Introduction

Monitor Organization

The yield monitor is designed to accurately measure and record acres, moisture, grain weight, bushels, and yield in bu/ac on-the-go. It is GPS compatible and can log yield mapping data on memory cards. The yield monitor must be calibrated to be accurate.

If you are using the monitor with a GPS receiver, you must use a memory card to save GPS information. If you do not have a GPS

receiver, you do not need a memory card; the monitor has enough internal memory for 976 total loads and 255 total fields which should last the entire season.

The monitor is organized by fields and loads. A load subdivides a field into smaller sections. A monitor load can be smaller or larger than a combine tank, wagon, or truck load. It is recommended to use different loads for different hybrids or varieties or field conditions (like a wet hole). The operator manually changes the load when it is appropriate to do so while harvesting.

Keypad

The monitor has three groups of keys: a top group, a bottom-left group, and a bottom-right group. When you press a key, the monitor beeps. Each key (particularly the SETUP and MEM keys) have menu items to scroll through by continually pressing the key to advance to the next menu item under that key.

Grain Flow Sensor

Below is an example of a grain flow sensor. Your grain flow sensor may look different, depending on which combine model you have. On all combines, the grain flow sensor installs on top of the clean grain elevator. The grain flow sensor measures the grain weight in pounds as you harvest. The clean grain paddles throw the grain, as the paddles rotate around the top sprocket, toward the grain flow sensor. The flow sensor measures the grain weight when the grain strikes the flow sensor impact plate.

Before Setup

Using Power Supply

Setting the Monitor on Field, Load

Other than for setting the stop height and calibrating the distance, the yield monitor console does not need to be in the combine to set it up. You can use the provided power supply (plugs into 120 v outlet) to power up the monitor console inside your home or shop.

When going through the setup procedures, take note of which settings can be set differently for each load. You should setup the monitor with it set to Field 1, Load 1, because any new loads you create will use the settings for the previously created load in that field. The monitor should come from the factory with only Field 1, Load 1 created. Follow the procedure below to try to change to a different field and load to verify that only Field 1, Load 1 has been created. If there is more than one field and load already created in the monitor, you will have to change the settings for each one of those loads.

Step Action

1 Press the FIELD key to display the field only to find the last field

and created.

2 Press the top UP ARROW key until “START NEW FIELD?”

appears on the display.

Note: You can see how many fields are already created by scrolling through the fields until START NEW FIELD? is displayed.

3 Press the NO key.

Step Action

4 Press the LOAD key to display the field and load. 5 Press the top UP ARROW key until “START NEW LOAD?”

appears on the display.

Note: You can see how many loads are already created by scrolling through the loads until START NEW LOAD? is displayed.

Logging Settings

Selecting a Logging Device

The instantaneous yield and GPS data are not recorded in the monitor’s internal memory, but are logged to a separate device; either a memory card or an external datalogger, which connects to the nine-pin serial port on the monitor.

To select a logging device, press the SETUP key until “LOGGING DEVICE =NONE or ?M CARD or EXT” appears on the display. Use the top UP or DOWN ARROW keys to select the correct setting from the menu choices:

• NONE: Select this setting if you do not have a GPS receiver and

therefore are not logging instantaneous yield and GPS information on either a memory card or a datalogger.

• ?M CARD: Select this setting if you have a GPS receiver and will be

logging instantaneous yield and GPS information to a memory card in the yield monitor. The ? changes to the size of the card that was last formatted in the monitor.

• EXT: Select this setting if you have a GPS receiver and will be logging

instantaneous yield and GPS information to an external datalogger.

Notes:

• The monitor will not log to a memory card and datalogger at the same

time.

• The LOGGING DEVICE must be set on ?M CARD for the monitor to

receive a GPS signal.

• When the monitor is turned on with the logging device set for a card, the

monitor beeps and asks you to “INSTALL CARD OR PRESS NO” before it advances to the normal operating mode. Press the NO key if you do not have a card and want to advance to the next operating mode.

Scale Factor Press the SETUP key until “SCALE FACTOR=x.x” is displayed.

Press the top Up and DOWN ARROW key to change the scale factor to the value on the Initial Calibration Sheet.

Important:

• Never change the scale factor during harvest. Doing so will cause the

monitor to lose calibration accuracy and you will have to set the monitor on different grain types and recalibrate every grain type.

• If you have cleared the fields in the monitor, but have a good

calibration and will save the old calibration loads, do not adjust the scale factor number, even if it is not set to the value on the initial calibration sheet. If you do adjust the scale factor after saving the old

calibration loads, you will have to erase the old calibration loads and enter new calibration loads for every grain type.

Setting Swath

Follow these procedures to set the swath.

Note: The number of rows and row space needs to be set for each grain type. The monitor calculates swath by multiplying the number of rows by row space.

Step Action

1 Press the GRAIN key and use the bottom-left UP or DOWN

ARROW keys to change to the grain type of which you want to set the swath.

Note: You must have a load displayed to change the grain type.

2 Press the # ROWS key to display “x ROW CUT, x ROW HEAD”

for the selected grain type.

3 Use the RIGHT or LEFT ARROW keys to move the cursor under

the “Row Head” value. Use the top UP or DOWN ARROW keys to set the Row Head value to the correct number of rows for the selected grain type.

Note: The Row Head value is the permanent number of rows; do not change it after it is set. The Row Cut value is used to calculate acres, and it can be used to reduce the number of rows in partial swath situations (point rows). Whenever you change the value for the Row Head, the value for the Row Cut automatically adjusts to equal the Row Head value.

4 Press the ROW SPACE key to display “x INCH ROWS” for the

selected grain type, then use the top UP or DOWN ARROW keys to set the correct value.

Setting Swath

Yield Monitor 2000

Ag Leader Technology

Step Action

5 Repeat the above steps for each grain type that will be harvested.

Make sure to set the grain type back to the original setting for the load after you have finished setting the swath.

Recommendations for Row Crop Heads:

• For row crops, set your row space to the planted row spacing

and your number of rows to the number of total rows of your combine head.

Recommendations for Cutting Platform Heads:

• Set the swath in the monitor to one foot less than the actual

swath width of the head because you can rarely maintain a constant full swath while harvesting.

• Set the monitor on a row space of 12 inches and a number of

rows that adds up to the correct swath.

Example: If your cutting platform head is 20 actual feet, set the monitor’s swath to 19 feet by setting the row space to 12 inches and the number of rows to 19. Setting the row space to 12 inches for cutting platforms allows you to reduce the cutting swath by easierto-see one-foot increments when you are harvesting a partial swath.

Refer to the Swath Setting document in the operation section for more information about partial swath.

You have to calibrate distance for wheels, tracks, or radar speed settings, depending on which one you use. Refer to the calibrating distance instructions in the Calibration section.

If you are getting your ground speed from a GPS receiver, you probably will have to change a setting on the GPS receiver to “turn on” the ground speed feature. Even using a GPS receiver for ground speed,

you still must select either wheels, tracks, or radar as a backup speed sensor and calibrate distance for that setting. If the GPS signal is lost, the monitor will take readings from the backup speed sensor.

for that load. Press the MOIST key until “xx.x AVG %” appears on the display.

