After completing the Shift Test, you must complete the Increasing Load Test using 20.0, 25.0
and 30.0 pounds of weight.
NOTE
SINGLE INTERVAL DUAL INTERVAL
After completing the Shift Test, you must complete
the Increasing Load Test using 20.0, 25.0 and
30.0 pounds of weight.
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 20.0
pounds in the center of the weighing surface
and check that the display reads between 19.99
and 20.01 lb.
1. With the scale starting at zero, place 20.0
pounds in the center of the weighing surface and
check that the display reads between 19.99 and
20.01 lb.
2. Place an additional five pounds in the center of
the weighing surface, increasing the load to
25.0 pounds and check that the display reads
between 24.99 and 25.01 lb.
2. Place an additional five pounds (25 pounds total)
in the center of the weighing surface. Check that
the display reads between 24.99 and 25.01 lb.
3. Place an additional five pounds in the center of
the weighing surface increasing the load to 30.0
pounds and check that the display reads
between 29.99 and 30.01 lb.
3. Place an additional five pounds in the center of
the weighing surface increasing the load to 30.0
pounds and check that the display reads between
29.99 and 30.01 lb.
4. Remove the weights and verify that the display
reads 0.00.
4. Remove the weights and verify that the display

5. You have completed the Increasing-Load Test
(Phase 2)
5. You have completed the Increasing-Load Test
(Phase 3).
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 five pound increments
only up to the upper weight limit set for your scale.
Blanking Test
This test ensures that the scanner/scale will indicate its weighing capability has been exceeded
if a weight greater than 0.05 pounds over its maximum upper weight is placed upon the
unit.
1. Place weights that total the upper weight limit plus 0.051 pounds
on the scale. For
example: If the upper limit is set at 30 pounds, place weights totaling 30.051 pounds
on the scale.
2. Verify that the display shows a dash and three hyphe
ns (_ - - -). This is the overweight
indication.
NOTE
The scanner/scale may blank (show an underscore and three hyphens) at any
weight greater than its upper weight limit, but
must blank when the upper
weight limit plus 0.051 pounds are set upon the weighing surface.
