2. Long press on entry field does eventually bring it up, but app erases my entry when I try to move to the next field.

3. It's just a form not a calculator.The app is great sir, how about in generators or in parrallel connection of transformer mean 2 or more supplies.

4. Uninstalled.I purchased a Samsung galaxy 5 and when I downloaded this app I found that there's no decimal in the calculator for the impedance value, so please fix.

5. Values aren't 100% but it's close enough.WonderfullInstructorEquipment x/r ratios is not taken into account in calculations.

6. When I get to entering kva and voltage, app does not bring up keypad.

7. Great app for a quick verification of fault at any point of the system.

8. Thank you.It wants you to fill in every field including aic.

9. Hence, highly inaccurate calculated fault current values.

10. Installed software, tried to use it on a 3 phase circuit.

11. Thank youUse this app all the helps with NEC 110.9 and 110.10 applicationsEasy to use.
