(1) The maximum permitted value is only limited by the cross section of the primary
conductor. Saturation of the magnetic core of the clamp occurs, which is not dangerous. A
high residual magnetism may remain which can be eliminated by demagnetising the clamp.
(2) Outside hysteresis on DC. (Check zero, no conductor in the jaws).
The intrinsic error is expressed as: ± (% R + phase shift)
