1、Line Resistant Calibration: When measuring low resistant, the resistant of the test cables can impact results. Line resistant calibration removes remains resistant values, enhancing measurement accuracy. 2、499 Sets Data Storage, Reading: Displaying NULL when there are no stored data and FULL when storage is maxed, prompts user to manage stored data for subsequent test data saving. 3、Four Wire Test Method: Separating current and voltage electrodes eliminates internal wiring impedance and touch resistant, ensuring more accurate measurements. 4、High Accuracy Measurements: Achieve accurate measurements by minimizing errors in small resistant tests, ensuring accurate results. 5、USB Communicating Function: The instrument communicates with a PC via a Type C interface. Once the driver is installed on the PC, it can interact with the instrument, collect test results, and facilitate further data analysis. Sampling rate can be set on the PC software from 0.1S to 5S in 50ms increments.
