8. Click Next .
The Section Match Calibration Wizard displays all load cells installed on the system.

9. Place the test weight whose value you entered in step 5, on a section of the scale.
10. Click
Measure for the load cell pair corresponding to the section with weight on it.
Under Status, Success will display when measurement is finished. As each measurement is completed, the
next cell will become available to measure.
11. Repeat steps 9-10 until each section has been measured.
12. Click
Next .
13. If certified test weights are not being used, a span calibration must now be completed. If they were being used
(see Step 7), calibration was completed during normalization.
14. Add the test weight to the scale and click Calibrate Span .
15. If linear points were selected in Step 4, enter the applied weight in the text box and click Measure .
The Status will display Success when complete.
16. Click Next .
17. If chains or hooks are being used, remove them (along with all other weight) from the scale and click Re-Zero
Calibrate . Click Next .
18. Calibration is complete. Click Finish to commit the calibration values and send them to iQUBE 2 .
Click Cancel if you want to abort. This will require a re-calibration at a later time.
4.2.4 Theoretical Calibration
This option mathematically calibrates the scale using the full scale capacity and load cell sensitivities. Load cell
sensitivities can be specified using the procedure explained in Section 3.2.5 on page 27.
1. Click the Perform Theoretical Calibration button.
2. Click Calibrate .
3. If all load cell specific data (capacity and sensitivity) has been entered for the scale, click Yes .
4. Ensure there is no weight on the scale and click OK .
Theoretical calibration is complete.
4.2.5 Temporary Zero Calibration
This option uses the zero value from the last calibration and performs only a span calibration. Because the last cal-
ibration’s zero value is used, a previously calibrated scale is required. This calibration option could be used for a
tank that isn’t empty.
1. From the General tab, select Temporary Zero Calibration from the Calibration Type pull-down menu.
2. Click Calibrate .
The Temporary Zero Calibration wizard appears.
3. If linear points are being used, enter the applied weight in the text box and click Measure .
The Status will display Success when complete.
4. Click Next .
5. If chains or hooks are being used, remove them (along with all other weight) from the scale and click Re-Zero
Calibrate . Click Next .
6. Calibration is complete. Click Finish to commit the calibration values and send them to iQUBE 2 .
Click Cancel if you want to abort. This will require a re-calibration at a later time.
