Fairbanks 5001 Series QuickSilver IS - Manual (Page 12)

B. Indicators:
NET When ON, indicates the scale is in the NET mode. When OFF, indicates
the scale is in the GROSS mode.
lb Indicates the scale is using pounds as the unit of weight.
kg Indicates the scale is using kilograms as the unit of weight.
oz Indicates the scale is using ounces as the unit of weight.
g Indicates the scale is using grams as the unit of weight.
Center-of-Zero Indicates the scale is at the zero point and is ready to
weigh.
C. Weighing
Remove any weight from the platform. If the instrument is OFF, press and hold the ON
key until the display comes on (not blank) and the indicator begins its initiation
sequence (the PROM # and Revision will be displayed briefly i.e., 11754.3). The scale
will begin operations in the Gross Weighing Mode.
The Zero function, Auto Tare function, and AZT require the displayed weight to be
stable before these functions will operate. The weight reading is stable if the variation
in weight is less than the programmed motion range. If the rate of change in weight is
less than 2.5 times the motion range every second, then the weight is stable.
1. Instrument Weighing Functions
The industry uses three terms which describe the apportionment of an object's
weight. These terms are GROSS WEIGHT, TARE WEIGHT, and NET WEIGHT.
• Gross weight is the total weight of an object. This would include any
incidental materials as well as the primary materials which comprise
the object.
• Tare weight is the weight of the incidental materials.
• Net weight is the weight of the primary materials. Tare weight and Net weight
together equal the Gross weight.
Example: A can of house paint is an object to be weighed. The can is incidental
material used to hold the primary material, paint, and the label is incidental
material used to identify the paint. All of the incidental materials taken
together make up the tare weight. All of the primary materials' weights
together make up the Net weight; in this case pigment, vehicle, and solvent.
The object is made up of incidental materials, can and label, and primary
materials, paint. Taken together, this is the gross weight.
The three weights can be expressed in terms as follows:
GROSS = NET + TARE
TARE = GROSS - NET
NET =GROSS - TARE
