三丰制作所以便于使用为目的,生产了一种不需要刻度与游标的读数卡尺.这种卡尺以毫米为单位计数,毫米以下可用刻度盘以0.02毫米为单位读数.以往的卡尺,需要依次读出主尺的刻度与游标刻度的数值,再将其折合计算;读数卡尺则不需要这些复杂的计算,它的读数部分较大,一看即可读出测量的数值. For ease of use, Mitutoyo has produced a reading caliper that does not require graduations and cursors. The calipers count in millimeters and can be read in 0.02 mm increments using dials. Previous calipers need to be read sequentially Out of the main scale and the cursor scale the value of the scale, and then converted into calculations; reading calipers do not need these complex calculations, the larger part of its readings, a look can read out the measured value.
