Features of Portable DC Resistance Tester:

1. Handheld three-channel DC resistance tester, lightweight and powerful, easy to carry.

2. One-time connection concept, no need to reconnect and disconnect test leads

3. Built-in large capacity lithium battery, can work continuously for more than 10 hours under typical conditions (typical conditions refer to measured resistance less than 100mΩ, 2A current range, battery fully charged).

4. Simple and efficient test procedure, 5 test modes selectable, the instrument automatically measures the resistance of the selected high-voltage or low-voltage side winding, including high and low voltage three-phase winding measurement, or single winding measurement.

5. Automatically selects test current, maximum current up to 2A.

6. Effective reading up to 50000 counts, display range 0-49999,
