When using this scale, the weight of an object, such as a portable oxygen tank, can be
subtracted from the total weight in order to determine the weight of the patient alone.
Weighing a Patient and Taring an Unknown Weight:

scale will automatically deduct the weight of the object and only displ
ay the patient’s weight.

the display. Press the
ZERO/TARE
