Motwane LR 2065

Motwane’s Digital Micro Ohmmeter, LR -2065, comes with a maximum 10A DC current injection which is useful for the measurement of very low resistances (as low as 0.1 μΩ) in micro ohms. Mains cum rechargeable battery operated LR-2065, works on the proven principle of four wire measurements. The LR-2065 has 4½ digits LED display with a resistance measurement range from 2mΩ to 20KΩ, with a minimum resolution of 0.1μΩ. The pulse mode operation is an additional feature. The LR-2065 can be used for measuring the resistance of cables, wires, PCB relay, LT bus-bar, graphite electrodes, quality testing of resistive components, low capacity motors, etc.

Application

The high precision micro ohmmeter is used for measuring accurate low resistance with high accuracy, thus making it a reliable tool for quality assurance and easy operations. It comes in handy for quick maintenance checks for process industries. Typically It is very useful in design, test, maintenance, QC/QA, and production. Typical applications include the measurement of:

• Cables
• Electrodes
• Relays
• Components
• Bus Bars
• PC Boards
• Low rating motors & contactors
• Transformers weld joints
• Shunts

Features

• 4½ digits LED display with annunciations
• Resolution of 0.1 μΩ on 2 mΩ range
• Mains cum battery operated (rechargeable Ni-Cd)
• High measurement current of 10A for faster settling of measured values on low resistance
• True four wire resistance measuring technique eliminates lead resistance errors
• Pulse mode with auto hold operation
• Low battery indication to prevent the deep discharge of the internal recharging battery
