Associated Research 251 Vibroground (3 Point)
- 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 leads ( terminals 1 & 2 only)
- Stray AC or DC currents in the earth do not detract from its accuracy
- Three resistance ranges: 0 to 12 ohm, 0 to 120 ohms, 0 to 1200 ohms
Applications
- Three Electrode Method, for determination of average earth resistivity.
- 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
