Decreasing-Load Test
This test ensures that the scanner/scale responds properly when a heavy object is followed by
a significantly smaller object.
NOTE
SINGLE INTERVAL DUAL INTERVAL
1. Place weights that total 15.8 kilograms. 1. Place weights that total 15.8 kilograms.
2. Remove weights to leave 10 kilograms on the
scale and verify that the display shows between
9.990 and 10.010 kilograms.
2. Remove weights to leave 10 kilograms on the
scale and verify that the display shows between
9.990 and 10.010 kilograms.
3. Remove an additional 9.00 kilograms from the
scale and check that the scale reads 1.000 kg.
3. Remove an additional 4 kilograms from the scale
and check that the scale reads between 5.998 and
6.005 kg.
4. You have completed the Decreasing Load Test. 4. Remove an additional 2 kilograms from the scale
and check that the scale reads between 3.998 and
4.002 kg.
5. Remove an additional 3 kilograms from the scale
and check that the scale reads 1 kg.
6. You have completed the Decreasing Load Test.
If the upper weight limit for your scale is not set at 15 kilograms, begin by placing weight equaling
your upper limit plus 0.8 kilograms.
Return to Zero Test
This test ensures that, after all other tests have been completed successfully, the scanner/scale
returns to zero. Without any weight on the weigh platter, verify that the scale reads 0.000
kg.
You have completed the calibration and verification process for weighing in kilograms.
If the scanner/scale passes all these tests:
1. Remove the weigh platter, inst
all the calibration switch cover and install a seal (if
required).
2. Reinstall the weigh platter.
If the scale fails any of these tests, turn to Section 4, Problem Isolation and follow the
troubleshooting procedures for Scale Failures.
