Fairbanks 5001 Series QuickSilver IS - Manual (Page 13)

The equation, NET = GROSS -TARE, is particularly important because it is the
equation that a scale uses to figure net weights in NET WEIGHING MODE. The
gross weight is a function of the weight on the platform and the zero reference.
Tare weight is always an operator defined value.
a. Basic Weighing
1). Turn ON the indicator and the display will go through the warm-up
sequence.
2). When the warm-up sequence is complete, the display should show
zero and the Center-of-Zero indicator should be ON. If it is not, press
the ZERO key.
3) . For GROSS weighing, the NET indicator should be OFF. If it is not,
press the GROSS/NET key until the NET indicator is OFF.
4) . Place the object to be weighed on the platform. As soon as the system
is stable, the weight value will appear in the display.
b. Tare Weighing
1). Turn ON the indicator and the display will go through the warm-up
sequence.
2). When the warm-up sequence is complete, the display should show
zero and the Center-of-Zero indicator should be ON. If it is not, press
the ZERO key. Any tare weight in memory when the scale was turned
off will be lost. A new tare weight must be entered into tare memory.
3). Place the empty container that is going to be used on the platform
and press the AUTO/TARE key. The weight of the empty container
will be entered into memory as a tare weight.
4). Remove the container from the platform. The display will show a
NEGATIVE tare weight value.
5). Place the same or similar container filled with product on the platform.
The display will show the weight of the material in the container.
c. To change the TARE weight value:
1). With no weight on the platform, press the ZERO key. The display will
show zeros and the Center-of-Zero indicator will be ON.
2). Place the new container on the platform and press the AUTO/TARE
key. The old tare weight will be deleted from memory and the new
tare weight entered.
