    Hi

    Start LTSpice, open the .cir file from the "file" menu, click anywhere in the file to be sure its active, then click the Run button (Running Man symbol). A plot screen should then display.

    Then,

    RHT-cLk in the file window, and select "Visible Traces" from the menu, then select the values specified by this statement:

    .PRINT TRAN V(1) I(VSENSE1)

    The selected values should be V(1) and I(VSENSE1) and should be displayed in the plot screen.

    see attached

    I am looking at this site and on it is a screenshot of a circuit.

    On the far left is a symbol with an arrow.

    Does anyone know what this is?

    Not as important but... on the right hand side the E_EMF part seems to have a second set of + - signs where the wires intersect... I cannot get my LTSpice schematic to do this, I just get typical joins.(blue little squares)

    Is this a trick I am missing?

    Almost done.

    Just seeming to have issue having the sub circuit be recognised by the other files.

    I have :

    .asc
    .asy
    .cir

    files.

    The tutorial mentions an include directive, but its not really shown.

    I get an error missing schematics of the hierarchy.

    Can anyone help me work it out?

    I thought post number 5 just showed how to run the .cir file?

    I have managed that and it isn't really what I require.

    I am now after doing something a little different

    cheers

    The symbol on the far left is a F element or CCCS (current controlled current source). The one one the right is an E element or VCVS (voltage controlled voltage source)

    You should be using the E element in the sym folder..it is a 4 terminal element.
