Ground measuring devices like the new Fluke 1623-2 and 1625-2 are essential tools for troubleshooting. They help maximize system availability and reduce the risk of electric shock for users. When fault currents do not find a path to ground through a properly designed and maintained grounding system, they follow unintended paths and can even pass through the human body.

In the absence of proper grounding, the likelihood of operational disturbances also increases. Without an efficient grounding system, electrical devices may experience instrument errors, distortion factor and power factor issues, as well as various sporadic faults. Studies show that 25% of power quality problems are attributed to inadequate grounding.
