6 Mechanical Baby Scale Installation and Operation Instructions
4.0 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 upright on a level surface.
2. Make sure that the poise weights are pushed all the way to the left hand side (at zero) making sure that the
large poise is firmly seated in the notch and the small poise is firmly against the shoulder of the beam.
3. Check the eye loop area of the scale to ensure that the scale pointer is centered.

4. If the scale is not balancing properly, then the small zero balance weight must be adjusted. Turn the zero
adjusting screw (shown in Figure 4-2) using the enclosed multi-purpose tool. Depending on the direction
the zero balance weight will move accordingly.

5.0 Weighing a Baby
To weigh a baby, place the baby on the weigh platter and slide the larger poise (on bottom) to the approximate
target weight. Next move the smaller poise on top until the weigh beam balances and the scale pointer is centered
within the eye loop area as shown in Figure 4-1.
