This intuitively usable precision water level allows for simple measurement of slopes and inclinations, during alignment of frames, the waching machine and much more.If the phone is tilted past 45°, the user interface changes to a second one, which displays a third axis to allow for measurement along all axes. The inbuilt absolute or relative measurement option makes it possible to zeroize from an existing inclination. The hold function freezes current values, so that the user can read specific inclinations more easily. This function further can be configured, for example the threshold of sensibility before values are frozen. Multiple units can be used as graphical representation, so no values need to converted by own calculations.The extensive settings menu offers many different personalizations, e.g. damping coefficients or locking accuracy of the hold function. Calibration of the sensors guarantees best possible accuracy of measured slopes or inclinations.
