本文介绍的限时器采用电子表芯作定时及显示元件,限时时间为1、2、3、5、10、20、30及50min共八挡。限时准确,平时电子表仍可作计时用。 从给出的原理图中看,本线路从电子表芯上共有6根引出线,通过S_3选择限时时间,S_2为倍率选择开关。一般五功能电子表的表芯上共有13根输出脚,从左往右数,在第①脚和第(13)脚上为公共输出端,其余均为数字笔划段的输出端。因两根公共输出端的相位不同,所以引出笔划段必须根据两个公共端与各笔划段之间的关系来引出,见附表。
This article describes the use of time-stop timer for electronic timepieces and display components, the time limit of 1,2,3,5,10,20,30 and 50min a total of eight blocks. Accurate and accurate, usually electronic watch can still be used for timing. From the given schematic view, this line from the electronic watch a total of 6 pinout, select the time limit by S_3, S_2 for the magnification selection switch. General five-function electronic watch movements on the watch a total of 13 output pin, from left to right in the first and first (13) feet on the public output, the rest are digital strokes section output. Due to the different phases of the two common outputs, the lead-out stroke segment must be drawn according to the relationship between the two common terminals and the stroke segments, see the attached table.
