1625-2 Users Manual The effectiveness of grounding systems should be checked using a earth/ground tester such as the 1625-2 which checks the effectiveness of connections to the ground. The 1625-2 provides the perfect solution by combining the latest technology into a compact, field-rugged instrument. In addition to performing standard 3-pole and 4-pole ground resistance measurements, an innovative process accurately measures individual earth electrode resistances in single and meshed earthed systems without disconnecting any parallel electrodes. One specific application of this capability is quick and accurate measurement of power pylon grounds. The 1625-2 has automatic frequency control (AFC) to minimize interference. Before measuring, the instrument identifies existing interference and selects a measurement frequency to minimize its effect. Notes • The terms earth and earthing also refer to ground and grounding and is used interchangeably throughout this manual. • For stakeless earth resistance measurements, the Selective/Stakeless Clamp Set (EI-1623) must be purchased. (The1625-2 Kit includes this clamp set.) • Selective measurements are described in the main section of this manual.
