Output voltage of transformer

This is where you type output voltage for your transformer.
Type here exact wanted voltage, program adds to it 6% more value to compensate lost during transforming.
You can use up and down arrows to increase or decrease voltage value.
If you typing number, don't press enter to add that value to list, use add button.

Output amperage of transformer

This is where you type exact output amperage for your transformer. Type value in milliampers (1A = 1000mA).
You can use up and down arrows to increase or decrease amperage value.
If you typing number, don't press enter to add that value to list, use add button.

Add/Change button for adding/changing wanted voltage and amperage to/in lists

This is add/change button, after you type wanted value for output voltage and amperage, use this button to add that values to lists.
If there is selected unlock coil under options then this can become change button.
Selecting one item (value) in voltage/amperage list, values are copied to voltage and amperage boxes for changing.
Clicking now on change button, you are change values in lists from values in boxes.
To return on add button, you can deselect items (values) double clicking on it or select lock coil under options.
When values are in lists, then you can calculate with them.

List of wanted output voltage

There are displayed all output voltages which you want use in calculations.
Selecting item (value) here will automatically select related items (values) in amperage, coils and wire thickness lists.
To deselect, double click on selected value.

List of wanted output amperage

Here are displayed all output amperage in milliampers, which you want use in calculations.
Selecting value here will automatically select related values in voltage, coils and wire thickness lists.
To deselect, double click on selected value.

Delete and Clear buttons

Those buttons are for deleting and clearing values from all output lists.
That includes voltage, amperage, coils and wire thickness list.
Use delete button to remove one selected value and related values from all output lists.
Clear button use for removing all values from all output lists.

Check box option in list

Using this option is possible only if you select unlock coil under options.
This option is useful to adapt some values to maximum power of EI core.

E.g. if you request more output power than core can provide, then check items on list which you want change.
Click on calculate button to recalculate. Items that aren't checked stays fixed and they will not change. All checked items are changed if it's possible. Calculated values are adapt to maximum power which core can provide.

E.g. you want use transformer with maximum core power, type wanted voltage, unlock coil, check all amperage and calculate.

During recalculation, in new values are included 15% more on power and 6% more on voltage to compensate lost during transforming.