5 Use the bottom-left UP or DOWN ARROW keys to set an average

moisture value for that load.

Buildup on the Sensor

The moisture sensor can give readings that are too high if sticky material from weeds or green stems buildup on the moisture sensor. This is normally only a problem in soybeans with a lot of weeds or green stems. If you have high moisture readings from buildup, remove the moisture sensor and clean it. After cleaning, continue harvesting. If the buildup condition is severe, you may not be able to keep the moisture sensor clean. In such conditions, set the moisture for the load on manual and enter the average moisture for that load as instructed above. After buildup conditions cease, set the moisture back to automatic.

Starting, Naming Fields, Loads

Recommendations

Starting, Naming Fields and Loads

Follow these guidelines when starting and naming the fields and loads:

• It is strongly recommended that you create and name the fields and loads

before harvest because this will save you time during harvest.

• Select field names that you can use year after year; do not try to use the

field numbers of the monitor to keep track of the fields from year to year. The monitor’s data recording system works best if you select a name for a field and reuse the same name in successive years for that field’s yield data.

There are two ways to start and name your fields and loads:

• Connect the monitor to a computer that runs Windows 3.1 or Windows 95

• Start and name fields and loads on the monitor

Note: You may want to start and name the fields only because you may not know how many loads you want to create until harvest. You can always create and name fields and loads or change field and load names on the monitor during harvest.

Starting, Naming Fields and Loads With a Computer

To create and name the fields and loads with a computer, you must first connect the yield monitor to the computer and establish communication. Refer to the “Connecting the Monitor to Your PC” instructions in the Printing Field/Load Summary document in the Operation section for information about establishing communication between your computer and yield monitor. If you have Windows 95 you will use the HyperTerminal program. If you have Windows 3.1 you will use the Terminal program.

After you have established communication, “Type PRINT, NAME, or START & press Enter” will appear on the computer display, and the monitor will be set to READY TO PRINT.

You must enter commands on the computer to start and name fields and loads and to select a grain type. When you enter a command on the computer, the display on the monitor will change accordingly. After you enter a command on the computer, “Type PRINT, NAME, or START & press Enter” is displayed again on the computer indicating you can enter another command. Refer to the commands and instructions below.

• OPT GRAIN 1

Note: You can only have one grain type per field. When you set the grain type for the field, the monitor is actually setting the grain type for the load (will be load one if no loads have been created yet). When you create more loads in that field, the grain type of the new loads will be the same as the grain type of the previous load. If loads have already been created in the field, and you are setting the grain type with the field only displayed, you actually will be setting the grain type for only load one in the field. You will have to display each load previously created in the field and change the grain type for each load.

To name the field, type name and press the Enter key and then enter a name up to eight characters long at the “New Name:” prompt on the computer screen. Press the Enter key to accept the new name.

Note: Choose a name for each field that you will use year after year for that field.

5 Repeat steps 1-4 and create and name all your fields. 6 Once you have named all of the fields, set the monitor on the first

field by pressing the F key and then the D key on the computer to scroll to the very first field.

Follow these steps to create and name fields with the monitor:

Step Action

1 Press the FIELD key to display field only on the top line. 2 Use the RIGHT ARROW key to move the cursor (the line under the

arrow or colon just to the right of the field number) to the right one or more spaces.

3 Press the top UP or DOWN ARROW key scroll through symbols,

numbers, or letters you can use to name the field. Move the cursor to the right one space to enter another character. You can enter up to eight characters for a name. To remove a character, scroll to the space located between the 9 and A.

Example:

F1:WEST8 CORN 0.0 AV B/A

Note:

• The monitor beeps each time the character changes. If you hold

down the top UP or DOWN ARROW key, you will notice that the characters change slowly for the first few, but then begin changing very rapidly. This allows you to easily make a change of one or two characters while allowing you to scroll through all the available characters rapidly.

• Choose a name for each field that you will use year after year for

that field.

4 Press the top UP ARROW key to try to advance to the next field. If

the next field has not been created, the top line displays “START NEW FIELD?”

5 Press the YES key to start a new field. The monitor beeps four times

quickly, displays the field number and “SET GRAIN/PRESS YES” on the top line, and displays the grain type set for the previous field on the bottom left.

6 If the grain type displayed is not correct for this field, use the

bottom-left UP or DOWN ARROW keys to change it. 7 When the grain type is set correctly, press the YES key. 8 Name the field and repeat steps 1 through 7 for each field you want

to create.

When you have created all the fields you need, scroll back to the first field that you expect to harvest.

Starting, Naming Loads With the Monitor

The next step is to create and name the loads within the fields. You need to consider how you want to logically subdivide the fields into loads.

Note: It is common to designate Load 1 for the end rows and name it “ENDROWS”. The other loads could be designated for a certain variety or hybrid. Name these loads the hybrid or variety name (example: “L2:P3417”). Because you may not know how many loads you want to create until harvest, you can create and name more loads any time.

Step Action

1 Press the LOAD key to display field and load on the top line. 2 With the cursor under the load, use the RIGHT ARROW key to

move the cursor to the right one space.

3 Press the top-right UP ARROW key to change the blank space to

either a symbol, number, or letter. You can enter up to eight characters for a load name.

Example:

F1:WEST8 L1:HYBRID CORN 0.0 AV B/A

4 Press the LOAD key to display field and load on the top line to

create a load.

5 Press the top-right UP ARROW key to scroll to the next load. If

the next load has not already been created, the monitor displays

“START NEW LOAD?” on the top line. 6 Press the YES key to start a new load. 7 Name the new load and create and name loads for all the fields you

have created. 8 Repeat steps 1 through 7 for each field you want to create.

Setting Stop Height

Setting Area Count Stop Height

The monitor automatically takes readings from the header sensor so that when you lift the combine’s head at the end of the rows to turn around, and stops counting area if the head is raised high enough. The stop height number setting determines how high the head must be raised at the ends of the rows to stop counting area. The stop height can be set differently for each grain type.

Follow these procedures to set the stop height:

Step Action

1 Set the monitor on a data load (load with an arrow to the right of the

load number (L1->).

2 Press the GRAIN key to display the grain type. Use the bottom-left

UP or DOWN ARROW keys to change the grain type.

Note: You must have a load displayed to change the grain type.

3 Press the STOP HEIGHT key to display the stop height value

(typically, the value is between 55 and 75).

4 Position the head at the height at which you want to stop counting

acres (this must be slightly higher than the height at which you run the head while harvesting).

5 Put the area count switch in the up position. If the AREA COUNT

LIGHT is off, use the top DOWN ARROW key to decrease the stop height value until the light turns on.

Note: When the light is off, you are counting acres. When it is on, you are not counting acres.

6 If the AREA COUNT LIGHT is on, use the top UP ARROW key to

increase the stop height value until the light turns off. Then decrease the value by one, which should make the light turn on.

7 Change the grain type to a different grain and set the stop height

value for that grain type.

8 Repeat steps 1 through 7 for all grain types you will harvest. Make

sure you change the grain type for the load back to its original setting.

Note: You may want to fine-tune the stop height when you begin harvesting.

Calibrating Distance

Yield Monitor 2000

Ag Leader Technology

Preparing to Calibrate Distance

You must do the following before you begin calibrating distance:

• Accurately measure a known distance, setting flags or making a mark at

each end

Notes:

• A distance of at least 200 feet is desired to obtain an accurate

calibration.

