1-1

Pub. #OM17-MSP3

Important! Read the following SAFETY PROCEDURES before operating the Veris system:

• Read and understand all instructions on safety decals

• Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard
by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card-board,
NOT BODY PARTS, to check for suspected leaks.

• Wear protective gloves and safety glasses or goggles when working with hydraulic and high­pressure wash systems.

• If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically

removed within a few hours or gangrene may result.

• Pinch point hazard: to prevent injury, stand clear when raising or lowering any part of the Veris
implement.

• Install all transport locks before transporting or working underneath.

• Detach and store implements in an area where children normally do not play. Secure implement

by using blocks and supports.

• Read Operations Manual before operating machine

• Review safety instructions with operators before operating machine and at least annually

• Never stand on or use tire as a step

• Do not tow the implement on public roads without the road-kit light package, or without the proper

safety equipment and licensing as required by your State Department of Transportation. Always
use safety chain.

• Riders obstruct the operator’s view. They could be struck by foreign objects or thrown from the

machine.

• Never allow children to operate equipment.

• To prevent possible electrical shock, or damage to the instrument, do not connect to any power

source greater than twelve (12) volts DC.

• Do not grease or oil implement while it is in operation.

• Disk edges are sharp. Be careful when working in this area.

• Disconnect battery ground cable (-) before servicing or adjusting electrical systems or before

welding on implement.

Statement of Use

Intended use of the Veris MSP3 model

The Veris MSP3 Soil EC, Organic Matter, and pH Mapping System collects geo-referenced soil
electrical conductivity (EC), soil reflectance, and soil pH measurements as it is pulled across a field

by a tractor. An electronic device called the Soil EC Surveyor, powered by vehicle’s 12V DC

electrical system, generates a small electrical current, which is transferred into the soil through a
pair of rolling electrode coulter disks. A second pair of disks measures the drop in voltage which is
proportional to the electrical conductivity of soil medium at a given location. Signal response is due
primarily to soil texture/grain size and soil salinity. Clay soils and soils with high salinity levels are
highly conductive, while coarser soils such as sand do not conduct well. Another electronic device
called the OpticMapper controller, powered by vehicle’s 12V DC electrical system, sends power to
an optical sensor which has two wavelengths of LEDs and measures the amount of light reflected
off the soil surface with a photodiode. The optical sensor is mounted inside a standard row planter,
with two discs to cut a furrow in the soil and two depth gauge wheels to keep the sensor at
constant depth. Signal response is due to soil color, darker soils are generally higher in Organic
Matter; while lighter soils are lower in Organic Matter. A final electronic device called the pH

controller, powered by vehicle’s 12V DC electrical and hydraulic system, measures soil pH using

two electrodes. The pH controller cycles the pH sampling shoe into the soil, where a soil core is
collected and brought up and pressed against the electrodes for a measurement. Once a stable
reading is measured, the sampling shoe moves down to collect another soil segment, and the
electrodes are washed off. This process is repeated every 20-30 seconds, as long as the operator
keeps the system engaged, and ground speed is received. The sampling shoe is controlled by
hydraulic solenoids, while the wash jets are powered by two 150 psi pumps. The system records
the data either on its own datalogger, or on a data recording device such as a laptop computer.
Ultimately, the data are displayed in a map format, and variable applications of crop production
materials, such as seed, fertilizer and other inputs are variably applied to the zones delineated on
the maps. The MSP3 system is designed for use in a farm field, and has no dynamic movement
unless vehicle is pulling it, or operator is manually activating switches, so guarding around soil
engaging components is not needed and would interfere with field operations. Unit should not be
operated when people are present in the field, as coulter disks are sharp and automated
movement could cause injury if contact occurs.

Misuse of the Veris MSP3 model

Misuses of the MSP3 model include operation with people in area, and pulling the system at an
excessive speed. In field position, this could result in poor data collection and possible tractor
overturning at extremely high speeds and sharp turns. In raised position, the chance of
overturning is increased, as the center of gravity is higher, so care must be taken to keep speeds
under 15 km/hr, and less when turning.

