Hangdown Ribbon Replacement . 73
platinum ribbon above the glass ball resting in the flared capillary tube.
14. Slightly lift and rotate the ribbon to correct the alignment. This may take a few tries
but it is extremely important to obtain the alignment shown below.
15. Carefully inspect (using a magnifier, if necessary) the position of the platinum ribbon
within the capillary tube below the glass ball. It must hang straight down without
touching the inner wall of the capillary tube. If it touches, the ball must be lifted
slightly to allow the ribbon to center itself within the tube.
If you replaced the tare weight ribbon, go to step 17.
16. After centering the ribbon in the capillary tube on the sample hangdown wire side,
check that the rotational alignment of the sample pan has not been disturbed. If so,
repeat steps 14 and 15.
17. Locate and open the tube of rubber cement (P/N 09923480). Apply a tiny amount of
cement to the end of the wire rubber cement applicator (P/N N5376742). Touch the
cement to the area between the glass ball and the flared capillary tube.
NOTE: Take great care not to disturb the position of the ball.
Repeat this step until you have placed cement around the circumference of the glass
ball.
NOTE: Be very careful not to apply too much rubber cement in one area such that it runs down the
capillary tube.
18. Allow 10 minutes for the glue to set.
Inspect the work to ensure that adequate cement was applied. You can test the
cement by gently trying to remove the ball from the flared capillary tube by pulling
on the ribbon above the ball. The ball should not move.
Re-inspect the section of the ribbon within the capillary tube. It should hang freely.
19. Replace the dome on the balance plate assembly, taking care not to touch any
components.
