Earth Ground Resistance

The Macrotest Series easily measures earth ground (2 and 3 Point Method) and soil resistivity (4 Point Method) with an easy to understand graphical user interface and color touchscreen.

The Macrotest Series easily measures earth ground (2 and 3 Point Method) and soil resistivity (4 Point Method) with an easy to understand graphical user interface and color touchscreen. The meter can store internally up to 999 measurements. The included software enables easy data transfer to a computer, tablet or phone via built-in Wi-Fi or USB connection where it can be archived or used to generate reports.

The HTAnalysis application allows users, in real time, to view, analyze, upload and share measurements on the HT Cloud. This is a free app that is available to all.

The Macrotest Series provides a complete set of easy to use measurements.

The Macrotest Series utilizes the three point test (fall of potential), which measures earth ground resistance as required by equipment manufacturer specifications and as mandated by national code requirements for proper grounding. The two point test is used to test grounding wires resistance and connection points resistance between ground system elements (i.e. wires and electrodes). The tester can also be used to test soils for a new ground system design with the 4-point.

More than one earth.

In addition to volt ampere method other testing modes can be adopted as follows:

• Stackless earth ground resistance measurement with T2100 (optional)
  MacrotestG3 adopts an innovative method for earth resistance measurement eliminating the worry of finding a place for auxiliary earth rods. Earth resistance measurement will be easier thanks to an algori- thm HTEarth storing all measurements effected with clamp T2100 and calculating earth resistance value without disconnecting rods.
• Soil resistivity
  It measures soil resistivity ( ) with 4-pole Wenner method.
