Associated Research 263 Vibroground (4 Point)
Features
- Self-contained synchronous vibrator, battery powered unit
- Capable of measuring earth resistivity or the true resistance to earth of man-made grounds
- Not affected by the resistance of the auxiliary probes or leads
- Stray AC or DC currents in the earth do not detract from its accuracy
- Four resistance ranges: 0 to 1 ohm, 0 to 10 ohms, 0 to 100 ohms, 0 to 1,000 ohms
Applications
- Four Electrode Method, for determination of average earth resistivity. The ranges provided in the instrument make possible accurate soil resistivity measurements from 0 to 1,915,000 ohms per cubic centimeter at 10 ft. or greater spacing
- Three Electrode Method, for the measurement of resistance to earth of man-made grounds, anode resistance, polarization effects
- Two Electrode Method, for the measurement of circuit resistance
- Available with ground rods & cable set
