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.
