The 20 position manual Rotor Switch will be used for the
initial tests of the DK power supplies.   This Rotor Switch
setup is left over from previous projects.

This Rotor Switch is basically a  2 pole  20 position
switch.

  - The left-hand knob is labeled:  0, 11, 12, ... 19, 20.

    When set to "0" this switch selects the right-hand
    switch for the input signal pair.

    When set to:  11, 12, ... 19, 20  this switch selects
    that connector pin pair as the input signal pair.


  - The right-hand knob is labeled:  1, 2, ... 9, 10.
  
    When set to one of these 10 values, this switch selects
    that connector pin pair as the input signal pair.


This switch is 2 pole  so both the HI side and the LOW side
of the Voltmeter that this Rotor Switch is typically used
with are connected to the appropriate connector pin pair
in the Power Supply Monitor Connector - J11 on the DK Board.

A concern is making certain that the Voltmeter that you are
using  responds only to the DC value of a given power supply
bus  and  not  to any high frequency digital circuit induced
noise that may be on that bus or on the associated ground pin.
