Align the turret

Always perform an alignment after changing turret types (from the 2-mL vial
turret to the 4-mL vial turret, and vice-versa).
1. Remove all vials from the turret. Open the injector door and remove the
syringe.
2. Remove the needle support assembly. See “Replacing the needle support
assembly” on page 224.
3. Push the align button. The injector and turret will perform a series of
checks.
4. Loosen the screws in the clamps that hold the calibration probe to the
bottom of the turret and remove the probe. Do not remove the clamps.
