6.8 LinearizationLinearity shows the greatest deviation of a weight display on the scale to the value ofthe respective test weight according to plus and minus over the entire weighingrange.If linearity deviation is discovered during a testing instrument control, you canimprove this by means of linearization.Carrying out linearization is restricted to specialist staff possessing wellacquainted 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 thejumper on the printed circuit board must be fitted (see chap. 6.9).Attention:After destruction of the seal the weighing system must be re-verified byan authorised agency and a new verification wire/seal mark fitted beforeit can be reused for applications subject to verification.The test weights to be used must be adapted to the weighing scale’sspecifications; see chapter 3.4 “testing instruments control”.Observe stable environmental conditions. Stabilisation requires acertain warm-up time.After successful linearization you will have to carry out calibration; seechapter “testing instruments control”Procedure: Call-up menu setting , see chap. 6.7.  Acknowledge with .Ensure that there are no objects on the weighing plate. Wait for stability display „STABLE“, then press . When“LoAd 1“ is displayed, put the first adjustment weight (1/3max) carefully in the centre of the weighing platform. Wait for stability display „STABLE“, then press .
