Initial Calibration
When the scale is operated for the first time, a span calibration is recommended to ensure
accurate weighing results. Before performing the calibration, be sure to have the appropriate

unlocked position. See figure 5-1.
Or adjust the GEO setting according to your location (see table 4-2).

calibration. [ 0 kg ] will be displayed. Press Yes to accept. [--C--] will be displayed while zero
reading is stored. Next, the display shows the calibration weight value. Place the specified
calibration mass on the pan. Press Yes to accept the weight or No to select an alternate weight.
[--C--] will be displayed while the reading is stored. The display will show [done] if the calibration
