Aligning the Vial Loader (G1289/G1290 only)
Every three months, Agilent recommends that you check the vial loader to see
if it needs adjustment. This helps prevent vial handling problems.
This procedure uses the Advanced Function keys to pick up and move a vial
from the sample tray to the oven port. At the steps where the fork picks up or
releases the neck of a sample vial, you will check to see if the fork and vial are
lined up properly.
If there is a misalignment between the vial and the fork, you will adjust one or
more of the six potentiometers that control the positioning of the loaders and
the vial gripper fork. These potentiometers are located in the horizontal loader
arm. You will need to remove the horizontal loader back cover to adjust them.
The procedure to adjust the potentiometers is described below. The procedure
to check vial loader operation starts on page 99.
