Combine Calibration
1. Be sure crop type and combine setting are correct.
2. Turn off Variety Tracking. If it is on it will jump between tasks and
calibrations will not be accurate.
3. Go to the run screen with your Grower, Farm, Field, and Task.
4. Create a name for these if one has not previously been made.
5. When you get to the task hit edit name
6. Delete name and rename task to cal “low, med, or high” pending
on the flow you are doing at the moment. Name should look as so
cal high 1.
7. Now we will harvest around 5000lbs of grain at desired rate
stated in the task name. High is as fast as you will ever harvest,
low is coming in at a slow pace, and med is somewhere in
between. All tasks harvested for calibrations should be in similar
weight. This is why I choose 5000lbs because more weight cal take
a very long time in low flow.
8. Now that the desired amount of product is harvested go to run
screen with task and start a new task. This is a critical part
because if a new task is not started the calibration task will not be
in the calibrations menu.
9. From Run Screens hit the back button and go to the Calibrations
section.
10.
The next step is the same for moisture and yield.
11.
Hit moisture tab and fast, wizard, and advanced come up.
Go to advanced.
12.
Choose Grower, Farm, Field, Crop type, and Task that was
just completed.
13.
If you are doing this stem for moisture you will now see the
moisture for the task. If in yield cal you will see the weight
harvested for the task.
14.
Enter the actual moisture from the task and a % error will
come up and a cal task dropdown. Write down the task name and
% error for yield and moisture. Do not calibrate task at this time.
15.
Repeat steps 5 through 14 until you have 2 calibration loads
for each rate of harvest and have written down the percent error
for all of the tasks.
16.
Once all the tasks and errors are written down we will be
looking for a tight group of % error. Results may look as such.
Task name
Moisture % error
Yield % error
Cal low 1
3.1
4.6
Cal low 2
3.2
4.4
Cal .med 1
3.1
4.5
Cal med 2
3.0
6.1
Cal high 1
4.7
4.5
Cal high 2
3.2
4.4
What we are looking for in these % error are a grouping of similar error.
For moisture error our grouping would be 3.0 to 3.2. Most fall within
the group except cal high 1 at 4.7. Because it is not in the group we do
not want to use this in our calibration. We will only us 5 of the 6 tasks
for our moisture calibration.
For yield it is similar to the moisture in the fact that we have a good
grouping at 4.4 to 4.6 % error except for cal med 2 at 6.1. because it is
not in the grouping with the rest of the numbers we will not use it in
our calibration because it would throw off our accuracy.
17.
Once we have decided what tasks are within our acceptable
error we can now go to the calibrations and advanced. For both
moisture and yield choose the grower, farm, field, and task. In the
dropdown for Cal task change to yes for all acceptable cal tasks.
Do not change for the tasks that are not within the grouping.
18.
Once all acceptable tasks are changed to yes on cal tasks we
need to run a test load to be sure we now have an acceptable
final % of error.
If you have any question on calibrating your combine or would
like assistance on calibrating. Beard implement has a flat fee for
calibrating combine per crop.
