XC880A OWNERS MANUAL
2.2
Weighing Operations
2.2.1
Zeroing The Scale
During regular use, the displayed weights may shift due to
temperature changes or load cell fluctuation. The XC880A may be zeroed
at any time by pressing the ‘ZERO’ key. The XC880A will read the
weight until motion is within the allowable window, then that weight
becomes the new zero point.
Should the operator inadvertently press the ‘ZERO’ key with
weight present on the scale, the previous zero value can be restored by
pressing ‘SHIFT’ followed by the ‘ZERO’ key.
2.2.2
Changing Units
The XC880A will display weight and calculate quantities using 1
of 4 possible units of measure, Pounds, Kilograms, Grams, and Ounces.
The operator may toggle through the choices by pressing the ‘SHIFT’ key
followed by the ‘6’ (units) key. If the key is released immediately, the
units setting will be toggled to the next choice, and the display will change
accordingly. If the key is held down, the alphanumeric LCD displays the
available unit choices one at a time. When the desired choice is displayed,
simply release the key and the currently displayed unit will become the
active units setting. The proper LED on the front panel will also be lit to
indicate the current unit of measure.
2.2.3
Tare Weights
The XC880A allows the user to remove tare weight in one of two
Methods, pushbutton, or direct keyboard entry.
Direct Tare Entry
: If the tare weight is known, the user may
enter it directly through the keyboard, and press the ‘TARE’ key. If the
entered value is not greater than the scale capacity, it will be removed
from the displayed weight, and the XC880A will enter the net weight
mode.
Auto Tare
: The user may tare the container weight by placing an
empty container on the scale and pressing ‘SHIFT’ followed by the
‘TARE’ key. The XC880A will sample the weight until stable. If a valid
tare weight is present, the XC880A will enter the net weight mode, and
display the net weight.
Clearing the Tare Weight
: The tare weight may be cleared by
pressing ‘SHIFT’ followed by the ‘RESET’ key, or by entering a tare
weight of 0.
Displaying the Tare Weight
: Pressing, and holding the ‘TARE’
key, while in net weight mode will display the current tare weight on the
alphanumeric display. It will be displayed until the ‘TARE’ key is
released.
