2 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 im-
prove this by means of linearization.
• Carrying out linearization is restricted to specialist staff possessing well
acquainted with the workings of weighing scales.
• The linearisation is locked for verified weighing systems.
In order to unlock the access, the seal must be destroyed and the
jumper on the printed circuit board must be fitted.
Attention:
After destruction of the seal the weighing system must be re-verified by
an authorised agency and a new verification wire/seal mark fitted before
it can be reused for applications subject to verification.
• The test weights to be used must be adapted to the weighing scale’s
specifications.
• Observe stable environmental conditions. Stabilisation requires a certain
warm-up time.
• After successful linearization you will have to carry out calibration; see
