Abstract:The effects of the contact resistance of the electrode on the amplitude measurements and phase measurements were escribed. The methods of removing the effects caused by variable contact resistance of elec-trode and improving the precision of observation for amplitude and phase in the field measurement were also dis-cussed.
Key words: high precision measurements contact resistance principle of compensation phase difference
