Cornerload Performance
1
Allow the balance to warm up sufficiently by
turning ON the power and leaving it at the
gramdisplay at least two hours before starting
the performance checks.
2
Move a weight that is approximately 1/4
th
of the
weighing capacity on the pan in the order
indicated by the numbers in the figure to the right
and record the value of each as X1 through X5.
If the difference between the readings at the
center position and each of the off-center
positions (eccentric error) is within five counts,
the balance cornerload performance is
considered normal.
3
If the differences (deviation error) between the
average value of the two values at the center and
the values for positions outside of the center are
all within five counts, the cornerload performance
is considered normal. One count refers to the
balance reading limit (1 scale).
The difference from the first center value can also
be used as the deviation error instead of the
average value of the two values at the center.
