Preparing the Scanner/Scale for Calibration
1. Assure that the scanner/scale is stable, secure and properly installed.
(Refer to
Chapter 2, Site Preparation and Installation, for instruc-
tions on the proper installation of the scanner/scale).
2. Power-up the scanner/scale.
3. Allow the unit to reach temperature equilibrium for at least one
hour. If the scanner/scale is already at room temperature, allow at
least 15 minutes for acclimatization.
4. Before performing the calibration, the scanner/scale must be pre-
stressed with a weight of more than 15kg. With power turned on,
place the entire weight set (including the case) on the weighing sur-
face of the scale. The display should show an underscore and three
hyphens , which is the overweight indication.
5. Remove all weight from the weighing surface and ensure that there
are no obstructions in the debris chutes of the scanner/scale. See
Figure 2-5.
Calibrating the Scale
1. Before proceeding, ensure that the scanner/scale has been prepared
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 obstruc-
tions in the debris chutes.
3. Cut and remove the seal that secures the calibration switch access
cover as shown in
Figure 4-1. The seal may not be present if this is
the initial installation of the scanner/scale.
