Motwane’s Digital Micro Ohmmeter- LR-2045 is capable of measuring very low resistances (as low as 0.1 μΩ) in micro ohms. This easy to use ohm meter has a 4½ digits LED display. LR-2045 intends to replace the Kelvin bridge and old technology micro ohmmeters to increase productivity, thus saving time. It works on the proven principle of the four wire measurements. The resistance measurement range of LR-2045 is from 2mΩ to 2kΩ with a minimum resolution of 0.1μΩ. The maximum DC current injection is 1A. The pulse mode operation is an additional feature along with the PC interface. The LR-2045 can be used for measuring the resistance of cables, PCB, Relay, LT bus bars, low capacity motors, welded joints, etc.
