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. The 3143 uses a new measurement principle that makes auxiliary grounding electrodes unnecessary, so it can be used to measure ground resistance on paved roads.

Notes on Usage:
The 3143 is particularly useful for measuring the earth resistance of single rod electrodes found among aerial transmission line equipment and various types of safety box circuits, and incorporates a measurement principle that is different from that of the Earth HiTESTER 3151.

Ground resistance 20.0 to 49.9 ohm (±10 % rdg.), 50.0 to 500.0 ohm (±5 % rdg.)
Principle of operation Voltage comparison method (Measurement of voltage at loop impedance serial resonance)
Open circuit voltage: 0.9 V ACpeak typ. Testing current: 3.6 mA AC max. with terminals shorted, Testing frequency: 100 kHz to 1.5 MHz
