The Q-TESTER quartz watch core tester, which has been tested by the national watch quality supervision and inspection center, is a special detection instrument for quartz watch and watch core developed by the light industrial clock Research Institute. It can test the instantaneous diurnal difference, instantaneous monthly difference, average power current and quartz of the quartz watch and watch core of the pointer type and the digital display quartz watch. The parameters of crystal ppm and battery voltage are used to regulate the DC output voltage of 0.5 ~ 4.5V in digital way. The quartz clock tester can also provide a fast analog pulse signal for the stepping motor, which is suitable for all kinds of quartz watch production enterprises, maintenance units and personal use.
