ABSTRACT:
A printed circuit board having thereon a plurality of conductors including onnection points is tested for insulation resistance between the conductors by measuring current flowing between one conductor and the other conductors in an arrangement whereby each connection point is connectable to a first potential through a first transistor and to a second potential through a second transistor and a current measuring device. During testing, only a single connection point of each conductor is connected to the second potential, and all other transistors of that conductor are mechanically isolated from electrical connection with respective connection points. This prevents leakage current through the transistors associated with the other connection points of a given conductor.
