Scale Adjustments
The scale allows two user adjustments: zeroing and calibration. The first,
and most frequently performed, is ‘zeroing’ the scale. This operation resets
the scale’s “at rest” reading to zero which must be within the range of - 0.2
pounds (- 1.25 grams) to +0.6 pounds (0.27kg) since the last calibration.
While the ‘at rest’ reading remains within the zero range, the scale will
automatically adjust itself to true zero. The scale also automatically zeros
itself on power-up if the weight present on the scale is within these defined
limits.
Zeroing the Scale
The zeroing operation may be performed by checkers and other store per-
sonnel. Pressing and releasing the Scale Zero Push Button should return
the scale to Normal Operation. If the zero point moves out of the zero
range due to debris accumulation or other causes, pressing the Scale Zero
Push Button will not reset the zero point. In this case the weigh platter
must be cleaned, debris chutes cleared of debris or the scale must be recal-
ibrated.
With the scanner/scale powered-up and at operating temperature:
1. Remove everything from the weighing surface of the scanner/
scale.
2. Press the Scale Zero Push Button. (See Figure 1-1).
3. The Zero
1
light will turn on and the display will show 0.00 lb
(0.000 kg). If it does not, see Section 4, Problem Isolation.
4. You have completed the scale zeroing function.
Calibrating the Scale
The second adjustment, calibration, defines and sets a standard reference
weight range against which all product weights are compared. If your scale
is set for weighing in pounds, this range is 0 - 30 pounds, and, if your scale
is set for weighing in kilograms, the range is 0 - 15 kilograms. The scale
must be calibrated upon initial installation, whenever the scale cannot be
zeroed, when the scale diagnostics indicate a calibration error, when the
weighing measure (pounds or kilograms) is changed, or when the scale
module has been replaced.
1. Zero light operation is configurable.
