(This sampleillustrates a Span Calibration value based on a Full Scale Capacity and Calibration Unit settingof 30 kg.)If a different Span Calibration value is desired, enter the new value via the numeric keypad.(This sample illustrates a new Span Calibration value of 15 kg.)Note: Allowable range capacity 1 kilogram or 1 pound to 100% full scale are accepted,(whole numbers only). Note that values closer to the full span capacity will usually yield themost accurate calibration.Place the corresponding mass on the platform, then press the Yes button. -C- is momentarilydisplayed while the reading is stored.If calibration was successful, the calibration weight is displayed and the scale exitsautomatically to the active weighing mode. remove the weight and begin weighing operations.Remove the weight and begin weighing operations.4.1.2 Linearity CalibrationLinearity Calibration uses three points, zero, mid range and full scale. The mid range value can be optionally changed bythe user. Mid-range values closest to 1/2 full scale capacity are recommended to give the best performance over the entireweighing range. Before calibrating the scale, check that the weighing base is correctly leveled. When any selection withinthe Read-GMP menu is enabled, calibration results are automatically printed.With CAL displayed, press the Yes button. SPAN is displayed. Press the No button to skip andproceed to the next sub-menu item LIN.Press the Yes button to select and perform Linearity Calibration.The display flashes 0, indicating that nothing should be placed on the platform at this time.After ensuring that the scale platform is clear, press the Yes button. -C- is displayed while thezero point is established.After a few seconds, the requested mid-point calibration value and unit (based on the FullScale Capacity and Calibration Unit setting from the Setup Menu) flashes on the display. (Thissample illustrates a mid-point Linearity Calibration value of 30 kg, based on a Full ScaleCapacity and Calibration Unit setting of 30 kg.)If a different mid-point Linearity Calibration value is desired, enter the new value via thenumeric keypad. (This sample illustrates a new mid-point Linearity Calibration value of 20 kg.)Note: Allowable range is 25% to 75% full scale Capacity, (whole numbers only).Note that values closer to 1/2 full span capacity will usually yield accurate calibration.Place the corresponding mass on the scale platform, then press the YesYesYesYesYes button.-C- ismomentarily displayed while the reading is stored.