• For maximum accuracy, calibrate on a ground surface that is at least

somewhat similar to field conditions (you can also calibrate while harvesting if you know or measure a precise distance in the field).

• Change to a data load (load with arrow to right of load number L1->)

with no distance.

Follow these procedures to change to a data load.:

Step Action

• Start a new load by pressing the top UP ARROW key with the

load displayed and scroll past the last load.

• Make an existing load the data load by pressing the MEM key

until “CHANGE TO THIS LOAD?” appears on the display, then press the YES key.

2 Press the DIST key to display “x FT,” and check that 0 feet are in the

data load. If there are feet in the load, start a new load according to step 1.

Calibrating Distance

Follow these procedures to calibrate the monitor for distance:

Step Action

1 Press the DIST key until “SPD=WHL or TRK or RAD or

GPS/WHL or GPS/TRK or GPS/RAD” is displayed. Use the lower right UP or DOWN ARROW keys to change “SPD=” to:

WHL if you are using the wheel speed sensor on the combine for

ground speed

TRK if you are using the track speed sensor on the combine for

ground speed

RAD if you are using a radar gun for ground speed

Note:

If you are using a GPS receiver for ground speed (monitor set on SPD=GPS/WHL, GPS/TRK or GPS/RAD) you still need to set speed equal to either WHL, TRK or RAD and do a distance calibration for the backup speed sensor. The monitor will start using the selected backup speed sensor if the GPS signal is lost.

Do not set “SPD=” to anyone of the three GPS settings when calibrating distance.

Example:

If you are using your GPS receiver as the ground speed sensor and you are using the wheel speed sensor on the combine as the backup speed sensor, you must calibrate distance for the wheel speed sensor by setting SPD=WHL. However, the speed setting you should leave the monitor set on for field operation is SPD=GPS/WHL.

2 With the AREA COUNT SWITCH down and the red light on

(distance and area counting stopped), pick a spot on the combine and align it with the marking at one end of the measured distance.

3 Flip the AREA COUNT SWITCH up, and, if necessary, lower the

head enough to make the red light turn off. 4 Press the DIST key until “x FT” is displayed. 5 Drive the measured distance, stopping at the end mark. 6 Flip the AREA COUNT SWITCH down (red light turns on).

7 Use the lower-right UP or DOWN ARROW key to increase or

decrease the number of feet displayed so that it is equal to the distance measured.

Notes:

• When you change the feet measurement on the display, you are

changing the distance calibration number. You can see the

number if you press the DIST key until “xxxxpls/100’ “ appears

on the display.

• It may take several increment or decrement cycles to go from

where the measured distance is 1 foot under to 1 foot over the

measured distance. Count the number of beeps and set it in the

middle of this range.

Clearing Feet Out of the Load

Calibrating Distance Accurately

Follow these procedures to clear the feet out of the load:

Step Action

1 Press the MEM key until “CLEAR DATA IN THIS LOAD?”

appears on the display. 2 Press the YES key. 3 After the Monitor beeps four times and “ARE YOU REALLY

SURE? YOU WILL LOSE DATA” appears on the display, press

the YES key again. 4 If you are using a GPS receiver for ground speed, change the

“SPD=” setting back to the correct GPS setting for that load.

Turn the combine around and repeat the above steps for calibrating distance and clearing feet out of the load until you are confident that you have set the distance calibration as accurately as you can.

Note: Perform this check while traveling forward only because combine tires roll slightly differently in forward than they do in reverse.

Calibrating Temperature

Introduction

Calibrating Temperature

The moisture sensor contains a temperature sensor, which measures the grain temperature for use in adjusting the measured grain moisture.

Follow these procedures to calibrate temperature:

Step Action

1 Press the MOIST key until the temperature reading “xx DEG F”

appears at the bottom-left of the display.

2 Use the bottom-left UP or DOWN ARROW keys to set the

temperature to the ambient air temperature, which automatically changes “x T OFFSET”. (You can press the MOIST key to display “x T OFFSET”).

Notes:

• For accurate moisture readings, it is more important that you not change

the temperature offset while harvesting than it is to have it set exactly right. Therefore, after you set it, leave it at that setting.

• To calibrate temperature accurately, you must obtain an accurate

ambient air temperature after the temperature has been relatively stable for several hours.

• If the combine has sat overnight, the moisture sensor may be cooler than

ambient air temperature because the air can warm much more quickly than the sheet metal of the combine. If you are adjusting temperature without harvesting grain, it is best to do it when the combine has been sitting in a constant ambient temperature for several hours.

• If you set temperature while harvesting grain, the sensor measures grain

temperature, which will be close to ambient if the air temperature has been constant for several hours.

• To get the most accurate setting, check grain temperature at the combine

with a thermometer.

Introduction

Calibration Procedure

The yield monitor must be calibrated to eliminate false grain flow readings that are caused by vibration forces when the combine runs empty. Press the GRAIN key to set the C1 number to eliminate the false grain flow readings. C1 must be set for each grain type you harvest.

Follow these procedures to calibrate for vibration (C1):

Step Action

1 Set the monitor on a data load (load with an arrow to the right of the

load number, L1->) that has no data in it and is set for the correct grain type.

Note: To set the monitor on a data load, follow these steps:

Step Action

1 Either start a new load or display a load that was already

created.

2 Press the MEM key until “CHANGE TO THIS LOAD?”

appears on the display.

3 Press the YES key. 2 Press the GRAIN key until “C1=x” appears on the display. 3 Use the bottom-left DOWN ARROW key to set C1=0. 4 Press the FLOW key to display “x BU/HR”. 5 Engage the separator and run the combine empty and at full throttle

and watch the flow in bu/hr.

6 With the separator running, increase the C1 number using the

bottom-left UP or DOWN ARROW keys until the flow in bu/hr is reduced to a zero reading. Because the vibration forces are not constant, it may be hard to adjust C1 so that there is always a zero flow. You should adjust C1 high enough, so that there is only one flow reading over zero in a 10 second period.

3-6

Note:

• You should have the head on the combine when you perform

steps 5 and 6. A head adds to the combine vibration, particularly cutting platform heads.

• The final C1 value should be between 0 and 250.

Calibrating Moisture

Yield Monitor 2000

Ag Leader Technology

Important Notes

Grain Moisture Calibration Procedure

• You must calibrate the monitor for grain moisture for each grain type

before the monitor can accurately measure grain moisture and dry bushels. Moisture is calibrated on one load only.

• Make sure the temperature has been properly calibrated before

calibrating moisture. Refer to the instructions in this section for calibrating temperature.

• You do not have to calibrate for grain moisture at the beginning of the

season to get accurate results, although it is recommended. You can wait for a more convenient time in the season to calibrate moisture. The monitor will automatically correct all grain moistures for all the loads that were previously harvested of that grain type.

Follow these procedures to calibrate the monitor for grain moisture:

Step Action

1 Set the monitor on a data load (arrow to the right of load number,

i.e., L1à) of the correct grain type that has no data in it, and harvest a load of grain into the monitor. Ideally, the load should be only one to two combine hoppers of grain that varies little in moisture content. Calibrating moisture using a smaller load will make it less likely for the moisture to vary within the load which will give a more accurate calibration.

