Support three-terminal test, five-terminal end-face test and Kelvin test line expansion. Allow both convenient testing and high-precision testing requirements.

The recording mode can be used for data statistics to dynamically obtain the Average, Maximum, Minimum and Number of records

The tolerance mode can be used for component sorting. The nominal value, tolerance limit, alarm, LED indicator and counter can be set, and the percentage deviation between the measured value of the main parameter and the nominal value can be calculated for qualified and unqualified Compare, display GO/NG discrimination results. Tolerance range: 1%~20% Test speed: 20 times/s(Fast),5 times(Med),2 times/s (Slow)
