    Google "DT 9205A schematic" buddy. You'll get all the info you need there.

    Try to download a schematic of the DMM.
    On the schematic, trace the switch functions vs positions and which components they go to.
    Follow the same paths on the PCB switch-tracks.
    Now you can see which circular tracks should be bridged when.
    From there you can align the contacts correctly.
    Some meters also have a 'key', or matching hole/bump for correct alignment.

    Actually you can simply try and discover the correct position to match the writing on the case.
    The switch is a 360 degrees rotatory one,turn it and try to find the diode/continuity position.

    Do this:
    Insert test leads and short them permanently together.
    Rotate the switch till you hear the continuity beep sound.
    Congratulations your meter is oriented.:)
