Calibrating the Scale (Pounds & Kilograms)

1.Before proceeding, ensure that the scanner/scale has been pre- pared for this process by performing the preceding steps titled, Preparing the Scanner/Scale for Calibration.

2.Remove the weigh platter and make sure that there are no obstructions in the debris chutes.

3.Cut and remove the seal that secures the calibration switch access cover and remove the cover. This seal may not be present if this is the initial installation of the scanner/scale.

To protect static sensitive circuitry, follow Electro-Static Discharge (ESD) procedures when exposing internal scanner-scale components.

ESD ALERT

4.Locate the calibration switch access cover and remove the screw that holds the cover in place. (See Figure 5-1).

5.Press and release the Calibration Switch to place the scanner/scale in Calibration Mode (See Figure 5-2). The scanner/scale will sound a tone indicating that it is in Calibration Mode. If the motor was spinning when you initiated Calibration Mode, the motor will stop and the Yellow LED will begin flashing indicating the scale is in Calibration Mode. The display will show the mes- sage “ESCL” (empty scale).

6.Reinstall the weigh platter.

7.Press the Zero Push Button. The Yellow LED will go out for approximately 10 seconds (or less) and the Remote Display will

alternately display and until the scale is ready to proceed.

8.When the scale is ready, the Yellow LED will begin blinking again and the display will show the message “Ad20 (add twenty pounds)” or “Ad10 (add ten kilograms).” The scanner/scale will also sound one tone if the scale is weighing in kilograms or two tones for pounds. Place the correct weight (twenty pounds for cal- ibration in pounds, or ten kilograms for metric calibration) from
