How to calibrate Airmatic Suspension on W211 using Xentry DAS?

A brief overview of calibrating the suspension on my W211 using an inclinometer app on my smart phone in lieu of a Romess inclinometer. I did not have a photo of calibrating the front suspension, only a photo of calibrating the rear. In the photo showing the rear voltage value at 2.34 volts, I was under the car confirming the rear axles were at a -1.2 degrees. The original value was close to 3 volts with the rear of the car 1 1/2″ lower and the rear axles were measuring at a -2.8 degrees.

-Straightened steering wheel by adjusting tie-rod ends (was offset to 1:30 o’clock). Set front toe to 0.5mm toe-in each side using string measurement.
-Calibrated suspension using Xentry DAS. Rear suspension sitting too low causing too much negative camber. Right front suspension lower than left front. Corrected.
-Before: ** = “Axle Inclination” (rear) or “Control Arm Inclination” (front) Left Rear Right Rear Left Front Right Front Camber -2.3 -2.3 -1.3 -1.2 Height 25 3/8” 25 3/8” 26 ½” 25 5/8” ** -2.8 -2.8 +2.6 +2.4
-After: ** = “Axle Inclination” (rear) or “Control Arm Inclination” (front) Left Rear Right Rear Left Front Right Front Camber -1.6 -1.7 -1.1 -1.2 Height 26 3/4” 27” 26 ¼” 26 ½” ** -1.2 -1.2 +3.1 +3.1 Note: Rear inclination measured directly off of drive axles; front inclination measured off of “nubs” on lower control arms. Confirmed voltage values within range, then entered new inclination values into Xentry DAS for programming. Successfully programmed suspension control module.
