The Fluke 1630 earth ground clamp meter simplifi es ground loop testing and enables non-intrusive leakage current measurement. The ground loop testing is also known as "stakeless" earth ground testing. To carry out the measurement there is no need for placing earth stakes and disconnecting the earth system from the electrical installation. The Fluke 1630 combines the two current clamps needed to perform the stakeless ground loop test in one compact and easy to use instrument.
