Linearity and Hysteresis check
Calibrate by using the calibration mass in table below.
After calibration, in the D2 data mode, place the specified check mass in the table below one
by one on the pan, and check that the difference between the true value and the displayed
value is within the specifications (linearity). After reaching the weighing capacity, remove
each mass one by one, and check that the difference between increasing points and
decreasing points are within the specifications (
hysteresis) .
