### Calibration page
http://gravmon.local/calibration.htm
The device page is used to enter gravity + angle/tilt into the device in order to create a formula. Data will be saved on the device and a formula will be checked against the entered numbers for accuracy. Support currently up to 5 values and the more readings the more accurate the formula will be. Its prefeered to use at least 3 values.
