%RANGE =
A.C. x L.C.
This would be equal to 13% for the example of a 100-lb
capacity load cell and a specimen area = 0.075 in
Hence, 10% is the highest % RANGE that could be used
for calibrating a recorder to Full Scale Stress.
Note
Do not use a full stress range that exceeds the
maximum allowable stress..
In some cases it may not be possible, and only part of
the recorder scale can be used without overloading the
cell. Under this condition, it is better to use a higher ca-
pacity cell.
