6.9 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.
• In balances with a resolution of > 15 000 dividing steps carrying out a
linearisation is recommended.
• 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.
• After successful linearisation you will have to carry out calibration;
see chapter "testing instruments control".
• The adjustment is locked for verified balances. To disable the access
lock, destroy the seal and actuate the adjustment switch. Position of
the adjustment switch see chap. 6.11
