Product Description

DC Low Resistance Digital Resistance Meter Component Tester

CN251X Series Intelligent DC Low Resistance Tester is an instrument for testing all kinds of DC resistance of transformers, motors, switches, relays, connectors and so on.
The instrument has the advantages of wide measuring range, high precision and fast speed. The instrument adopts high-precision constant current flow through the measured parts and five-end measurement effectively deducts the lead error, which is suitable for users to make high-precision measurements; at the same time, the instrument has increased the sorting function, and the user can directly set the upper and lower limit values of the resistance or the percentage error for sorting, which greatly improves the speed of the testing of the same kind of products.
