Datalogic Scanning 9504, 9500 manual Scale Adjustments, Zeroing the Scale

Pressing and holding the Volume/Tone Push Button for approximately eight seconds initiates a reset, which is sounded by a rapid number of beeps. If the motor had been spinning, the lamps will blink while the motor spins down. At that point, the motor will spin back up and the scanner will continue to run the Selftest diagnostics. For more informa- tion, see the topic, Power-Up/Selftest & Pre-Operationearlier in this chapter.

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 Zero1 light will turn on and the display will show 0.00 lb (0.000 kg). If it does not, see Chapter 4, Problem Isolation.

4.You have completed the scale zeroing function.

1.Zero light operation is configurable.
