Microcontroller based Digital Micro-Ohm Meter Model LR-1A (1A DC test current) manufactured by Neutronics Manufacturing Company is ideally suited for measuring very low resistance down to 1μ2. Use of four wire system eliminates lead resistance errors. The LR-1A has LCD display with resistance measurement range from 10 to 3ΚΩ with minimum resolution of 1μ2. This mains-operated meter is very rugged, portable and light weight. The LR-1A is suitable for measuring resistances of Low voltage cables, wires, conductors, motor winding resistance, wirewound resistance, toggle switches & micro switches, transformer winding resistance of small transformers & other low resistance materials.
