Using the optional Iclamp these problems can be avoided.

Introducing the ART of ground testing

Ground testing using the ART method is more convenient and reduces testing time.

Model DET3TC includes the additional testing capability called the ART (Attached Rod Technique) method. A nagging problem with traditional ground testing has been the requirement to disconnect the utility connection. Using the ART method you can reliably measure a grounding electrode while still connected and prove it!

Here’s how it works

A current clamp, connected below the point of separation of the parallel test currents, measures only the current flowing through the test ground, not that going back through the utility. This current value is then used by the built-in microprocessor to calculate ground resistance, strictly in accordance with Fall of Potential and supported by IEEE Standard 81.

That’s why using the ART ground testing method is more convenient and significantly reduces your testing time as much as 40%!

For a more detailed explanation of the ART test method we offer these two technical application articles.
