[Elecraft] KAT100 tuner.

[Don Wilhelm]

Jean,

The voltage measured at the minimum ideally is zero, but that is not 
usually obtainable in practice.  The actual voltage will depend on the 
power level you used.

Look at the position of the slot in the trimmer capacitor.  If it 
perpendicular to an imaginary line drawn between the two leads, then it 
is either at maximum or minimum capacity - if the slot is at any other 
position, then you have a good minimum.
