1. Overview

 The new QWA*5A quartz watch tester is suitable for precisely testing all kinds of quartz watch circuits with crystal oscillator working at *2.**8KHz, for example: quartz quartz watchs,electronic watt-hour meter,computer motherboard,temperature controller,timer,electronic weigher and electronic cash register with timer function. Its appearance is depicted as Figure.1.

Figure.1  QWA*5A quartz watch tester
QWA*5A quartz watch tester especially suits the fast testing of finished products or semi-finished products. Additionally, our QWA*5A quartz watch tester has a tinny probe with it, which can suits the testing of bigger circuit boards.
QWA*5A has three stalls:

1. ppm：part per million
2. s/d：seconds/day
3. s/m：seconds/month

Compared with the same type of products from other companies, our QWA*5A has the following advantages:

1. with a more sensitive sensor in it;
2. taking non-contact method;
3. with advanced CPU and TCXO(Temperature Compensated Crystal Oscillator);
4. with the function of alarming, and the user can set alarming range;
5. easy setting procedure;
6. accuracy is better than 0.3ppm;
7. parameters that was set once wont be lost when starting again
