• 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 A.C. or D.C. 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
