对于物理实验所需的测量仪器有些刻度是均匀的,有些刻度是不均匀的,其原因是刻度对应的物理量与被测量是否成线性关系.下面从测量原理和公式的角度解析指针式多用电表、密度计以及自制电子秤等3种典型测量仪器刻度是否均匀的原因.1指针式多用电表的刻度是否均匀 Some of the measuring instruments required for physical experiments are uniform, some of the graduation is not uniform, the reason is that the physical volume corresponding to the scale and the measured whether a linear relationship between the following principles and formulas from the perspective of measurement pointer multimeter, Density meter and home-made electronic scales and other 3 kinds of typical measuring instruments are uniform scale 1 pointer multimeter scale is uniform
