“STABLE” Indicator is illuminated.
2. Fill the cup with Grain.
3. When “STABLE” LED illuminates select the “lb/bu” switch to display grain in pounds per
bushel or “kg/hl” for kilograms per hectoliter.
NOTE 1: Grain Test can also be setup to use LITER and PINT cups. You must
change the Chr parameter to the proper setting for the correct result.
See Sections 5 and 6.
Theory of Operation:
The 9000AG grain scale can weigh a maximum of 2,000 grams. The resolution is 10000 divisions
which means the smallest increment is .2 grams. When calibrated the unit is accurate within +/- 2
divisions. The 9000AG has passed an extensive checklist of tests as prescribed in the HANDBOOK
44 document issued by the National Institute of Science and Technology. The 9000AG has passed
these tests to become NTEP (National Type Evaluation Program) certified.
The displayed resolution of the percentage, Lb/Bu and Kg/Hl are displayed to the nearest 1/100 (.01)
The 9000AG uses a linear power supply capable of input voltages from 104VAC to 127VAC. Nominal
AC voltage is 115VAC with .31 amps of current for 36 Watts.

Section 4
Parameter and Calibration mode Access (Setup mode)
The Model 9000AG parameters will change the operation of the scale. The parameters are accessed
either by removing the cover and selecting the CAL Switch located on the printed circuit board
mounted to the base of the scale. The other method is by holding down the PRINT and the hidden
switch located behind the Seedburo Logo.
The first parameter seen when in the Setup Mode is CAL 0. Please refer to Section 6 for using this
parameter. For now we will pass this parameter.
Selecting a Parameter:
The parameters are selected by pressing the gswitch to go forward in the list and the PRINT to go
backward in the list. A complete list of parameters can be seen on the following page.
Note: Think of the gswitch as a forward arrow or an Enter switch.
Changing a Parameter:
Each parameter has at least two different options that can be selected. To change a value for a
selected parameter you must:
1. Press the Zero switch. Each time pressed the display will change value. The display will
continue cycling through each parameter.
2. Once the selection is set to the desired value it will be saved temporarily by selecting the g
switch.
3. However it will not be saved permanently until you cycle through the parameters by using the
gswitch until the display reads SAVE.
4. Change the value to Yby pressing ZERO
5. Select gto save and exit the parameters.
Legal for trade mode:
The 9000AG scale can be configured to operate in USA and CANADA Legal for Trade Modes. This is
done by selecting the oP parameter and changing it from the default setting of STD to 44 or CAn.
Some parameters are disabled when in the Legal for Trade modes USA “44”and Canada “CAn”. All
parameters are available in the Operating mode of “Std”. The values that are disabled are marked
with an asterisk (*) in the Tables below. (in 44 mode AZt can be 0 or 0.5, mma is 1 and SUO ON)
The 9000AG comes set from the factory with the parameters marked in BOLD (see tables below).
You can default the parameters back to these setting anytime by selecting the dft parameter. Than
using the Zero switch to change the dft parameter from No to YES. Than select the gswitch to
default the scale.
NOTE: The parameter changes will be lost if you do not perform steps 3, 4 and 5 above.
Audit Counters:
When entering the Setup mode there will be displayed the audit counters. Each time a change is
made the counters will increment. There are two counters one will increment for each time a
parameter is changed the other will increment each time the scale completes a calibration.