3-8

Notes:

• To set the monitor on a data load:

• Either start a new load

-or-

• Display a load already created.

• Press the MEM key.

• Press the YES key when the message “CHANGE TO

THIS LOAD?” appears at the bottom of the display.

• Press the MOIST key to check that the data load the monitor is

set on is set to MOIST=AUTO”.

2 Use a reference moisture sensor and take readings from several grain

samples from that load.

Caution: Do NOT enter the grain tank when the separator is running.

Buildup on the Moisture Sensor that cause high readings

Note: When you change the displayed moisture with the arrow keys,

the monitor automatically changes the “x.x% OFFSET” value under the MOIST key and vice versachanging the offset value automatically changes the displayed moisture readings. Typical offset values are 0.0corn, +2.0wheat, +4.5soybeans.

Make sure the moisture sensor does not have a buildup of sticky material on it (this can be a problem with soybeans) when you are harvesting the moisture calibration load. You will know there is buildup if your moisture is reading 8-10 or more percentage points too high. If you calibrate moisture when the moisture sensor has a sticky buildup, your calibration will be inaccurate.

If you have a severe buildup problem on the moisture sensor, follow these procedures to set those loads to manual moisture. Refer to the Operation section for more details.

Calibrating Grain Weight

Before You Begin

Calibrate the moisture before calibrating grain weight. Refer to the

instructions in this section for moisture calibration.

You must calibrate the monitor for grain weight (lbs) for each grain type before the monitor will accurately measure bushels. You should be able to calibrate your yield monitor for grain weight to an average error of 1 percent to 3 percent.

IMPORTANT: Before calibrating, it is extremely important that you check the clearance between the tip of the clean grain elevator paddles and the inside of the elevator housing at the top of the clean grain elevator. There must be ½ inch or less clearance as the paddle rotates around the top sprocket. If your clearance is more than ½ inch, your

calibration will likely be inaccurate.

You do not have to calibrate grain weight at the beginning of the season to get accurate results, although it is recommended. Each time you calibrate the monitor, it will automatically correct all grain weights for all the loads of that grain type that were previously harvested.

Note: Because the monitor measures the weight, not the volume, of the grain hitting the flow sensor, test weight and different varieties do not cause calibration inaccuracies.

C Numbers

The 11 C Numbers, C1 through C11 determine the pounds that the monitor calculates from the data that it records into your loads as you harvest. You can display the C numbers under the GRAIN key. Changing the C numbers changes the pounds in every load set on that grain type for which the C numbers were changed. Anytime you calibrate the monitor it adjusts the C numbers automatically.

The C numbers initially should be set to the same values that appear on your initial calibration sheet. (Refer to the Setup section). With the C numbers set at their initial value, your accuracy of grain weight measurement may be only in the +/- 20 percent range.

Note: After the monitor adjusts the C numbers when calibration is complete, do not set them back to the initial values from the machine calibration sheet. If you do, you will change calibration accuracy.

June 1997

3-11

Calibrating Grain Weight

The C1 number is set to eliminate extra pounds that would be recorded from vibration when the separator is engaged and the combine is running empty. The C1 number is set by the operator manually and will not automatically change when the monitor is calibrated. Refer to the instructions on setting C1 in the Vibration calibration section.

Yield Monitor 2000

Ag Leader Technology

Calibration Loads

Grain Flow Rate

The Monitor calibrates itself on the basis of actual load weights you enter into the monitor. You obtain actual load weights by weighing the grain of a load in the monitor on accurate scales (elevator, calibrated weigh wagon). When you enter an actual weight for a load into the monitor, that load becomes a calibration load. Any load (that has pounds of grain in it) in any field in the monitor can be a calibration load at anytime.

The monitor’s calibration can be very accurate because the monitor calibrates a specific calibration value for virtually every level of grain flow rate or amount of grain that goes through your combine that the flow sensor is measuring. The grain flow rate that your flow sensor measures changes as the travel speed of the combine changes or the crop yield changes.

Note: The monitor, however, can calibrate only for the grain flow rates that were moving through your combine at the time the calibration loads were harvested. You must change your grain flow rates (by varying travel speed or swath width) from one calibration load to the next or grain weight will not be measured accurately.

Calibration Accuracy

3-12

For accurate calibration results, you must obtain at least six calibration loads (loads with actual weights). Each calibration load must be harvested under a different grain flow rate by varying either your travel speed or your swath width. You should achieve accurate calibration

results with no more than 10 to 15 calibration loads; if you do not, something is wrong and you need to troubleshoot grain weight calibration.

Calibrating Grain Weight

Harvesting Calibration Loads

Carefully follow these directions to calibrate your monitor for grain weight:

Step Action

1 With the combine stopped, the combine grain tank empty, and a

hauling vehicle empty, set the monitor on a data load (arrow to the right of the load number L1-> on the display) that has no data in it. If desired, name the load for future reference. Make sure the load is set on the correct grain type by pressing the GRAIN key.

Note: Follow these procedures to set the monitor on a data load:

Step Action

1 Either start a new load or display a load already created and: 2 Press the MEM key until “CHANGE TO THIS LOAD?” is

displayed.

3 Press the YES key.

2 Decide the speed at which you will drive or the swath width you will

use for this load to vary the grain flow rate going through your combine. Try to keep your speed or swath width as consistent as possible for the entire load.

Example Calibration loads (Ld) with varying speed (S) or swath width (SW):

Ld 1 Ld 2 Ld 3 Ld 4 Ld 5 Ld 6 S (mph) SW (rows)

3 Harvest grain into the calibration load in the monitor. The moisture

content of the grain does not matter.

Recommendation: Harvest 3,000 or more lbs for calibration loads.

Notes:

• If you are using a weigh wagon to weigh the grain, make sure the

wagon has been calibrated properly.

• Be absolutely sure that the measured and actual weights

correspond, which means that:

• The combine’s grain tank was completely empty when the

load was started

• The grain tank was completely empty when the load was

finished

• All the grain from that monitor load went into the same

vehicle

• No other grain, such as from another combine, was loaded

into the vehicle

Entering Actual Load Weights

3-14

As you obtain actual weights from the calibration loads, you can either enter the weights in the monitor one at a time and calibrate after entering each load or wait until you obtain them all, enter them all at once, and then calibrate. Both methods produce the same calibration accuracy. Enter the actual load weights as follows:

Step Action

1 Display a load for which you have an actual weight (lbs). 2 Press the WEIGHT key to display the measured lbs the monitor

calculated.

Note: You may repeat steps one through five and enter all your actual weights at once and then proceed with the next steps, or you can proceed with the next steps now and calibrate each time you enter an actual weight. Either method produces the same results.

Calibration Procedure

Follow these steps to calibrate the yield monitor:

Step Action

Set the monitor to any load that is of the grain type you want to calibrate. Press the GRAIN key to verify the correct grain type.

2 Press the GRAIN key until “CAL LBS NOW?” appears on the

top line of the monitor for a few seconds, then the message changes to “x.x% MAX, x.x% AVG ERR”, and finally, the monitor beeps and the message “PRESS ANY KEY TO CONTINUE” appears or “CONTINUE WITH LBS CAL?” appears (if you have entered four or more actual weights) on the bottom line of the display.

