Well, this is where I get corn-fused.
The user manual states it is a REVERSIBLE L-NETWORK, whereby the fixed
capacitors are either placed at the front of the circuit or at the end
of the circuit using the BYPASS switch. I presume the current always
flows in the same direction through the circuit, including the inductor.
(Heck, I am still learning to read schematic diagrams.)
From some of the previous comments, it sounds as if there is some
uncertainly as to the ZERO (0) inductor setting means the most or the
least inductance.
Is this not revealed in the schematic? Or do we have to open the lid
and look to determine the matter? And, would it not be the same from
unit to unit? Some comments seem to suggest the Zero (0) setting could
be different on some units.
Sorry if I missed a point along the way. It is still a mystery to me.

If 0 is maximum inductance.....good. If 0 is minimum inductance.....not
so good. Some value of C is correct for determining the HiZ or LoZ
switch setting initially.

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?
