1. The voltage measurement range of the battery internal resistance tester is 100V and 400V respectively, and the resistance test range is 0.0001mΩ~3.2kΩ. The 4.3-inch large-screen LCD display can display the battery internal resistance and voltage at the same time. The instrument has high-precision, high-resolution and ultra-high-speed measurement characteristics, providing 0.5% resistance accuracy and 0.01% voltage accuracy, and the maximum measurement speed can reach 65 times/second. At the same time, it is equipped with general data acquisition software as standard, which can read the test data into the computer and record it in ordinary spreadsheet software and CSV files. It is suitable for time interval measurement and manual measurement using trigger keys and external triggers, and can be effectively used in remote control and data acquisition and analysis. It can be used for professional sorting, and the resistance and voltage are independently compared. HI/IN/LO judgment can be performed. The judgment results can be displayed on the screen, beeped, and external I/O output. It can automatically determine whether the battery parameters meet the standards, and calculate the pass rate. It is suitable for the detection and sorting of various batteries. The instrument uses an enhanced computer remote control instruction set, is compatible with SCPI, and can efficiently complete remote control and data acquisition functions.

2. Resistance test range: 0.0001mΩ~3.2000kΩ;

Voltage test range: 0.00001V~404.000 VDC.

3. The instrument can realize automatic range and manual range test.

Manual range: 3mΩ, 30mΩ, 300mΩ, 3Ω, 30Ω, 300Ω, 3kΩ

4. Equipped with RS-232C and USB Device interfaces, the instrument is equipped with general data acquisition software, built-in database function and Excel export function, which can be effectively used for remote control and data acquisition and analysis. Standard Handler (PLC) interface: separate output resistance HIGH/IN/LOW signal and voltage HIGH/IN/LOW signal, which can fully cope with high-speed automatic sorting system to complete fully automatic assembly line test, and the enhanced IO signal can directly drive power relays and signal relays.
