Main Feature

The instrument is controlled by a high-speed single-chip microcomputer, with full Chinese character display, high degree of automation and easy operation.
The instrument adopts a large liquid crystal display, which displays all data on one screen.
The instrument adopts brand-new power supply technology, with stable output current, high output voltage, fast measurement speed and wide range.
You can input the length and cross-section of the grounding wire, automatically calculate the resistivity and judge whether it is qualified.
Enter the conductor temperature, and automatically perform temperature conversion.
The instrument comes with a clock and a perpetual calendar, which can save 20 sets of test data, which is convenient for customers to inquire at any time.
The instrument comes with a thermal printer, which can print test data in real time.
The desktop computer has the function of scanning the code, reading the sample number, and has the function of logging in for the test personnel.
The desktop computer has a network interface, connects to the cloud platform through the interface, is incorporated into the test management system, and communicates with the cloud platform at any time.
