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 programmable 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 typically better than 10 ppm.
  • Software automatically provides the measurement uncertainties of every measurement
  • When you buy PRS-300, there is no additional cost for this PRS-DMM software
  • If you already own a Fluke 8508A or a Keysight 3458A 8.5 Digit DMM, this is the most cost effective way to have an precision resistance source in your lab
  • No need to worry about resistors going out of tolerance (long term stability) or accounting for zero/switch resistance
  • No calibration or maintenance costs required, when used with an 8.5 digit DMM
  • Will have lower long-term operating cost than traditional manual decade resistors like 1433 or HARS-X
  • Very easy to use with little to no training required; no need to understand programming
