Glad you’re getting good use of it!
Right now power factor is not explicitly calculated. From the main text view where you can see AC voltage and current:
- Turn the phone sideways to enter graphing mode
- Touch the “Settings” button in the bottom right
- Touch the button saying “Trend Mode” and wait a few seconds. This will download a complete sample buffer and show you the voltage and current waveforms.
Explicit calculation of the power factor is another item on the app to-do list, but I hope in the meantime seeing the power factor visually will answer your question.
