NOTE: For convenience, pinpoint test il
lustrations indicating voltage measurements do not always accurately reflect the
conventional method of connecting a multimeter. More explicitly, if the multimeter probes are connected as shown in some
illustrations (positive probe to ground), the voltage reading would be preceded by the negative sign '-', indicating that the
probes have been connected in the reverse manner to the norm al convention. The accuracy of the reading is not affected
and the '-' sign can be ignored when comparing the reading with the results indicated in the text of the pinpoint test.