Abnormal use of the Veris MSP3 model

Abnormal use of the MSP3 model includes using it as a cart for carrying equipment, tools, or
people. Under no circumstances should anyone ride on the implement. Even though the
implement is similar in appearance to a tillage tool, such as a disk harrow, it was not designed for
that usage and should never be used for any purpose other than soil data collection.

If the unit has been crated and delivered via closed-van commercial freight, the tongue (if
equipped) may need to be installed prior to use. Prior to operating the implement for the first time,
it is important to check all fasteners – some may have loosened during shipment. Route cables
and hydraulic hoses along tongue and through hose guide. Tie-strap securely. Connect electrical
cables to battery. Be careful to attach black cable to negative/ground terminal. DO NOT
REVERSE POLARITY.

Figure 2
Insert hydraulic ends into quick-couplers, being careful to insert the end marked “P” into the tractor

extension coupler, and the end marked “T” into the tank or return line coupler; in this configuration,

tractor’s hydraulic lever will be secured in raised position. If sampler shoe operates in reverse,

simply reverse hydraulic hoses, or secure lever in lowered position. Note: Be certain whether
tractor or hydraulic power source utilizes open or closed-center hydraulics. Damage to
tractor could occur if not set properly. The poppet knob is set ‘up’ for open systems, and

‘down’ for closed-center systems – (see settings below.) Press down and turn knob to lock down—
press down, turn and release to allow it to move up to open position.

Flow control settings:

Open center hydraulic systems

1) Set poppet valve in “up” raised position, this allows flow back to tank

2) Set engine at field rpm

3) Set pH controller to “Manual” and run sampling shoe up and down, timing the cycle time.

4) If sampler raises in approximately 1.5 -2 seconds, leave flow control as is, if not, adjust control
arm upward or downward to achieve desired speed.

Closed center hydraulic systems

1) Set poppet valve in down position. Push down and rotate so that rolled pin locks into closed
position. This blocks flow and allows the pump to de-stroke when the directional valve is in
the neutral position.

2) Adjust flow control valve to full open position.

3) Set engine at field rpm.

4) Run sampling shoe upward and adjust raise time to approximately 1.5-2 seconds using
throttling valve on tractor’s remote coupler

Note: Excessive sampling shoe speed can
damage electrodes.

There are warning signals programmed into the Veris DataLogger to warn the operator that data is
not being recorded, so that corrective action can be taken. If data is not being recorded, a warning
alarm will sound, and the portion of the screen text that is missing information will blink. For

example, if the DGPS isn’t being received (or the NMEA string containing speed) the Lat/Long text

will blink. If EC values are negative, they will blink. Also, the Data Status LED light on the front of
the DataLogger indicates whether data is being recorded. If this light is not lit, data is not being
recorded. (note: no data is recorded unless unit is moving—receiving speed signal from GPS)

At any time during the mapping process, you can press any key to stop the file. If you create more
than one file from the same field, you can bring the files into a spreadsheet program or GIS and
combine for whole field map display.

On the DataLogger, press 1 to continue with calibration. The DataLogger will read the electrodes
for 10 seconds, displaying the output. After 10 seconds, the instrument will display the final pH
reading and offer the options to 1) Accept pH 7 buffer readings; 2) Redo pH buffer 7 readings; or 3)
Exit pH electrode calibration. If the readings are satisfactory, log pH 7 reading and press 1; if the
readings are suspect, press 2 to return to pH 7 calibration step.

After accepting the pH 7 buffer readings, the electronics firmware will determine if each electrode’s
response is sufficient to provide suitable readings. A score is displayed for each electrode; the
acceptable score range is between 75 and 102. If both electrodes are within this range, the
instrument will display the following screen:

Figure 24

If an ‘X’ is displayed beside one or both electrodes’ scores, this indicates that one or both of the

electrodes did not perform well enough for continued reliable use. No calibration settings are
changed if calibration is unsuccessful. The electrode(s) responsible for failed calibration should be
removed and either cleaned or replaced and the calibration procedure repeated.

