What is the basic function of the battery internal resistance meter?

Battery internal resistance tester is also called battery internal resistance tester.

The main functions are as follows:

1. Keyboard setting: Users can set discharge current, protection voltage, discharge capacity, discharge duration and other parameters according to battery capacity or detection requirements.

2. Real-time monitoring function: display the set parameters (such as voltage, current, time, etc. ）。

3. Perfect automatic protection function and alarm function: The unloader has the automatic protection function of undervoltage, high temperature, reverse connection and power failure, and can give an alarm sound.

4. record query:? The discharge device can store 8 times of discharge data (each time 10 hour), and users can inquire according to their needs.

5. Real-time communication: It can communicate directly with PC through RS232 interface to realize computer monitoring, data analysis and processing.

6. Calibration and correction function of voltage and current display values: it mainly calibrates the total voltage and current of the battery pack.

7. Data transmission and processing function: After discharging, the data is transmitted to the computer through USB flash drive or RS232 interface, and various charts can be automatically generated after background processing, which provides scientific basis for judging the quality of the battery pack.

8. Computer control function: the computer can obtain the state information of the unloader at any time and control the unloader to start, stop or suspend unloading; The discharge parameters of the discharge instrument can be set and modified; Select the discharge mode of the discharge instrument, etc.

9. The discharger has power-off memory function. All test data will not be lost after power failure, and discharge can continue without resetting parameters after power failure.
