Low Ohm Resistance Testing
<p>Measuring low resistance helps identify resistance elements that have increased above acceptable values. The operation of electrical equipment depends on the controlled flow of current within the design parameters of the given piece of equipment. In the modern age of electronics, increased demands are placed on all aspects of electrical circuitry. A low resistance measurement is typically a measurement below 1.000 ohm. At this level it is important to use test equipment that will minimize errors introduced by the test lead resistance and/or contact resistance between the probe and the material being tested. Also, at this level, standing voltages across the item being measured (e.g. thermal emfs at junctions between different metals) may cause errors, which need to be identified.</p>
