This is 3 ½ digit Contact Resistance Meter which is a digital micro ohm meter designed for measuring resistances in three ranges viz. 200µOhm - 2mOhm - 20mOhm with resolution of 0.1µOhm in 200 µOhm range. This meter can apply DC current, selectable range from 10A, 20A, 50A & 100A to the resistance to be tested. The Resistance reading is displayed directly in micro ohm or milli ohm. This meter is intended to replace complex bridge set up with a single compact instrument. It is based on four wire measurement technique to eliminate the lead resistance error. This meter has custom built backlit LCD with soft touch membrane keypad, data exchange to PCB through USB interface & built in memory storage upto 99 test results.
