First, the function 
 (1) the test function 
 HDGC3915 The company developed the most advanced communication and discharge test methods to accurately measure the battery voltage across the internal resistance, and battery battery capacity and the state in order to determine the pros and cons. Customers can choose according to their key operation and an LCD touch the two modes of operation. It can be the battery into a set of measurements, can also be a single measurement. 
 (2) data management capabilities 
 Automatically store data, and playback of data, access dump. 
 (3) management functions 
 Powerful computer analysis software, the battery by group, according to station, sub-time, sub-manufacturers for data analysis and management. 

 Second, the design features 
 1, using the most advanced LCD touch operation, user-friendly operator interface, beautiful appearance, small size, light weight, easy to operate, you can quickly complete the field measurement. 
 2, storage capacity, the 5200 battery test data can be stored in the table, and equipped with a dedicated computer management software, data storage, compared with the state of a battery of different periods, the battery deterioration trend analysis, etc., in order to achieve can be predictable and timely repair or replace the battery, avoid power breakpoint fault. 
 (3) in the case of strong ripple interference, accurate online test battery voltage, internal resistance. 
 4 can be customized according to user needs update the instrumentation program.
