  7. PRS-DMM Programmable Self-Adjusting Resistance Standard
    • Patent pending
    • Software leverages the accuracy of an 8.5 digit DMM, with the versatility of the PRS-300 Programmable Resistor to make the most revolutionary standard resistor ever manufactured
    • Resistance Range: 0.1 Ω to 20 MΩ
    • Resolution: 1 μΩ
    • Accuracies better than 20 ppm; source resistance with the same accuracy that your 8.5 Digit DMM can measure.
    • All you need to do is enter the target resistance. The software uses the DMM to measure the resistance being sourced by the PRS-300 and readjusts the source resistance as close as possible to the target resistance.
