  Now if the inductance is maximum value then
it is very apparent where Z should be located, either on the input of L
or the output of L.  I believe it general practice to start with maximum
inductance for adjustment of any L network.

        Hmmm...  so it appears the instruction manual
        does not describe the best approach?  I understood
        the user manual to say I should start with zero
        on the Inductor, and the Capacitor at around 2.

        In contrast, based on your description, it appears
        I would be better off starting with the inductor in
        the middle - away from either end - and that starting
        there will make it more obvious what initial capacitor
        setting to select on the BYPASS switch.  I know that
        is not "maximum" - but it would assure that I started
        working against a substantial inductance, rather
        than zero.

Or... have I misunderstood?
