Extensive measurement functionality: choose the right measurement method for any application
− 4-pole method (Wenner's 4-pole method):
Measure soil resistivity when surveying a grounding design
− 3-pole method:
Precisely measure ground resistance
− MEC (Measuring Earth with a Clamp) function:
Measure ground resistance without disconnecting ground electrodes
− 3-pole method using 4-terminal measurement:
Measure ground resistance values of several ohms or less
− 2-clamp method:
Measure grounding resistance at multiple grounds
− Low-resistance measurement:
Continuity test after ground resistance measurement
