The design is very simple, the whole assembly can be built in a couple of hours. This is an accurate milliohm meter with a maximum resolution of 0.1mOhm. Scullcom Hobby Electronics #31 - Design & Build a Milliohm Meter. The unit will be easy to build and low cost.
Louis Scully Milliohm Meter, Projects In this project we will design and build a milliohm meter which is capable of measuring low resistance from 2 ohm to 0.1 milliohm with an accuracy of 0.1% or better.It is based on a precision current sink and a high-resolution A Estimated Reading Time: 7 mins.
The design is very simple, the whole assembly can be built in a couple of hours once all the parts are gathered.
The milliohm meter calculates the value of the resistor under test (Rx) by measuring the voltage across it and the voltage across a series.
