Now you must connect the windings to the test nodes of the tester:
Place the mouse pointer over terminal A; press and hold the right mouse button.
Continue holding this mouse button down and drag the mouse pointer to test
node 9. Release the button. A wire will now connect terminal A to test node
9.Repeat this procedure to connect the other three terminals, B, C and D to nodes
7, 10 and 8. The screen should now look like this:
You have now created a schematic layout of a four terminal transformer.
CREATING THE TEST PROGRAM
After creating the transformer schematic, you may now create an example program,
containing the following four tests:
Resistance of winding AB (59 to 73Ω)
Resistance of winding CD (59 to 73Ω)
Inductance of winding AB (>3H)
Turns ratio AB to CD (1:1 ± 2%)
(It is probable that the actual program used to test such a transformer in production
would be the same four tests, plus an additional insulation resistance (or Hi-Pot) test
to check for winding to winding isolation. This last test has not been included in this
tutorial as it would require the use of safety interlocks.)
