Basing on the ground resistance testing, the cause of unstable resistance readings and negative read- ings were analyzed. It discusses the reasons that affect the deviation from the true value of grounding resistance in addition to the internal factors of the instrument. Then some measures to avoid and reduce the grounding resis- tance deviation are proposed.
