How Variable output adapters work:
First determine whether the unit is "center positive" or
"center negative"
This is an example of center positive
|
Next choose the adapter plug that suits your need:

|
This unit has a "screwdriver" adjustment to set the voltage,
which helps to prevent accidental voltage changes. Other
units have "slide switches" which are more prone to
accidental voltage changes.
|
The last thing which must be done is aligning the tip for the correct polarity. If the unit is center positive you align the tip positive on the adapter plug with the tip positive on the cord. If it is center negative
the adapter plug is installed so that the tip positive on the adapter plug & the tip positive on the adapter cord are reversed.
