Abstract

Considering the classic HBM, for the associated human body capacitance (HBC) is generally accepted the value of 100 pF. Developing a method based on the charge preservation and using the Model 6517A as electrometer, we measured for HBC values spread between 50 and 500 pF. This quasi-large dispersion encouraged us to emit and to experimentally verify assumptions regarding the effective values of the HBC, according to different states, circumstances and accepted models. There is good accordance between measured and expected data. One conclusion might be that the classic HBM is rather a conventional and traditional testing standard than a real world universal circuit.
