Zero Adjustment
To ensure accurate weighments, a zero adjustment should be done to the scale upon arrival and setup. To perform
a zero adjustment, perform the following steps.
1. Ensure the scale is sitting on a level surface.
2. Check the eye loop area of the scale to ensure that the scale pointer is equally balanced between the eye
loop area. This can be accomplished by gently holding the scale pointer with your finger until it touches
the bottom of the eye loop area. Release the scale pointer and let it rise freely up and down between the
eye loop area until the scale pointer settles in the middle of the eye loop area.

3. If the scale is not balancing properly, then the small zero balance weight must be adjusted. Turn the zero
adjusting screw (shown in Figure 3-1) using a flat head screwdriver. By adjusting the screw, the zero
balance weight will move accordingly.
