Machine Options dialog box - Level To Gravity tab
The Level To Gravity tab allows you to set up monitoring properties of the Nivel inclination device.
Current Value - Displays the current X-tilt and Y-tilt level values for the Nivel.
Difference - Displays the difference in milliradians between the actual reading of the current X-tilt and Y-tilt values from the current value.
Threshold - Specifies the angle in milliradians that the Nivel level can change and still be considered in tolerance. Otherwise, you need to use the Reset Nivel option on the Options tab.
Monitoring frequency - Defines how often (in seconds) a Nivel monitoring value is read.
