Chapter 6. Calibration
Manual
For manual calibration, you calculate and
input directly the slope and setting zero
points of the calibration line. There are three
reasons for doing a manual calibration
instead of an automatic calibration:
• You cannot move any material now, and
want to get started using your system with
a rough pre-calibration.
• You calibrated the system. Later, you
moved material into an empty vessel and
kept an accurate record of the actual
material weight (based on a truck weight or
some other accurate information) and the
indicated material weight (from the Weigh
II). However, you did not perform a calibra-
tion procedure at the time. You want to
use this information now to refine the
calibration.
• You want to re-enter data from a previous
calibration.
The calculation of the manual calibration
parameters for both a pre-calibration and for
calibration refining is covered in Appendix G,
Calculation of Manual Calibration Parameters.
Once you have calculated the parameters,
follow the procedure
below to perform a
manual calibration.
1. If the Weigh II is in Auto Mode (Auto LED
illuminated), press the Auto/Man Key to
put the system in Manual Mode. The Auto
LED turns off.
2. Use the Up Arrow and Down Arrow Keys to
scroll to the desired vessel.
3. Press the Menu Key to display the Main
Menu. The display shows:

6. Press the F1 Key to access ScfCnt . The
display looks like this:
7. Use the keypad or the Up and Down Arrow
Keys to input a value for the scale factor
counts. Press the Enter Key to save the
value in memory. The display flashes a
message acknowledging your entry and

8. Press the F3 Key to access ScfWgt . The
display looks like this:
The unit of measure you set up in the
Units Menu shows in place of lbs.
9. Use the keypad or the Up and Down Arrow
Keys to input a value for the scale factor
weight. Press the Enter Key to save the
value in memory. The display flashes a
message acknowledging your entry and
returns to:
10. Press the Menu Key to go to the
second page of the Manual Cal Menu. The
display shows:
