Adjusting the Furnace . 63

The TGA 8000 is now ready to be calibrated.

Adjusting the Convection Iris

Lift the top cover of the analyzer up to access the balance dome.

Remove the balance dome by turning the locking devices and pulling the arms out of

the groove in the dome. Lift the dome straight up and away from the balance. The

iris is now exposed.

Open the iris all the way by pushing the arm clockwise.

Loosen the screws on the two stands that hold the iris in place.

Move the iris around until the hangdown wire is centered in the iris.

When the hangdown wire is centered, tighten the screws on the stands. Do not

overtighten; the iris arm will not be able to move.

Close the iris as far as possible without it touching the hangdown wire by turning the

lever counterclockwise.

Replace the dome back onto the balance plate and lock in place.

Lower the access cover.
