Soil Resistivity Testing Method -The Schlumberger Array

The Schlumberger array is a geotechnical investigation method which determines the electrical resistivity of the soil. This is similar to the Wenner probe test, but it uses multiple current electrodes rather than just two. This allows for a more detailed and accurate measurement of soil resistivity.

Soil resistivity testing carried out using different methods, this is another of the three popular approaches to perform soil resistivity testing:

Soil Resistivity Testing Method – Driven Rod

The driven rod test is a geotechnical investigation method which determines the resistance of soil to the penetration of a rod or other penetrometer. 

The Soil resistivity is determined using different Soil Resistivity Testing methods. However the Driven Rod, described below is the last of the three most popular Soil Resistivity Testing methods we use to measure the soil resistivity.

Soil Resistivity Testing Erratic Readings

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.

Soil Resistivity Testing Background Noise

Soil Resistivity Testing 10 Common Mistakes

This is a series of short posts on Soil Resistivity Testing and the common mistakes encountered, with practical advice on how to avoid Soil Resistivity Testing 10 Common Mistakes.

Soil Resistivity Testing Background Noise – Due to nearby sources of 50 Hz (or 60 Hz) current and its harmonics, electrical noise at these frequencies is expected in the measurements, particularly for the larger electrode spacings. [Read more…] about Soil Resistivity Testing Background Noise

Soil Resistivity Testing Weak Signal

Soil Resistivity Testing 10 Common Mistakes

This is a series of short posts on Soil Resistivity Testing and the common mistakes encountered, with practical advice on how to avoid Soil Resistivity Testing 10 Common Mistakes.

A Soil Resistivity Testing weak signal can result from a low-power source, a low-voltage source, or a high contact resistance of one or both of the current injection electrodes. [Read more…] about Soil Resistivity Testing Weak Signal
