Page 16: Adjustment
7.7 Adjustment As the acceleration value due to gravity is not the same at every location on earth, each display unit with connected weighing plate must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the weighing system has not already been adjusted to the location in the factory). - Page 17 For adjustment press to select setting < noLin> and confirm by Ensure that there are no objects on the weighing pan. Wait for stability display, then press The currently set adjustment weight will be displayed. Either apply the displayed adjustment weight or make changes with the help of the navigation keys (see chap.

Page 19: Linearization
7.8 Linearisation 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 monitoring of test resources, you can improve this by means of linearization. - Page 20 For linearization press to select setting < LinEr>, to confirm, press Ensure that there are no objects on the weighing pan. Wait for stability display, then press When “Ld 1“ is displayed, put the first adjustment weight (1/3 max) carefully in the centre of the weighing platform.

Page 29: Operation Modes
10 Operation Modes 10.1 Parts counting Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed by putting on a certain number of the parts to be counted. The balance determines the total weight and divides it by the number of parts, the so- called reference quantity. - Page 30 Automatic reference optimization • Menu setting: „P4 OTH“ „AVErG“ „on““, see chap. 11 In order to improve the counting exactness, the reference can be optimised by adding more pieces. At every reference optimisation, the reference weight is calculated anew. As the additional pieces increase the base for the calculation, the reference also becomes more exact.
