This is a series of short posts on Soil Resistivity Testing. And the common mistakes encountered, with practical advice on how to avoid common mistakes. Part 10 – Soil Resistivity Testing Erratic Readings.
So, when carrying out soil resistivity testing. Erratic readings can occur due to poor connections. Also, through high contact resistance. And background noise at a frequency similar to that used by the measurement equipment. Nearby buried metallic structures, equipment failure, operator error, and other factors.[Read more…] about Soil Resistivity Testing Erratic Readings
