6.6 Linearization
Linearity shows the greatest deviation of a weight display on the scale to the value of
the respective test weight according to plus and minus over the entire weighing
range. If linearity deviation is discovered during a testing instrument control, you can
improve this by means of linearization.
• Carrying out linearization is restricted to specialist staff possessing
well acquainted with the workings of weighing scales.
• The test weights to be used must be adapted to the weighing scale’s
specifications; see chapter “testing instruments control”.
• Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
• Do not remove the adjustment weight during linearization in step
LAOD 1
to LOAD 4, merely increase it instead. Conversely do not
remove the adjustment weight during step LAOD 4 to LOAD 1,
merely increase it instead.
• After successful linearisation you will have to carry out calibration;
see chapter “testing instruments control”.
