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:

u ppm：part per million, accurate to 0.1ppm

u s/d：seconds/day, accurate to 0.01 seconds

u s/m：seconds/month, accurate to 0.1 seconds

u s/y：seconds/year

u F: 32.768KHz frequency deviation

Compared with the same type of products from other companies, our GDS-5B has the following advantages:

u with a more sensitive sensor in it to receive weak signal;

u taking non-contact method;

u thinner shell making it more easy to use and more suitable for the pipeline;

u with advanced CPU and TCXO(Temperature Compensated Crystal Oscillator);

u with a 16-level signal strength indicator;

u with the function of alarming, and the user can set alarming range;

u easy setting procedure;

u accuracy is better than 0.2ppm;

u extra：RS232 to connect GDS-5B to a computer
