Fzs-
