BEHAVIOUR OF HIGH VALUE STANDARD RESISTORS VERSUS RELATIVE HUMIDITY: FIRST EXPERIMENTAL RESULTS

• Abstract:

  In this paper we report the first experimental results in the characterization of high value standard resistors versus relative humidity. For this aim we adopted a digital multimeter (DMM) based measurement method, already used for characterization of high value resistors versus temperature and applied voltage and to participate in the CCEM-K2 comparison on high resistance. For the realization of the environment with specific values of relative humidity we realized a thermostatic enclosure in which it is possible to set the desired humidity value in the range (10 ÷ 90)% with a long term instability of the humidity up to ± 1%. The preliminary experimental results of characterization suggest us that the value assigned to a high value standard resistor is affected not by the humidity during the calibration period, but by the humidity with which it was maintained several days or weeks before calibration.
