To install the balance reverse the above procedure.
Check that the balance is level by using a dental mirror to view the bubble gauge at the back
of the balance. Adjust the front legs of the balance to get the bubble in the middle of the circle.
Once this is complete loosen the 2 x 4mm allen screw which secure the balance base plate to
the instrument frame and gently slide to align the balance pedestal central to the hole in the
lower furnace. Check also that the base plate is aligned and square to the frame. Tighten the
base plate allen screws to secure balance in this position. Place a crucible in the carousel and
check for correct alignment and clearance. Adjust as required to finalise this procedure.
