2 Calibration Procedure (CAL)

1. Turn balance on and allow the unit to acclimatize and stabilize for 2 hours.
2. Select the calibration weight according to the operating manual with [Print],
[Mode/Cal] and [Set/M] keys.
3. Press and hold the [Mode/Cal] key until the display shows a flashing weight reading.
The flashing weight reading indicates the correct weight that must be placed on the
weighing pan.
4. Gently place the correct calibration weight on the center on the weighing pan. With the
display still flashing, press the [Set/M] key.
5. The display will now show [Cal F] and then return to normal operating mode. The
calibration is complete when the display correctly shows the weight that is placed on
the weighing pan while the display has stabilized.
6. Remove the calibration weight and press the [TARE] key to reset the zero point.
In case [CAL E] is displayed instead of [CAL F], this indicates a calibration
procedure error. Turn the scale off and then on and repeat the procedure.
