The Motwane make Contact Resistance Meter (Model: CRM 100A) is a digital micro ohm meter designed to measure extremely low resistances. The Instrument is based on 4-wire measurement of low resistance to eliminate the effect of lead resistance of 2 wires method using high Direct Current. The instrument is designed to replace complex bridge set up with a single compact instrument. Current injection is in steps of 10A, 20A, 50A and 100A. The testing information is displayed on large LCD with backlit, real time data is displayed during the test ON condition. The instrument gives a high resolution of 0.1μΩ on 200 μΩ resistance range. The instrument is easy to operate and user friendly. Accessories are rugged and come with heavy duty clips for better grip on test object. The kit and accessories are housed in a trolley mounted casing for easy transportation. Advanced Windows based software is provided for data downloading, analysis and report generation. The instrument can be operated through software. Internal memory is provided for onsite data storage.
