Quantum Metrology
Even the best wire-wound resistors maintained in the most stable of conditions drift with time and temperature and can exhibit inexplicable changes in value. With the introduction of the MI model 6800 QUANT? (QHR) as the representation of the ohm, previously unattainable levels of repeatability and stability can now be achieved to < 0.02 ppm.
