GDS-5B CLOCK TESTER USER MANUAL SHEN ZHEN WISDOM SOURCE ELECTRONICS CO LTD [ADRESS：Mingzhi Street, Baoan District, ShenZhen, China] 1. Overview The new GDS-5B clock 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. Figure.1 GDS-5B clock tester GDS-5B clock 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 clock 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 0.03s/d;  extra ：RS232 to connect GDS-5B to a computer 2.
