Decreasing-Load Test
This test ensures that the scanner/scale responds properly when a heavy object
is followed by a significantly smaller object.
Return to Zero Test
This test ensures that, after all other tests have been completed successfully,
the scanner/scale returns to zero. Remove all weights from the scale and verify
that the scale reads 0.00 lb.
After completing this test, close the calibration access cover and seal per local
Weights and Measures requirements. This final step must agree with the legal
requirements of your state or local government.
You have completed the calibration and verification process for weighing in
pounds.
If the scanner/scale passes all these tests:
1. Remove the weigh platter, install 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 5, Problem Isolation and fol-
low the troubleshooting procedures for Scale Failures.
NOTE
If the upper weight limit for your scale is set to other than 30
pounds, begin by placing weight equaling your upper limit set