Entering Calibrations and Parameter setup Mode:
The Calibration and Parameter Setup Mode can be entered by two different ways.
1) The Front Panel CAL Access Feature
To enter the calibration mode while the scale is powered up HOLD the hidden switch
behind the SEEDBURO Logo, now press the PRINT switch once.
At this point, the display will show the audit counters followed by the first menu parameter
CAL 0.
2) The CAL switch is a momentary push button located in the center of main Printed Circuit
board. The CAL switch can be accessed by removing the meter’s top cover.
After the push button has been pressed, the display will show the audit counters
followed by the first menu parameter CAL 0.
CALIBRATING THE 9000AG:
To calibrate your Seedburo Model 9000AG, you will need a set of precision test weights,
Class "Q" or better. This set consists of 2-2000g weights. Seedburo has these weight
sets available for purchase. Do not use test weights of lower accuracy than Class "Q" -
Scale calibration will not be correct, as it is dependent upon the accuracy of the test
weights used.
Before proceeding with calibration, be sure that the scale is level, stable, and away from
wind currents and vibration. Use the bubble level below the platter and the adjustable feet.
Note: Excessive vibration or wind currents can cause the count down cycle to
restart. This can cause errors in calibration. It is imperative that calibration
be done in an area free from vibration and wind currents.
1. Enter Calibration mode, wait until CAL 0 appears on the display.
2. Remove commodity holder or any weight from the scale platter and wait for about 10
seconds. Press ZERO and wait for the display to count down from 7 to 0. If the calibration
zero was in range, the display will return with CAL FS.
3. To complete the calibration process, place 2,000 grams weight on the platter and
press ZERO, wait for the display to count down to 0. If the span calibration was in
range, the display will return with weigh mode if successful.
4. If the display returns with a CAL 0, repeat
5. steps 2 and 3.
NOTE: If an error message appears Refer to the Troubleshooting section for additional information.

Section 7
Printer Modes:
The Model 8800SS offers four different print control modes. These modes dictate when
printer data is sent.
Transmit on demand (tod):
In this mode, scale data is transmitted whenever the PRINT button is pressed, or a print
request is received from the serial port. The scale must be stable and the scale value
must be valid before the data is printed.
Continuous print (CP):
In continuous print, data is transmitted each time the scale has a reading ready.
Readings which occur when the scale is in motion are called out by the abbreviation
"MOT." following the data.
Auto Print 1 (AP1):
Auto Print 1 transmits the first scale reading after the scale leaves motion. The reading
must be stable and must be a valid reading before it can be sent.
Auto Print 2 (AP2):
Like Auto Print 1, Auto Print 2 transmits the first scale reading following the scale
leaving motion. In Auto Print 2, no further readings will be sent until the scale returns to
displayed zero. The reading must be stable and must be a valid reading before it can be

Section 9
Troubleshooting:
Problem:
Check:
Will not power up. Blank screen.
Remove Power CORD from scale!
Remove the 6 screws holding the top enclosure to the base.
Check the Fuse located in the rear of the scale next to the
power switch. If blown replace with .25 amp time-delay fuse.
Next check if the display cable has become unplugged.
Sometimes if the scale is dropped or shipped a violent shock
may dis-lodge the connector from the printed circuit board.
Display stuck on LDG 0.
Zero is not stable
Remove all dead load from the scale (pans/seeds etc..) Make
sure platter is centered on the pins of the weighing
mechanism. Make sure there is not an excessive vibration on
the surface the scale is sitting on. Make sure scale is level.
Make sure the scale is not in direct line with a fan or vent
excessive wind could cause this message to appear.
If it is still in LDG 0 than you must enter the calibration menu
and re-calibrate the scale.
Display has 0 Undr
This means the scale is shifted in a negative direction. Add
dead load to scale. Make sure platter is centered on the
weighing mechanism Pins. If error continues, re-calibrate
the scale.
Display has 0 Ovr
Dead load exceeds 200 grams from zero point. Remove dead
load from scale(pan, grain, weights). If the error continues you
may have to re-calibrate the scale.
Display has udr Ld
This indicates the scale is in a severe under load condition.
Make sure platter is centered on the weighing mechanism
Pins. If error continues, re-calibrate the scale. If you cannot
calibrate replace load cell.
Display has Our Ld
The scale is 103% over initial zero or displayed zero,
whichever comes first. Remove weight from scale. If you
cannot get 2,000 grams to weigh without this meassage yo
must re-calibrate the scale. If you cannot calibrate replace
load cell.
Display Updating too slow
Try reducing filtering. Default is AVG 8. The smaller the
number the faster the update but the less stable the reading.
Scale is Unstable digits constantly
moving
Try Increasing AVG parameter to AVG 16. Shield scale from
wind currents. Place scale on solid table free from vibration.
Make sure scale is level.
