Product Description
Motwane’s LR 2045-S is a Digital Micro-Ohmmeter provided with maximum 1A DC current injection and works on the principle of the four wire technique. The four wire technique makes it possible to accurately measure resistance values less than 0.1 Ω while eliminating the inherent resistance of the lead wires connecting the measurement instrument to the component being measured. This instrument is protected against back EMF during inductive measurement and heat run test, which is suitable for resistance measurements of inductive and resistive loads. It has a 4 ½ digits LED display, and resistance measuring range from 1μΩ to 2000Ω. It is user-friendly equipment with a USB for PC interface. The windows based data management software is provided for recording the test results data, and report generation.
Application
Micro Ohmmeter is generally used for bonding contact applications and for measuring extremely low resistance with high accuracy at particular test currents. It is a small portable device that measures resistance and voltage. Typical applications include the measurement of:
- Hot & cold winding resistance measurement of motors, generators, alternators, and transformers.
- Contact resistance measurement of fuses and miniature circuit breakers.
- Resistance measurement of cables & wires.
- Bond testing of aircraft frames.
- Resistance measurement of resistive components (e.g.: resistors, shunts, etc.)