Note: The average and maximum errors tell you the accuracy of your grain weight calibration. It is extremely important to look for a high average and maximum error for every time you perform a calibration.

Press the NO key and then hit any key to advance through each calibration load and its calibration error. Write down the calibration loads and errors of loads with errors of +/- 15 percent or higher. Press any key to advance through each calibration load and its calibration error. Write down the calibration loads and errors of loads with errors of +/15 percent or higher. If you have 4 or more actual weights, CONTINUE WITH LBS CAL? will be displayed. Press the YES key to continue with the full calibration and go to step 8, otherwise PRESS ANY KEY TO CONTINUE will be displayed and the errors you have are your final errors until you can enter 4 or more actual weights and fully complete the calibration.

Example:

An example of a calibration load and its error is “F2/L1 +1.0% ERROR”. This means that the weight of the grain that the monitor measured in field 2 load 1 is +1.0% higher than the actual weight that was entered for that load.

5 If you find calibration loads with calibration errors of higher than +/-

15 percent, display those loads, one at a time, on the top line and check the following:

• Is the grain type correct for this load?

• Is the moisture reasonable for this grain type and field?

• Is the actual lbs value correct for this load?

4 Press the GRAIN key to display “CAL LBS NOW?” 5 Press the YES key to perform another calibration. 6 Verify that the maximum error is less than +/- 15 percent. If it

is not, zero out the actual weight in the calibration load with the next highest error.

Your goal after completing a full calibration should be to achieve an average error of 1 percent to 3 percent and a maximum error of 3 percent to 5 percent. Once the full

calibration is complete, the monitor displays the final average and maximum error.

Recalibrating the Monitor

Note: The monitor takes 1 to 2 minutes to complete a full

calibration.

9 If you have high final average and maximum errors, press any key to

scroll through each calibration load and its error. Write down each error and then zero out the actual weight in the load with the highest error as mentioned in the above steps. Perform another calibration and observe your new average and maximum errors.

You can add or delete a calibration load and recalibrate the monitor any time during the season to improve the monitor’s calibration accuracy. If you have not achieved satisfactory calibration results after entering 10 to 15 calibration loads (with varied flow rates) something is wrong. Refer to the Troubleshooting section instead of adding more actual weights.

Periodic Checks for Accuracy

Adjusting for Chain Slack

Check the monitor for calibration accuracy periodically throughout the season by weighing a monitor load of grain. If you find the monitor is not accurate, enter that actual weight into the monitor and calibrate the monitor again.

Note: If you do not vary your flow rates while harvesting your initial calibration loads, later in the season you may find the monitor is not accurate because you are harvesting at a different grain flow rate than for what you have calibrated. Entering one or two more calibration loads at that grain flow rate will improve your accuracy greatly.

If you adjust for slack in your clean grain elevator chain during the season, make sure that you use the lower adjuster. If you move the top shaft of the grain elevator, your calibration will be inaccurate and you will have to enter all new calibration loads.

Introduction

Monitor Organization

If you are using the monitor with a GPS receiver, you must use a memory card to save GPS information. If you do not have a GPS receiver, you do not need a memory card; the monitor has enough internal memory for 976 total loads and 255 total fields which should last the entire season.

Options: The monitor also can be connected to a sprayer controller or planting controller and record planting or sprayer data for mapping. Refer to the Options section.

Front Panel Description

Keypad

The memory card slot is built into the monitor. The monitor has an area count switch and an area count light on the front panel underneath the memory card slot. Refer to Figure 1.

The power switch is a white rocker switch on the bottom side of the monitor, below the left side of the front panel. A red reset button and the monitor fuse are to the right of the white power switch.

An alarm is on the bottom of the monitor, below the front panel. The shutter adjusts the alarm volume.

Starting, Changing, Naming

Fields/Loads

Recommendations

Data Load and Display Load

It is strongly recommended that you create and name your fields and loads before you begin harvesting. The best way to keep track of the fields year after year is to assign a name to a field and use that name every year in the monitor. It will not work to keep track of your fields year after year with the field number because of how the monitor creates the fields and because Precision Map 2000 and other mapping programs keep track of the fields based on field names. You can name your fields and loads on the monitor or connect your monitor to a computer and use the computer to name the fields and loads. Refer to the Setup section for directions for creating and naming fields and loads using a computer.

The monitor has two types of loads: display and data

The data load is the load into which information is recorded while you harvest. It is the load with an arrow to the right of the load number

(example: F1-> L1->). All other loads (display loads) have a colon to the right of the load number (example: F1-> L2:).

Note: You must know which load is the data load at all times or you might put yield information in the wrong field and load while harvesting. You can display a display load on the monitor while you harvest, but the monitor will not enter yield data in that load until you make it a data load.

Starting/Changing Fields and Loads

Follow these steps to start or change the field:

Step Action

1 Press the FIELD key to display the field alone on the top line of the

display.

2 Use the top UP or DOWN ARROW keys to change to another field.

Note: When you display the field on the top line by itself, the yield information on the bottom line is for field totals.

3. To start a new field, on the last field press the UP ARROW key to get:

3a. “START NEW FIELD?”. Press the YES key.

Introduction

Yield

This document provides instructions for monitor keys you can press to display useful information as you harvest.

• Press the INST YIELD key to display the instantaneous dry yield in

bu/ac while you are harvesting. The monitor displays a new instantaneous bu/ac yield reading every one second.

• Press the AVG YIELD key to display the average dry yield in bu/ac for

either the field or the load, depending on which is displayed on the monitor.

If you are not harvesting and you press the INST YIELD key, the average dry yield in bu/ac appears the same as pressing the AVG YIELD key. Thus, when you are displaying instantaneous yield and you arrive at the end of a row and turn around, the instantaneous yield switches to the average yield of the displayed load until you turn around to begin a new pass.

If you press the INST YIELD key twice you will display “xxx MAX BU/AC”. This is the maximum dry bu/ac yield reading that the monitor recorded for a 10-second period for either the field or the load, depending on which you have displayed.

Moisture

Press the MOIST key to display “xx.x%” while you harvest. The monitor displays a new instantaneous moisture reading every one second. If you are not harvesting and you press the MOIST key, the average moisture for the field or load appears on the display. Therefore, when you are displaying the instantaneous moisture and you arrive at the end of a row and turn around, the instantaneous moisture switches to the average moisture of the displayed load until you turn around to begin a new pass.

Refer to the Moisture document in this section for instructions about further settings related to moisture readings. Refer to the Calibration section for instructions about calibrating moisture.

Swath Setting

Introduction

Cutting Swath

Head Swath

The monitor’s swath setting can be different for each grain type. The monitor uses the number of rows and row space you set in the monitor to determine the total swath by which to calculate acres. The monitor has two swaths at all times for each grain type:

• Cutting swath

• Head swath

The cutting swath and the head swath in the monitor are set the same except when harvesting a partial swath; then the cutting swath is less than the head swath. Press the SWATH key to see both swaths.

The cutting swath is the swath the monitor uses to calculate acres. You can use the cutting swath to set the monitor on a temporary partial swath when you harvest point rows or finish a field.

