key. The new tare will be entered, the weight display will show 0.000 lb and the NET annunciator will
illuminate.

tare value.

After a tare value is entered into the scale, items placed on the scale will cause the net annunciator to illuminate

weight is shown below:

will no longer be illuminated. The unit weight and the quantity displays go blank.
