2. Press ‘8’ then ‘ENT’.
3. Enter ‘93010001’. The raw value for cell #1 will be displayed in
decimal and hexadecimal (the 2 leading digits of the hexadecimal
value are status flags). Verify that the correct cell is selected by
applying a load to the cell and observing the change in the display.
Remove any load from the display and prepare to place calibration
weight on the cell.
4. Enter ‘93010004’. This instructs the controller that the cell is without
the calibration weight.
5. Place the calibration weight on the cell. It is important that the weight
acts only on the cell.
6. Enter ‘93010005’. This instructs the controller that the weight is now
on the cell. The controller will prompt for the value of the weight in
units of 1/100 kg (i.e. 40kg = 4000).
7. Enter the weight value. The controller will calculate the calibration
values and return to displaying calibrated weight. Note that at this
point the new calibration values are not saved and the zero point has
not been set.
8. Repeat steps 1 to 5 for all cells. If a cell is not connected then repeat
the process except for step 3 and enter ‘0’ for the weight value.
9. Remove all calibration weights and restore the weigh scale platform.
Enter ‘93010007’. This will set the zero point. Verify that the
calibration is correct by placing test weights in various locations.
10. Enter ‘93010006’. This will save the calibration values.
5.2 SETTING THE NODE NUMBER
In order for the scales to communicate with the rest of the NOMAD system a
number must be assigned to the scales to identify it from other items in the
system.
1. Ensure the scales are in supervisor mode.
2. Press ‘8’ then ‘ENT’.