The Head swath is the total swath of your combine head. It does not change unless you change the head on the combine.

Changing Number of Rows and Row Space

Follow these steps to view and change the number of rows:

Step Action

1. Display a load of the desired grain type.

2. Press the # ROWS key to display “x ROW CUT--x ROW HEAD”.

Note: The cursor must be under the x ROW CUT value if you want to change the cutting rows or under the x ROW HEAD value if you want to change the head rows.

Swath Setting

Yield Monitor 2000

Ag Leader Technology

Step Action

2 Use the RIGHT and LEFT ARROW keys to move the cursor under

the value you want to change.

Notes:

• The cursor initially will be under the x ROW CUT value when

the # ROWS key is pressed.

• When you change the number of head rows the cutting rows

value automatically jumps to the same number as the head rows. The number of cutting rows can never go above the number of head rows.

• After the number of head rows is set, you should never have to

change it unless you change heads.

3 Use the top UP or DOWN ARROW keys to change the numbers.

Recommendations for Row Crop Heads:

• For row crops, set your row space to the planted row spacing and your

number of rows to the number of total rows of your combine head.

Changing Row Space

Recommendations for Cutting Platform Heads:

• Set the swath in the monitor to one foot less than the actual swath width

of the head because you can rarely maintain a constant full swath while harvesting.

• Set the monitor on a row space of 12 inches and a number of rows that

adds up to the correct swath.

Example: If your cutting platform head is 20 actual feet, set the monitor’s swath to 19 feet by setting the row space to 12 inches and the number of rows to 19. Setting the row space to 12 inches for cutting platforms allows you to reduce the cutting swath by easier-to-see onefoot increments when you are harvesting a partial swath.

Follow these steps to view and change the row space:

Step Action

1 Press the ROW SPACE key. 2 Use the top UP or DOWN ARROW keys to change the row space.

4-20

June 1997

Yield Monitor 2000

Swath Setting

Partial Swath

You can change to a partial swath while you are harvesting. Adjust the cutting swath, not the head swath, to set a partial swath. To set the monitor on a partial swath, do either of the following:

• Reduce the number of cutting rows by pressing the # ROWS key

(reducing the cutting rows reduces the cutting swath)

• Reduce the cutting swath by pressing the SWATH key.

Use the top DOWN ARROW key to change either one.

Recommendations:

• For cutting platforms, set a partial swath by reducing the cutting swath.

Because the cutting swath reads in total feet, the swath is easier to visualize on a cutting platform head.

• For row crop heads, set a partial swath by reducing the cutting rows.

When the monitor is set to a partial swath (cutting swath is less than head swath), it chirps every four seconds and displays “LESS THAN FULL SWATH” to alert you that you are set on a partial swath. When you finish harvesting a partial swath, you must set the cutting rows or cutting swath back to the same value as the head rows or swath.

Setting Moisture

Yield Monitor 2000

Ag Leader Technology

Setting/Changing Moisture

The operator can set the monitor to take readings from the moisture sensor automatically or he/she can set an average moisture manually. The moisture is set to automatic or manual for each load. The monitor comes from the factory set on automatic moisture. You should use the automatic moisture setting unless you have a problem with the moisture sensor or you do not have a moisture sensor.

Follow these steps to change the moisture setting. Note: Any new loads you create will have the same moisture setting as that of the last load in the same field.

Step Action

1 Press the LOAD key to display a load on the top line of the display. 2 Press the MOIST key until “MOIST=AUTO or MAN” appears on

the display.

3 Use the bottom-left UP or DOWN ARROW key to select AUTO or

MAN.

4 If you set MOIST=MAN, you must enter an average moisture value

for that load. Press the MOIST key until “xx.x AVG %” appears on the display.

5 Use the bottom-left UP or DOWN ARROW keys to set an average

moisture value for that load.

Buildup on the Sensor

4-22

The moisture sensor can give readings that are too high if sticky material from weeds or green stems buildup on the moisture sensor. This is normally only a problem in soybeans with a lot of weeds or green stems. If you have high moisture readings, remove the moisture sensor from the combine tank fill auger, check it for buildup, and clean it. After cleaning, continue harvesting. If the buildup condition is severe, you may not be able to keep the moisture sensor clean. In such conditions, set the moisture for the load on manual and enter the average moisture for that load as instructed above. After buildup conditions cease, set the moisture back to automatic.

Notes: If buildup is severe, check your flow sensor for buildup on the impact plate attached to the black load cell. The monitor either uses all the automatic readings or only the manual moisture value (depending on whether MOIST=AUTO or MOIST=MAN) for the entire load.

Acre Counting

Area Count Light and Switch

Stop Height

The area count light indicates when acres are being counted.

• Off - Counting acres

• On - Not counting acres (red)

The area count switch (underneath the memory card slot) manually or automatically stops and starts counting acres on the ends when you turn around.

When the area count switch is in the up position, the monitor refers to the position of the head to start and stop counting acres. When the head is raised above a set height (stop height) on the row ends, the monitor stops counting acres and the area count light is on. After you turn around and the head is lowered below a certain height, the monitor starts counting acres and the area count light is off.

Note: When the area count switch is in the down position, the red light is on and you will not count acres regardless of the head position.

The stop height number in the monitor determines at what head position the monitor will start and stop counting acres. Press the STOP HEIGHT key and use the top UP or DOWN ARROW keys to change the stop height number. The higher the stop height number, the higher the head must be raised to stop counting acres. The lower the stop height number, the lower the head needs to be raised to stop counting acres. The stop height number can be set differently for each grain type. The stop height setting normally will be between 55 and 80.

MAX AC Stop Beeps

When you have engaged the separator and you raise the head on the row ends, the monitor beeps to alert you that you have raised the head high enough to stop counting acres. If lowering the head stops the beeping, you will have an audible signal that you have lowered the head enough to start counting acres again. Press the SETUP key to display “MAX AC STOP BEEPS”. Use the top UP or DOWN ARROW keys to change the number.

Recommendations:

• Set the MAX AC STOP BEEPS number high enough that the beeps do

not end before you lower the head after turning around.

• Usually a MAX AC STOP BEEPS value of 20 to 30 is high enough.

Speed Setting and Distance Calibration

The monitor can record its ground speed from three different sources:

• Ground speed sensor on combine

• Radar gun

• GPS (GPS 2000, Trimble AgGPS 120, 122, must have VTG data string)

The monitor has six different speed setting. The speed settings are set for each load. With a load displayed press the DIST key until “SPD=” is displayed. Use the bottom right UP or DOWN ARROW keys to select:

• WHL (wheels)

• TRK (tracks)

• RAD (radar)

• GPS/WHL

• GPS/TRK

• GPS/RAD

You have to calibrate distance for wheels, tracks, or radar speed settings, depending on which ones you use for your distance and acre counting to be correct. Refer to the Calibration section for instructions.

If you are getting your ground speed from a GPS receiver, you still must select either wheels, tracks, or radar as a backup speed sensor. If the GPS signal is lost, the monitor will take readings from the backup speed sensor.

Adjusting Load Acres

4-24

You can correct the acres for an entire field or load after you have finished harvesting by two methods, but you must have the field and load displayed. Follow these steps to correct the acre calibration:

Step Action

1 With a load displayed, press the AREA key until “AC

CAL=xxx.x%” appears on the display.

