A National Watch Quality Inspection Instrument For Quartz Watch
Jun 26, 2018

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.

Main technical indicators:

A. time base: + 0.01 constant temperature crystal oscillator

B. precision: + 0.01s/d (second / day) + 1s/m (SEC / month)

C. range: -9.99s/d ~ +9.99s/d; -999s/m ~ +999s/m

D. measurement cycle: 2S, 10s, 20s, 60s

E. adjustable DC power supply: output voltage 0.5 ~ 4.5V,

The output current is less than 50mA and the output current is less than 0.05V

F. power consumption current range: 0 ~ +9.99 A (10 A A); 0 ~ +999 A (1mA file)

G. power supply: single phase AC 220V + 10%, 8W

H. outline size: long * width * high = 270mm * 205mm * 80mm

I. weight: 1.4 kg

J. usage environment: temperature 0~40 C; relative humidity 0 ~ 80%RH
