13.4 Default adjustment parameter P 0.9 CALThe parameters P0.0 to P0.7 are preset by the connected weighing cell and need tobe entered accordingly.Adjustment is to be carried out by applying the weight value that is set for parameterP0.7 wEi. In doing this, ensure that this value for adjustment is as closely as possibleto the maximum load of the weighing cell, that is, between 80 and 100% of themaximum load. The accuracy of the adjustment weight must correspondapproximately to or, if possible, be better than, the readability of the balance (displayunit in combination with weighing cell). Weights of different nominal values may beused for calibration but are not optimal for technical measuring.Sequence of operations for adjustment:Unload weighing plate, select parameter 0.9 CAL.Adjustment is activated by pressing the TARE key, followed by noCal appearing onthe display. The display unit with the weighing cell connected carries out adjustmentfor the zero point.Once this is completed, LoAD will appear on the display, followed by the weightvalue of the adjustment weight (value of P 0.7 wEi).Place the adjustment weight on the weighing plate and press the PRINT key.During calibration CAL will appear on the display, followed by unLoAD.Remove the adjustment weight and donE will appear on the display.Afterwards 0.9 CAL will be shown and you can edit additional parameters.Parameter 0.8 St_u allows you to set the initial weight.13.4.1 Linearization Parameter P 0.L LinEAn existing non-linearity can be corrected with the help of this parameter.For this purpose can be defined up to 6 linearization points. In order to do that, theparameter 0.L LinE must be selected after the factory adjustment (chap. 13.4) andthe weighing plate unloaded.After having pressed the TARE-button, the function is activated and „Pnt1“ appearson the display (first linearization point).When pressing the PRINT button, „0“00.000 kg appears on the display.The first number flashes and with the help of the TARE and a-buttons therespective position and the value can be selected, the first linearization point is takenover using the PRINT button.KLB-TM-BA-e-0811 51
