4 Wire Low Resistance Standards

4 Wire Low Resistance Standards are extremely high precision designed for calibration and laboratory use. The terminals use one pair to carry an operating current and the other pair to measure the voltage drop. These also eliminate the errors caused by voltage drops across the lead resistances, as no charge flows through voltage sensing leads. Besides, these 4 Wire Low Resistance Standards use the latest advances in materials and processing for high stability and immunity from changes in ambient environment.
