So I know that if the display is to the right the Disto tends to reassure an Azimuth 2 degrees to high and if the display is to the left.
And when the display is to the left it tends to give an Azimuth 1 degree to low.

The main source of error could be misaligned back side of Disto with station point especially together with short distance to measured station. There is a way to reduce this error to minimum when the back extension aligned with laser beam of the Disto is used.
