3.5.5 Measurement of resistance to earth using double clamp method
 The double-clamp measurement may be applied where there is no possibility to use
electrodes driven into the ground.
 The double-clamp method may only be used when measuring multiple earthing (it
is necessary to provide a return path for the test current).
 For ring earth electrodes (step variant ) the method allows switching off to
determine continuity of the measured earth electrode point with the rest of the
earth electrode.
