3.1.2. Device mechanical alignment
For best measurement accuracy, a good mechanical alignment is required. During manufacturing, the
Apogee measurement frame has been carefully aligned to 0.02° with the base plate for roll, pitch and yaw
angles.
To ease the yaw alignment (X axis), the base plate features two alignment holes Ø 4 mm H8 that
guarantees with two taper pins Ø 4 mm h7 a yaw alignment better than ±0.04°.
