Zero Adjustment
To ensure accurate weighments, a zero adjustment should be done to the scale after assembly is complete.
Figure 4-1. Eye Loop Area and Zero Adjusting Screw Location
To perform a zero adjustment:
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.
• Gently press the scale pointer down until it touches the bottom of the eye loop area.
• Release the scale pointer, it rises up and down in the eye loop area. It should settle in the center of the eye loop
area.
3. If the scale does not settle in the center, the small zero balance weight must be adjusted. Turn the zero adjusting
screw using a flat head screwdriver. The zero balance weight moves accordingly.
4. Perform Step 2 again. Continue adjusting the screw until the scale pointer settles in the center of the eye loop area.
