CDE/CME/CDEE-BA-e-1014146.7 AdjustmentAs the acceleration value due to gravity is not the same at every location on earth,each balance must be coordinated - in compliance with the underlying physicalweighing principle - to the existing acceleration due to gravity at its place of location(only if the balance has not already been adjusted to the location in the factory). Thisadjustment process must be carried out during the initial start-up, after change inlocation and variation of surrounding temperature. To receive accurate measuringvalues it is also recommended to adjust the balance periodically in weighingoperation.6.8 AdjustmentThe adjustment should be made with the recommended adjustment weight (seechap. 1 "Technical data"). Adjustment is also possible with the weights of othernominal values (see table 1, chap. 8.4.4), but not the optimum for measuringtechnique.Procedure when adjusting:Observe stable environmental conditions. A warming up time (see chapter 1) isrequired for stabilization.Ö Turn on balance by pressing the ON/OFF keyÖ Press and keep holding down the key. In addition press the ON/OFF-keyat the same time. Keep pressing both keys for 3 s until the display isextinguished.Ö Let go of both keys. “CAL“ appears. After that the exact size appears flashingin the display (chapter 8.4.4) of the adjustment weight. Now set the adjustingweight in the centre of the weighing plate.Ö Confirm by pressing the PRINT key Short time later appears „CAL F“, thenreturn automatically to the normal weighing mode. In the display thereappears the value of the adjustment weight.Ö An error during adjustment or the use of an incorrect adjusting weight willresult in an error message „CAL E“. Repeat adjustment.Keep the adjustment close to the balance. Daily control of the weighing exactness isrecommended for quality-relevant applications.
