1 Add the impedance measurement accuracy [%] to the voltage level monitor accuracy
when the DUT's impedance is < 100 .
2 Add the impedance measurement accuracy [%] to the current level monitor accuracy
when the DUT's impedance is  100 .
Accuracies apply when test cable length is 0 m or 1 m. Additional
