    It allows to take the measurements of:

    • earth resistance using auxiliary electrodes,
    • earth resistance using auxiliary electrodes and clamp (for measurements of multiple earthing)
    • earth resistance using double clamps for measuring multiple earthing without underground connections,
    • impulse earth impedance (without disconnecting measured earthing),
    • ground resistivity (Wenner method),
    • current using the clamp (e.g. leakage) and flexible clamp (Rogowsky coil),
    • measurement of continuity of equipotential bondings and protective conductors (meeting the requirements of IEC 60364 - 6 - 61:2000 section 6.12.2) with auto-zero function – with current 200 mA.

    Additionally:

    • measurement of resistance of auxiliary electrodes RS and RH,
    • measurement of interference voltage,
    • measurement of interference frequency,
    • measurement in the presence of interference voltage in the power network
      with frequency 16 2/3 Hz, 50 Hz, 60 Hz and 400 Hz (with automatic selection of proper frequency of measuring signal or with manual selection),
    • selection of maximum measuring voltage (25 V and 50 V)
    • introducing the distance between the electrodes for the resistivity in metres (m) and feet (ft),
    • memory of 990 measurements (10 banks of 99 cells each),
    • calibration of clamp used,
    • real time clock (RTC),
    • data transmission to the computer USB and Bluetooth*,
    • indication of battery state.
