Inclination Angle
Measuring range..................-90° to +90°
Resolution ..............................0.1°
Measuring Accuracy...........±1.5° @ -50° to +50°
±2.5° @ -85° to -50° and +50° to +85°
±3.5° @ -90° to -85° and +85° to +90°
Note
Inclination accuracy is specified as the angle between a
vertical and the absolute horizontal plane/true horizontal
baseline. The Product is calibrated to true horizontal 0
°.
