  • Page 9: Functions Of The Device

    FUNCTIONS OF THE DEVICE ■ Easy-to-use device intended for measurement of the loop impedance in a parallel earth network, by a simpler method than the traditional method with 2 auxiliary rods. Loop ohmmeter: measurement of loop impedances from 0.01Ω to 1,500Ω. The ohmmeter function makes allowance for the presence of inductances in the loop, making impedance measurements more accurate at low values.

  • Page 23: Ω+A Position

    5. Ω+A P OS IT ION Since the measurement frequency is audible, the operator hears a discontinuous audible signal (beep-beep). This is neither an operating fault nor an alarm, and it cannot be eliminated. This audible signal is amplified by the presence of current in the loop.
