1 The 3143 requires no auxiliary grounding rods, making measurement easy. Presenting a next-generation ground resistance meter Grounding is increasingly important for the safe operation and maintenance of communications equipment and many other types of facilities. However, in an urban environment where the ground is covered with concrete or asphalt, conventional measurement methods that require inserting auxiliary grounding electrodes are difficult to use.

2 Count on The 3151 for Dependable Measurements The 3151 is a Standard Ground Resistance Meter Ground resistance measurement involves factors that are not encountered during ordinary resistance measurement, such as polarization of the earth, the influence of grounding current due to leak current and grounding voltage, and the influence of auxiliary grounding resistance.
