The rm3548 is a high precision portable resistance meter capable of measuring resistance levels from microohms to megaohms and is intended primarily for use in testing and maintenance of large equipment for example measuring the winding and weld resistances in large motors.
Usb cable resistance meter.
If you are using a regular cable max length of 5 meters for 2 0 and max length of 3 meters for 3 0 3 1 with an active cable then the maximum length for usb 2 0 is 25 meters about 82 feet and the maximum recommended length for usb 3 0 3 1 is 15 meters about 49 feet.
Hioki dc resistance meters measure a broad range of resistance values at a high level of precision.
Better quality usb cables are much more robust.
It seems a bit more accurate then some of the cheaper usb multi meters in this price range.
Look again at the usb cable in the 2 5 to 3 5 ohm range y axis expansion near the end at 9 75 min.
