The ornamental design for an electronicvoltagetesterinstrument, as shown and described.
FIG. 1 is a perspective view of an electronic voltage tester instrument
showing my new design; and,
FIG. 2 is a side elevational view, the opposite side being a mirror image.
It is further noted that the electronic voltage tester instrument is
symmetrical about its center-line axis with the exception of the part
containing the LEDs.
