How to use the handheld battery internal resistance capacity analyzer

two. Product features 　　 1. It can realize the connection resistance test to determine the battery's connectivity. It is completely online and easy to use.　　2. Intelligent data processing. The instrument is an all-Chinese operation interface and analysis software, making it easier to use and convenient for maintenance personnel to analyze and process.　　3. The standard internal resistance test method is adopted, and the voltage line, current line and data acquisition line are separated to effectively reduce the error of contact resistance. 　　4. Fault alarm, and timely detection of battery operation failures. When the detected internal resistance and voltage exceed the set upper limit or lower than the lower limit, the instrument will give a sound and text alarm. 5. The instrument has good repeatability and stability, and the stability of repeated tests is within 3%; the test signal is a large signal above 42A DC to ensure test accuracy; the large signal test can effectively resist the ripple interference of the battery test environment; 　　 6. The measurement parameters have high precision, strong anti-interference, high reliability and good repeatability. The battery charging and discharging waveform and switching noise basically do not affect the accuracy of the internal resistance. 7. Complete the test of voltage, internal resistance and connection resistance at one time, which truly reflects the test of all the parameters of the complete battery pack; complete the test of key indicators at one time, effectively improve the test efficiency; 　　 8. Fast test speed, each unit test The time is less than 3 seconds, and it can store more than 10,000 test data.　　9. The analysis software can automatically generate various test reports and reports: voltage, resistance, estimated capacity bar graphs, as well as single battery change trend graphs, data tables, etc.　　 10. The analysis software can also tailor some functions according to the actual needs of the user.　　11, low power consumption, rechargeable battery power supply, the screen displays the power supply battery power, can work continuously for 6 hours.　　Main function　　1. It can measure the voltage, internal resistance, connection bar resistance and capacity of the single battery.　　2. It can be tested offline or online, and the two test methods do not affect the test results.　　3. It can automatically estimate the battery capacity, and can measure 2V, 6V, 12V and other specifications of batteries, with a range of 0-6000AH.　　4. It has alarm functions such as wiring error, abnormal battery, and battery failure.　　5, with automatic test, manual test, voltage test, retest and other test modes 　　6, can set 9 different battery parameter modes, convenient to test different types of batteries.　　7. With analysis software, it can communicate with PC, and can analyze test data, including: voltage, internal resistance, connection resistance, capacity data table, histogram and battery change trend graph.　　 8. The historical data can be saved and managed dynamically and hierarchically according to the computer room/site name, battery pack name, battery model, type, manufacturer and installation date, so as to compare and recall the historical data at any time.
