Mechanical Physician Scale Installation and Operation Instructions - Weighing a Patient 9
5.0 Weighing a Patient
To weigh a patient, have the patient step onto the scale platform and slide the larger poise (shown 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.
6.0 Troubleshooting
For the most accurate weight, always use the scale on a hard, level surface and stand in the center of the platform
with the weight distributed as evenly as possible. If an error occurs or seems excessive, check the following:

Problem Possible Fix
Zero balance of beam The weigh beam must be balanced so the pointer comes to a rest in the
center of the eye loop (shown in Figure 3-1) when both poise weights are set
at zero (see Figure 1-1 for poise weight location). Adjust the balance by
turning the zero adjusting screw at the left end of the weigh beam (see
Figure 4-1).
Beam does not move freely Check if the beam pointer is touching the side of the eye loop in its range of
travel.
Visually ensure that the linkage is centered and properly aligned. Occasionally
during shipping, the alignment will become skewed. The linkage must be free
floating in order for the scale to weigh properly. The linkage can be seen by
looking up underneath the top weigh beam if the scale is slightly tipped to one
side.
Platform rocks excessively When you push down on any corner of the platform, you should not feel any
significant rocking. Ensure scale is setting on a level surface.
Beam does not move at all during a weighment This can be caused by the poise weights being set to a higher weight than the
person’s actual weight. Reset the weights to a lower weight. Also check to
see that the steelyard rod is properly connected and aligned (see Figure 2-6).
Scale is out of calibration Recalibrate the scale by placing a known weight on the scale and moving the
zero adjusting screw to bring the scale back to zero.
