1.1 Purpose

Intelligent battery internal resistance testerBy adopting the most advanced AC discharge testing method, it is possible to accurately measure the voltage and internal resistance at both ends of the battery, and use this to determine the quality of the battery capacity and technical status. Customers can choose the internal resistance test of the battery according to their own situation、voltage testreachCapacity estimationThe result ofAs the basis for internal resistance matching when assembling new batteries; Testing the internal resistance of the battery before and after discharge is used to identify truly outdated batteries.

1.2 Characteristics

lIntelligent and digital, fully Chinese operation menu, accurate measurement, and simple operation.

lWeight not exceeding0.45KgHandheld design, single person operation, automatic measurement throughout the process.

lTo meet various battery internal resistance detection standards, a complete database of battery internal resistance parameters must be included, and the battery standard internal resistance can be defined according to different batteries.

lThe testing method is simple, will not affect the working state of the battery, and will not pose any safety hazards.

lThe instrument itself can store a large amount of test data and perform conclusive queries and analysis on the instrument. It can also use battery test data forUExport the disk to computer software to generate charts and curves for analysis.

lTest reports can be easily importedExcelandWordFile and print it as a report in the specified format for easy management and to reduce workload.

lFour terminal multi-purpose testing clip, integrating testing clip, probe and other functions, capable of adapting to98%The above battery connection installation methods and battery pole forms.

Instrument startup/Shutdown

There is one on the left side of the instrument panelTurn the power switch to the upper end to turn it on, and turn it to the lower end to turn it off.Main startup interface:

The entire interface consists of three parts: top, middle, and bottom. On the upper left is the menu name, and on the right is the battery level display bar. The bottom edge is the time bar, and the middle is the display and operation area；

When using touch screen operation, you can directly click on the menu task item, and then click on the selected menu task item to execute it. If using keyboard operation, use“TAB”Press the key to switch the selected menu task item, and press confirm to execute.

2.2.1Customize standard parameters

clickThe "Unit" button on the right side of "Battery Voltage" will pop up a custom parameter dialog box. After setting the custom parameters, click "Save". After saving, you can see the button“V”Become 'customized'x”, indicating successful customization.

2.2.2Standard parameter selection

clickThe button on the right side of the "Battery Voltage" or "Standard Capacity" characters can pop up a list of standard parameters. Select a parameter according to your needs, click again to set the parameter, and the main interface will update and display. After clicking the "Save" button at the bottom of the "Group Measurement" interface,

The set parameters will be permanently saved, and will not be lost when turned on or off again. There is no need to set the parameters again, making it convenient for the next test.
