A way to calibrate my ispindel on the fly

[Beer'd Brewing Co]

A way to add specific gravity to a tilt value, as in take a reading in water and record the tilt value as 1.000, then drop the ispindel in the wort after first gravity reading and before fermentation and record that tilt value. Having to reset and adjust in the ispindel config page is a pain in the ass.

can't you do that with an plain old hydrometer and do the math?
