8 Mechanical Physician 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, carry out the following steps.
1. Ensure the scale is sitting 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 equally balanced between the eye
loop area.

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 4-1) using a flat head screwdriver. By adjusting the screw, the zero
balance weight will move accordingly.
