Repeatability
Place the specified mass at the center of the pan and remove. Record the displayed values
with and without load. Repeat the test ten times (one set). Get 10 span data by subtracting
the displayed value when no load is applied from the displayed value when load is applied.
Obtain the standard deviation from the 10 data and verify that it is within the specifications. If
not, perform another two sets of test and obtain the standard deviation for each set. Verify
that the two standard deviations are within the specifications.