2 Use the bottom-right UP or DOWN ARROW keys to change the

value.

Follow these steps to change the displayed acres:

Step Action

1 Press the AREA key. 2 Use the bottom-right UP or DOWN ARROW key to change the

June 1997

Yield Monitor 2000

Ag Leader Technology

If you incorrectly set the swath for a load, it is easier to adjust the acre calibration number by a percentage than to adjust actual acres.

Use the following equation to calculate the acre calibration number when the incorrect number of rows has been set.

Correct #Rows / Incorrect #Rows x 100 = Acre Calibration

Example: If # rows were set on six instead of eight rows, you would set the acre calibration number to 133 percent because 8/6 x 100 is 133.

Acre Counting

Adjusting Field Acres

If you know the exact field acres, adjust the monitor field acres to the correct value after you finish harvesting the field. Follow these steps to adjust the field acres:

Step Action

1 Display the field on the top line by itself. 2 Press the AREA key to display acres. 3 Use the bottom right UP or DOWN ARROW keys to set the field

acres to the correct value.

Notes:

• The monitor proportionally adjusts all the load acres.

• Usually, the monitor slightly over counts acres because the

combine head is not raised and lowered fast enough on the ends.

You can have only one grain type per field. If you have one field with two different crops in it (example: 80 acre field with 40 acres of soybeans and 40 acres of corn), you must use two fieldsone for each grain typein the monitor.

Each grain type has the following settings.

• Grain calibration numbers (C2-C11, monitor sets these when calibrated)

• Moisture calibration number

• Dry % value (for example, 13% for soybeans)

• Dry lbs/bu

• Vibration calibration number (C1)

• Swath setting

• Stop height number

You can set the dry lbs/bu of the grain for each grain type except corn (56 lbs/bu), soybeans (60 lbs/bu), and wheat (60 lbs/bu). Follow these steps to set the dry lbs/bu:

Step Action

1 Press the GRAIN key until “xx DRY LB/B” appears on the display. 2 Use the bottom-left UP or DOWN ARROW keys to change the

value.

Note: This will change the bushels for all loads set on that grain type.

Follow these steps to set the dry % value:

Step Action

1 Press the GRAIN key until “xx.x DRY %” appears on the display. 2 Use the bottom-left UP or DOWN ARROW keys to change the

value.

Note: This will change the bushels for all loads set on that grain type.

Changing Grain Type Name

You can change any of the existing grain type names (except the four corn types) to any name (up to 11 characters long) of your choice. Follow these steps to change the grain name:

Step Action

1 Press the LOAD key to display a load and then press the GRAIN key

to display the grain type.

2 Use the bottom-left UP or DOWN ARROW keys to change the grain

type to the one that you want to change the name.

3 To get a cursor (underline character) to appear to the left of the

grain type name, press the WEIGHT key once and then press the GRAIN key again to display the grain type again on the bottom-left of the display. You should now see a cursor to the left of the grain type name.

4 Use the RIGHT ARROW key to move the cursor over to the first

character that you want to change. Use the bottom-left UP or DOWN ARROW keys to scroll through the characters that can use for the new name.

5 Repeat step 4 and change the characters necessary for the new name.

Note: Changing the name of the grain type does not affect any of the other settings or calibration numbers that are associated with that grain type.

Copying Calibration Numbers to another Grain Type

Note: To change all the grain type names back to their original names shut

the monitor off, hold down the GRAIN key and turn on the monitor.

You can copy the grain calibration numbers (C1-C11 numbers) from one grain type to another (exception: can not copy to or from a non-corn type to a any of the four corn types). This feature is useful if you change to a grain type that has the same calibration as another grain type. Follow these steps to copy the calibration numbers:

Step Action

1 Press the MEM key until “PRESS YES TO COPY CAL” is

displayed.

2 Use the bottom-left UP or DOWN ARROW keys to change to the

grain type for which you want the calibration numbers copied from.

3 Use the bottom-right UP or DOWN ARROW keys to change to the

grain type for which you want the calibration numbers copied to.

4 Press the YES key.

Setting/ Changing Grain Type

When you create a field, “SET GRAIN/PRESS YES” appears on the display, and a grain type appears in the bottom-left corner of the display. Follow these steps to set the grain type:

Step Action

1 Use the bottom-left UP and DOWN ARROW keys to scroll through

the grain types to highlight the type you want.

2 Press the YES key to set the new field to that grain type.

Although you can use only one grain type in a field, grain type is set load-byload. When you create new loads in a field, the monitor sets the grain type of the created load to the grain type of the last load in that field. When you press the YES key to set the grain type when a field is created, the monitor actually is setting the grain type for load one in that field.

To change the grain type of an existing field, you must display every load in that field, one at a time, then change the grain type of each load. Follow these steps to change a grain type:

Step Action

1 Display a load, then press the GRAIN key until the grain type

appears on the display.

2 Use the bottom-left UP or DOWN ARROW keys to change the grain

type.

Note: If you display the field alone on the top line and press the GRAIN key to display the grain type, you will not be able to change the grain type because you must change it for each load in that field.

If you harvest loads set on the wrong grain type, you can change those loads back to the correct grain type on the monitor, except when you are changing either to or from CORN or SPECIAL CORN (all other grain type combinations can be changed from one to another to provide correct weight calculation).

Memory

Yield Monitor 2000

Ag Leader Technology

Introduction

Main Memory

Backup Memory

The monitor has its own memory, apart from a memory card, for which it stores all data (except global positioning system {GPS} data) for all the fields and loads for an entire year. The memory card is used to save the logged GPS and yield data for yield mapping. The monitor’s own memory can hold up to 976 total loads and 255 total fields. The monitor has two types of internal memory:

• Main memory

• Backup memory

Note: If you have a computer with Windows 3.1™ or Windows 95™ or you are logging data to a memory card, you can print a summary of all the yield data for the entire season (usually at the end of the year).

The main memory is the primary memory that contains all yield data for all fields and loads. The monitor automatically adds yield data to the main memory as you harvest. The fields and loads you see on the monitor’s display are all in the main memory.

The backup memory is secondary memory that is provided to back up yield data in case the yield data in the main memory is erased or becomes corrupt. Yield data, as you create new loads and add new data, does not save to the backup memory automatically; it is saved only to the main memory. You must manually copy the main memory to the backup memory, otherwise you will not have a backup copy of your data if you have a system failure.

Copying Main Memory to Backup Memory

4-28

It is extremely important to copy your main memory to the backup memory at least once a day. Follow these steps to copy the main memory

to the backup memory:

Step Action

1 Press the MEM key until “COPY MEMORY TO BACKUP?”

appears on the display.

2 Press the YES key.

June 1997

Yield Monitor 2000

Follow these steps to copy the main memory to the backup memory as you shut off the monitor:

Step Action

1 Shut off the monitor. The message “COPY MEMORY TO

2 Press the YES key. When the monitor is finished, press any key to

Memory

BACKUP BEFORE POWER OFF?” appears on the display.

return to the normal display. The monitor automatically shuts off after it copies memory to backup.

