Adding Other Tests
To include other tests such as R, simply use extra nodes
to connect directly across the windings in the normal way.
You will have to add and extra 'dummy' winding in the
schematic and use those terminal names in the program.
Adding extra tests in this way does not interfere with
the operation of the constant current drive explained here.
Extending the Constant Current Range
To test very high VA transformers, the drive may be
extended by using an external ac source. 500VA is available from the AT's
