Calibration Verification (Kilograms)Product Reference Guide 91Decreasing-Load TestThis test ensures that the scanner/scale responds properly when a heavy objectis followed by a significantly smaller object.Return to Zero TestThis test ensures that, after all other tests have been completed successfully,the scanner/scale returns to zero. Without any weight on the weigh platter, ver-ify that the scale reads 0.000 kg.You have completed the calibration and verification process for weighing inkilograms.If the scanner/scale passes all these tests:1. Remove the weigh platter, install the calibration switch cover and install aseal (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.NOTEIf the upper weight limit for your scale is not set at 15 kilograms, begin by placingweight equaling your upper limit plus 0.8 kilograms.SINGLE INTERVAL DUAL INTERVAL1. Place weights that total 15.8 kilograms. 1. Place weights that total 15.8 kilograms.2. Remove weights to leave 10 kilogramson the scale and verify that the displayshows between 9.995 and 10.005 kilo-grams.2. Remove weights to leave 10 kilograms onthe scale and verify that the display showsbetween 9.995 and 10.005 kilograms.3. Remove an additional 9.00 kilogramsfrom the scale and check that the scalereads 1.000 kg.3. Remove an additional 4 kilograms from thescale and check that the scale readsbetween 5.998 and 6.005 kg.4. You have completed the DecreasingLoad Test.4. Remove an additional 2 kilograms from thescale and check that the scale readsbetween 3.998 and 4.002 kg.5. Remove an additional 3 kilograms from thescale and check that the scale reads 1 kg.6. You have completed the Decreasing LoadTest.
