    Testing Methods

    • 3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
    • Selective testing – without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp
    • Stakeless testing – innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance
    • One-button measurement concept
    • 3- and 4-pole earth ground measurement
    • 4-pole soil resistivity testing
    • Selective testing, no disconnection of ground conductor (1 clamp)
    • Stakeless testing, quick ground loop testing (2 clamps)
    • Measuring frequency 128 Hz
  • RA 3-pole Ground Resistance Measurement (IEC 1557-5)
    Measuring voltage Vm = 48 V ac
    Short circuit current > 50 mA
    Measure frequency 128 Hz
    Resolution 0.001 Ω to 10 Ω
    Measuring range 0.001 Ω to 19.99 kΩ
    Intrinsic error ± (2 % of reading + 3 digit)
    Operating error ± (5 % of reading + 3 d)
    RA 4-pole Ground Resistance Measurement (IEC 1557-5)
    Measuring voltage Vm = 48 V ac

    RA 3-pole Ground Resistance Measurement With Current Clamp
    Measuring voltage Vm = 48 V ac
    Short circuit current > 50 mA
    Measure frequency 128 Hz
    Resolution 0.001 Ω to 10 Ω
    Measuring range 0.001 Ω to 19.99 kΩ
    Intrinsic error ± (7 % of reading + 3 d)
    Operating error ± (10 % of reading + 5 d)
    RA 4-pole Selective Ground Resistance Measurement With Current Clamp
    Measuring voltage Vm = 48 V ac
    Short circuit current > 50 mA
