Exercise Sheet 3-3-1
Leveling the Scale
Tools and Materials Needed:
 3-mm hex key
 9/64-inch hex key
 Lab gloves
 Set of calibrated weights
 4-mm inch hex key
 Level
 Tweezers
1. Use the 3-mm hex key and the 4-mm hex key to remove the screws in the dispensing
area front plate.
2. Remove the dispensing area front plate and place it in a safe place.
 Lay the plate down on a flat surface. Do not stand it on edge or lean it against
something as this may bend the plate.
3. Gently apply pressure to opposite corners of the scale base to determine its all-around
stability.
 The scale base should not be rigid. It should compress and move up and down, but
it should also be stable.
4. Locate the four leveling screws on the underside of the scale base. There is one screw in
each corner of the base.
 You need to look up inside of the lower front cabinet to locate the scale leveling
screws.
5. If the scale needs to be stabilized, use the 9/64-inch hex key to adjust the corner or
corners of the scale base that need to be adjusted in order to stabilize the scale.
 Tightening a screw lowers that corner of the scale base. Loosening a screw raises
the corner.
6. Once the scale is stabilized, locate the bubble level along the left hand edge of the scale
base.
7. Determine the position of the bubble, and determine which side of the scale needs to be
adjusted to level it.
 The scale is level when the bubble is within the circle outline. If the bubble is to the
left of the circle, the right side of the scale needs to be raised. If the bubble is
towards the rear of the circle, the front of the scale needs to be raised.
8. Once the scale is level, check it again for all-around stability. Stabilize the scale if
necessary.
9. Re-level the scale if necessary.
10. Replace the dispensing area front plate.
