AbstractContinuously powering the internal temperature-controlled oven provides best accuracy with Zener-diode-based dc voltage references. The hysteresis uncertainties arising from loss of power for two Fluke 732Bs are quantified. This establishes that these instruments can be shipped without battery power between national laboratories without adding significant uncertainty to a comparison.
