Calibration Procedures
Increasing- Load Test (Phase 2 Dual Interval)
Shift Test (10 Pounds)
The Shift Test checks to ensure that items placed anywhere on the weighing surface of the
scanner/scale are weighed properly. Refer to
SINGLE INTERVAL
1. Place and remove in succession, a ten-pound
load on the center of each of the four quadrants
(1, 2, 3, and 4 in
scale's weigh platter. Verify that a reading of
between 9.99 and 10.01 lb registers under load
and that the display returns to 0.00 between
each load.
2. After verifying the accuracy of each quadrant
of the weighing surface, remove all weight
from the scale. You have completed the Shift
Test.
82
The upper limit of the scale is configurable according to the POS interface
type and may not necessarily be set at 30 pounds, which is the standard
setting. For this test, continue to place weights in two pound increments
only up to the upper weight limit set for your scale.

DUAL INTERVAL
After completing the Shift Test, you must complete
the Increasing Load Test using 8.0, 10.0 and 12.0
pounds of weight.
1. With the scale starting at zero, place 8.0 pounds
in the center of the weighing surface and check
that the display reads between 7.995 and 8.005
lb.
2. Place an additional two pounds (10 pounds
total) in the center of the weighing surface.
Check that the display reads between 9.995 and
10.005 lb.
3. Place an additional two pounds in the center of
the weighing surface increasing the load to 12.0
pounds and check that the display reads
between 11.995 and 12.005 lb.
4. Place an additional five pounds (fifteen pounds
total) on the center of the weighing surface. Ver-
ify that the Remote Display reads between
14.995 and 15.01. Remove the weights and ver-
ify that the display reads 0.00.
5. You have completed the Increasing-Load Test
(Phase 2).

DUAL INTERVAL
1. Place and remove, in succession, a ten-pound
load on the center of each of the four quadrants:
1, 2, 3, and 4, (as shown in
scanner/scale's weigh platter. Verify that a read-
ing of between 9.99 and 10.01 lb. registers,
under load, in each quadrant tested. Check that
the display returns to 0.00 between each load.
2. After verifying the accuracy of each quadrant of
the weighing surface, remove all weight from the
scale. This completes the Shift Test.