Note: The message “COPYING TO BACKUP” appears on the bottom line of the display. If you have a memory card installed in the monitor and the monitor is set to log to a card, the monitor also copies memory to the card. The monitor requires two to three minutes to finish copying to the backup memory. If you press the NO key to bypass copying memory to backup, the monitor shuts off.

Restoring Memory From Backup

When you copy memory to the backup, the monitor erases everything in the backup memory and replaces it with the data in the main memory. When you copy memory to backup, these three messages appear, one after the other, on the top line of the display:

• “X % BACKUP PREPARED”

• “PLEASE WAIT X”

• “X% COPIED”

It is very dangerous to restore memory from backup because everything in the main memory is erased and replaced with backup memory data. Make sure the data in the main memory is really corrupt before you proceed. If you erase the main memory or it is corrupt, you can

retrieve the yield data from the backup memory by following these steps.

Step Action

1 Press the MEM key until “RESTORE MEM FROM BACKUP?”

appears on the display.

2 Press the YES key.

Note: Because restoring memory from backup erases the main memory data and replaces it with backup memory data, the monitor asks you twice whether you want to erase the main memory data.

3 Press the YES key for both questions if you want to replace the

main memory data with the backup memory data.

Memory

Yield Monitor 2000

Ag Leader Technology

Retrieving data from the backup memory is something you should have to do only when there is a problem. The yield data in the main memory rarely becomes corrupt. Corruption usually occurs while operating a high-power electrical device on the combine, such as an engine starter or an electric feeder reverser.

Important: You will know the data is corrupt when you see strange characters or strange field and load numbers and names on the monitor.

Refer to the Memory Card document in this section for information on copying data to and restoring data from memory cards.

Clearing Fields/Loads From

Memory

Introduction

Clearing Individual Loads

The Yield Monitor allows you to clear fields and loads from the memory on two levels:

• You can clear data that is collected into loads by clearing them

individually.

• You can clear all fields and loads in the monitor, leaving only Field

1/Load 1.

Recommendation: Clear all fields in the monitor before beginning a new harvest season. When you clear all fields, the monitor allows you to save all the calibration loads and/or keep the field names, but erase all other loads.

You can store up to 976 loads and 255 fields in the monitor, which is normally more than enough for one year. Press the MEM key until “xxx LOADS REMAINING” appears on the display to see how many new loads the monitor has available.

Follow these steps to clear data that has been accumulated in a load:

Step Action

1 Press the FIELD and LOAD keys and then use the top UP and

DOWN ARROW keys to display the load you want to clear.

2 Press the MEM key until “CLEAR DATA IN THIS LOAD?”

appears on the display.

3 Press the YES Key. The monitor will beep four times quickly and

“ARE YOU REALLY SURE?, YOU WILL LOSE DATA!” will appear on the display.

If you . . . Then . . .

Want to continue to clear the data from this Load, If you have changed your mind about clearing the load,

Press the YES key again.

Press any other key.

Clearing Field/Loads From Memory

Notes:

• Even though you may have collected some data with incorrect monitor

settings, do not clear out actual harvest data. Many times, it is possible to correct bad data by correcting settings or calibrations later.

• Clearing a load does not eliminate it. It only zeros the load’s data.

Yield Monitor 2000

Ag Leader Technology

Clearing All Fields in the Monitor

Follow these procedures to eliminate all the fields and loads in the monitor.

Note: Normally, you will clear the monitor only when you are preparing to begin a new harvest season.

Step Action

1 Press the MEM key until “CLEAR ALL FIELDS?” appears on the

display.

2 Press the YES key. The monitor beeps four times quickly and “ARE

YOU REALLY SURE?, YOU WILL LOSE DATA!” appears on the display. Press the YES key.

Note: If you have changed your mind about clearing the monitor, press any key other than the YES key.

3 “KEEP CAL LOADS?” appears on the display.

• Press the YES key if you want to keep all the calibration loads so

you can use the current calibration for the next harvest season.

• Press the NO key to also delete the calibration loads.

Note: If you are satisfied with the current grain weight calibration, keep the calibration loads. If you keep the calibration loads, you can use your old calibration loads next year’s calibration. You still may have to enter a few new calibration loads depending on if your old calibration was done over a wide range of grain flow rates.

4-32

If you plan to replace the clean grain elevator chain before the next harvest season or you are going to adjust the top shaft, you should not keep the old calibration loads.

Your old calibration loads will be in Field 0. The name of the field will be CAL LOAD, and each load will be named with the original field and load numbers.

Step Action

4 “KEEP FIELD NAMES?” appears on the monitor display.

Clearing Fields/Loads From

Memory

• Press the YES key to keep all the existing fields and field names.

• Press the NO key to delete all the existing fields and field names.

Recommendation: If you want to delete the names of only some of the existing fields, it will still save you time to keep all the field names and use a computer or the monitor to delete the field names you do not want to keep. To delete the field names on the monitor, set each character of the field name to a space. The space character is between the 9 and the A as you press the ARROW keys to scroll through the list.

If you keep the field names, the monitor leaves one load in each field, but erases the yield data for the field and all the loads in the field. The monitor selects the following settings for every Load 1 in every field:

• Grain type remains the same

• Moisture is set to AUTO

• Speed remains the same

Go through each Load 1 in each field and set the grain type to the crop you will harvest in that field next season after you have

erased all the loads but kept the field names. Also, make sure the moisture and speed settings are correct for every Load 1.

5 The monitor beeps four times again and “REALLY WANT TO

ERASE FIELD DATA?” appears on the display. Press the YES key to erase, otherwise press any key other than the YES key to bypass erasing.

Notes:

• If you decide that you should not have cleared the monitor, you can

restore main memory from backup if you copied the main memory to the backup memory before you cleared the monitor.

• Clearing the monitor does not change the distance, moisture,

temperature, or C1 calibration numbers.

Logging Map Data to a Card

Yield Monitor 2000

Ag Leader Technology

Important

Introduction

Never leave a memory card in the monitor when the monitor is shut off. If you do so, it will drain the batteries of the monitor and your data will become corrupt.

The yield monitor can read position information from a GPS receiver and record data for yield mapping. To save GPS data, you must use a memory card or datalogger. Refer to Important Notes below for more information on Memory Cards.

Using a memory card to log yield map data has the advantage that all the field, load, and calibration information from the monitor's memory is copied to the card, which allows for later recalibration of the yield map data.

Example: If you wait until the third field you harvest before calibrating the monitor, your GPS yield data for the first two fields will automatically be recalibrated when you calibrate in the third field.

Note: This capability is only available when you log data to a memory card. It is not available if you use a datalogger.

Important Notes

• You must copy memory data to a card before you read the memory

card into your computer. You must use Precision Map 2000 software

or other mapping software to download and archive data on a memory card. When you copy data to the backup memory, the monitor automatically copies the data to a card if the logging device (accessed by pressing the SETUP key) is set to a card and the memory card is installed in the monitor.

• If the message “COPY FAILED - TRY AGAIN” appears on the monitor

display when you are copying data to or restoring data from a card, you probably have a bad card.

• If you install a card that has the write-protect switch on, the monitor

displays “MOVE SWITCH ON CARD”. Use the tip of a pen or pencil to move the small switch on the outer end of the card.
