I. Product Overview 
 HDGC3986 intelligent charge and discharge tester set charge and discharge, monomer detection, monitoring and activation Observing body of a machine. Reduce the cost of doing business, reducing the labor intensity of the maintenance personnel, the maintenance of the batteries and the UPS power supply to provide a comprehensive scientific testing means. 
 The machine adopts the new power devices, patented technology, to achieve constant current discharge, intelligent three-stage charging, Equalize / Float, constant current / constant voltage automatic conversion; real-time online polling of each single battery or the whole set of batteries voltage, on-line detection, recording a single section or the whole battery voltage, and data stored or transmitted to a PC; large-screen LCD, full Chinese menu prompt, easy to operate, high degree of intelligence, can be set set and control the parameters of voltage, current, time, capacity, auto-complete the testing, monitoring of various parameters of the battery pack; automatically release / activation charge the battery to extend battery life. Charge / discharge is completed, the test data through the RS232 interface directly upload to a PC or on-site data is transferred to the U disk; put / charge collected data supporting the data processing software to analyze the remaining battery capacity to generate a variety of charts, analysis of battery performance to provide a scientific basis. 

 Second, the product features 
 ? LCD display, Chinese menu prompt, easy to operate, high degree of intelligence, can set the parameters of voltage, current, time, capacity, auto-complete the testing, monitoring of various parameters of the battery pack. 
 ? Real-time online monitoring capabilities: real-time online monitoring and displays all test data: current, battery voltage, cell voltage, time, capacity, data storage and transmission to a PC, display and print a variety of charts. 
 ? Put automatic charging function: Set the put / charging current, duration, high capacity and its voltage limit, low limit, can be recycled to the first discharge, the charging process. 
 ? Battery activation function: set to put the number of charge cycles, and activation of the battery pack. 
 ? Automatic stop function: when any one of the following conditions are met automatically stops play / charge: time to the capacity to single battery protection voltage to the battery protection voltage to. 
 ? Protection function: if the abnormal voltage happens automatically stop the charging or discharging. 
 ? Voltage, current display calibration correction: calibrate the battery pack voltage, current, and single cell voltage. 
 ? U disk data-storage functions: charge, discharge, and automatically put the charge or dump the data collected after the end of the battery activation, U-disk, U disk to put / charge collection data dump to the PC. After supporting the data processing software processing, display, print a variety of charts. To provide a scientific basis to distinguish the pros and cons of the entire group or single cells.
