Once the Cal Reset is performed, the controller returns to the New Zero?
prompt. Press [SELECT] to toggle to the desired calibration routine.
Following a Cal Reset, a re-calibration should be performed before exiting
the calibration or Setup Modes. The reset will not be saved unless a re-
calibration is performed and changes are saved.

Known Load Cell is used to calibrate without test weights. The exact full
scale mV/V rating must be known for each load cell. All load cells must be
of the same full scale capacity. This procedure works best for hopper scales
where weight is evenly distributed and signal trimming is not required.
1. Access the calibration mode (see page 23).
2. Press [SELECT] to toggle to the Known LCOut routine.
3. Press [ENTER] at the Known LCOut prompt to display #of LC.
The number of load cells specified during the last calibration will also
be displayed. A value of zero (0) indicates that this calibration method
has not yet been performed.
4. Key in the number of load cells and press [ENTER]. For the Model
460, use the [PRINT] and [UNITS] keys to enter numeric values. Refer
to Table 2: 460 Key Functions on page 8.
- or -
Press [ENTER] to accept the displayed value.
5. The display prompts LC#x mVv (where ‘x’ is the load cell number) and
then shows the mV/V value (0.1 Æ 5.0) last entered for this load cell.
6. Key in the load cell’s mV/V value and press [ENTER]. For the Model
460, use the [PRINT] and [UNITS] keys to enter numeric values. Refer
to Table 2: 460 Key Functions on page 8.
- or -
Press [ENTER] to accept the displayed value.
7. Steps 5-6 will be repeated for as many load cells as specified in step 4.
8. The display prompts LC FS showing the value last entered for the load
cell full scale.
