Decreasing Load Test
The Decreasing Load Test checks the scale accuracy when incrementally removing weight from the Top Plate. Use weights that correspond to the NCR 7895 programmed unit of weight.
Note
This test must immediately follow the Over-Capacity Test. Do NOT remove any of the weights from the previous test prior to running this test.
