quartz watch tester GDS-5B

1. Overview
The new GDS-5B quartz watch tester is suitable for precisely testing all kinds of clock circuits with crystal oscillator working at 32.768KHz and 1Hz, for example: quartz clocks,electronic watt-hour meter,motherboard,temperature controller,timer,electronic weigher and electronic cash register with timer function. Its appearance is depicted as Figure.1.

GDS-5B quartz watch tester especially suits the fast testing of finished products or semi-finished products. GDS-5B’s RS232 interface can be used to connect GDS-5B and computer in order to gather testing results. Additionally, our GDS-B quartz watch tester has a tinny probe with it, which can suits the testing of bigger circuit boards.
GDS-5B has five stalls:
 ppm：part per million, accurate to 0.1ppm
 s/d：seconds/day, accurate to 0.01 seconds
 s/m：seconds/month, accurate to 0.1 seconds
 s/y：seconds/year
 F:32.768KHz frequency deviation
Compared with the same type of products from other companies, our GDS-5B has the following advantages:
 with a more sensitive sensor in it to receive weak signal;
 taking non-contact method;
 thinner shell making it more easy to use and more suitable for the pipeline;
 with advanced CPU and TCXO(Temperature Compensated Crystal Oscillator);
 with a 16-level signal strength indicator;
 with the function of alarming, and the user can set alarming range;
 easy setting procedure;
 accuracy is better than 0.2ppm;
 extra：RS232 to connect GDS-5B to a computer
