常用的指针式仪表,采用固定式单标尺,一台仪表只对应一被测参数的某一测量范围,当被测参数的测量范围变更时,需要更换规格不同的仪表。为解决这一矛盾,我们将仪表的固定标尺改制成活动式标尺,其形式:可采用滚动式标度简(图1),旋转式标度盘(图2)或胶转式标度带(图3)。活动式标尺上有数条标度尺,当测量范围变更时,活动标尺就滚动或旋转一档,使之与测量范围相对应。这样就无须变更仪表,用一台仪表替代了原来多台仪表的功能。

Commonly used pointer instrument, using a fixed single scale, a meter corresponds to a measurement of a measured parameter range, when the measurement range of the measured parameters change, you need to replace the different specifications of the instrument. In order to solve this contradiction, we converted the fixed scale of the instrument into a movable scale. The form of the scale can be rolling scale (Fig. 1), rotary dial (Fig. 2) or glue rotary scale image 3). There are several scales on the movable ruler. When the measuring range is changed, the movable ruler scrolls or rotates a file to make it correspond to the measuring range. In this way there is no need to change the meter, with a meter instead of the original multi-meter function.
