EN-42 RANGER®7000 SCALES5.3.4 Linearity CalibrationLinearity calibration uses three calibration points, one at zero load and the others atspecified loads. Refer to Table 5.1 for Linearity values.TABLE 5-1 Calibration MassesModel Linearity Calibration Points Weight ClassR71MHD3 0 kg, 1.5 kg, 3 kg ASTM Class 2 OIML F1R71MHD6 0 kg, 3 kg, 6 kg ASTM Class 2 OIML F1R71MHD15 0 kg, 10 kg, 15 kg ASTM Class 2 OIML F1R71MHD35 0 kg, 20 kg, 35 kg ASTM Class 2 OIML F1R71MD3 0 kg, 1.5 kg, 3 kg ASTM Class 5 OIML M1R71MD6 0 kg, 3 kg, 6 kg ASTM Class 5 OIML M1R71MD15 0 kg, 10 kg, 15 kg ASTM Class 5 OIML M1R71MD35 0 kg, 20 kg, 35 kg ASTM Class 5 OIML M15.3.5 Internal Calibration (R71MHD models)Calibration is accomplished with the internal calibration mass. Internal calibration can be performed atany time, provided the scale has warmed up to operating temperature and is level.With the Scale turned ON and no load on the pan, select Internal Calibration.The Scale begins to calibrate.The display shows the status, then returns to the current application.To cancel at any time, press .5.3.6 Automatic Calibration (R71MHD models)When Automatic Calibration is set ON, the scale performs a self-calibration:• when it senses a temperature change of 1.5°C• or every 11 hoursAutoCal will automatically calibrate the Scale (using the internal mass) each time there is a change intemperature significant enough to affect accuracy.Note: * Automatic Calibration function is only available in certain regions.5.3.7 GEO AdjustmentEnter this sub-menu to set the GEO values.Press the button corresponding to the iconto adjust the GEO value.Choose the correct GEO value and press the buttoncorresponding to the icon to confirm.The values range from 0-31.Note: GEO is only available in R71MD models. See table 9-3 for GEO values.
