量表单独使用时的满刻度读数可以为15伏。
你能读出刻度盘上的读数吗？
用读数保持电路记录压力变化，较直接读取刻度值更加准确，可靠。
More precise and reliable recording is achieved by reading-keeping circuit compared with the original gauge-reading.
罗马人发明的一种漏壶则是让水从蓄水器滴入一圆筒，筒内有一浮子，在筒壁的刻度尺上指示读数。
The Romans invented a clepsydra consisting of a cylinder into which water dripped from a reservoir; a float provided readings against a scale on the cylinder wall.
因此要注意，当我们把刻度刻成欧姆读数时，这些刻度是从大到小的。
Note, therefore, that when we calibrate the scale to read in ohms, these calibrations go backward.
度盘上最小的刻度为最小读数。
This smallest division on the scale is called the least count.
加大的，直读刻度-孔径容易识读，以最接近0.001或者0.02mm刻度的读数为准。
Magnified, direct reading scale -permits easy reading of hole diameters to nearest 0.001 or 0.02mm.
两尺杆形成一个角重叠于被测角上，反映在刻度尺上的角度刻线读数就是被测角度。
The two ruler rods form an Angle which is overlapped on a measured Angle. The read number of the Angle reticle reflected onto the graduation ruler is a measured Angle.
