A counter e.m.f. greater than 0.5 V to ground on the + 3.3 V DC / + 5 V DC / + 12 V DC due
to a connected or integrated component can prevent normal operation or even destroy the
computer.
When measuring the counter emf,

plugged in.
During the measurement, all cables from the plant to the computer should be connected.