Figure 25
After calibration is complete, you will have the option to use the calibrated readings or reset to the

ideal settings. Tip: many operators use the ideal settings rather than calibration settings. One

reason is this enables readings from one day to be compared to another. It is still important to
perform the calibration step at least daily, even if ideal settings are used. The calibration process
is important to test electrode quality.

Sampling time is the duration that the sampler assembly is in the soil. Typically 2 seconds is

adequate. In soil conditions that do not produce a firm core, this time may need to be set at 3
seconds in order to allow soil to begin flowing through cutting shoe. If soil conditions result in a
very firm core, the sampling time may be reduced to 1 second. In rocky conditions, use 1 second
sample time to reduce likelihood of sampler shoe damage. Press 1 or 2 to adjust the sample time,
press 3 to continue to the next screen.

Figure 29
Maximum log time is the longest time in seconds the pH controller will wait for the pH readings to

settle. The controller usually cycles before this maximum time is reached. The minimum setting
for the maximum log time is 20 seconds. (Tip: use 20 seconds unless there is a special reason to
allow a longer wait time) Press 1 or 2 to adjust the sample time, press 3 to continue to the next

The EC OM pH-MSP3 Mapping software will automatically detect which ports the Veris
OpticMapper /EC Controller and pH Controller are connected to, and begin communicating. If
either is not detected, the software will wait 45 seconds for the connection of the electronics and
search again; this will repeat until both instruments are connected. If the electronics are not found,
unplug the serial or USB cables and reconnect them to the PC. If the connections are still not
made, refer to SoilViewer troubleshooting. The conditions for mapping and storing the data are as
follows. The user must be going a speed greater than 1 mph, there must be a GPS signal
received that includes position and speed (GGA and either VTG or RMC), the OM/EC Comm Light
must be green, indicating the PC and OpticMapper with EC Surveyor are communicating properly,
and either of the EC values has to be greater than -1.

Before mapping, run the OM system check and pH calibration to ensure everything is

SoilViewer OM System Check

The OM System check ensures the optical sensor and controller are functioning properly. By using
the light and dark reference block the range of the sensor can be determined. For proper
operation the range from the dark to light side for the red and IR readings must be at least 100. If
it is not that may indicate a broken wearplate, inadequte power, or damaged sensor. Run the
system check before mapping each field to ensure proper operation. The results of the system
check are stored in a .inf file specific for each field.

Click the OM System Check button to start system check.

After accepting the pH 4 buffer readings, the software will prompt for the electrodes to be inserted
into pH 7 buffer solution. Remove the pH 4 buffer solution cup from the electrode holder. Rinse
the electrodes, electrode holder, and solution cup using the manual wash for at least 10 seconds.
Slide the pH buffer 7 solution cup onto the electrode holder.

offer the options to Accept pH 7 buffer readings; Redo pH buffer 7 readings; or Cancel pH
electrode calibration. If the readings are satisfactory, log pH 7 reading and press continue; if the
readings are suspect, press redo to return to pH 7 calibration step.

After accepting the pH 7 buffer readings, the software will determine if each electrode’s response

is sufficient to provide suitable readings. A score is displayed for each electrode; the acceptable
score range is between 75 and 102. If both electrodes are within this range, the software will
display the following screen:

Figure 47

If an ‘X’ is displayed beside one or both electrodes’ scores, this indicates that one or both of the

electrodes did not perform well enough for continued reliable use. No calibration settings are
changed if calibration is unsuccessful. The electrode(s) responsible for failed calibration should be
removed and either cleaned (See section 5-7) or replaced and the calibration procedure repeated.

Figure 48
After calibration is complete, you will have the option to use the calibrated readings or reset to the

default parameters. Tip: many operators use the default parameters rather than calibration

settings. One reason is this enables readings from one day to be compared to another. It is still
important to perform the calibration step at least daily, even if ideal settings are used. The
calibration process is important to test electrode quality.

Figure 50
The pH sampler settings can be adjusted without exiting the current file. Additionally, a correction

can be applied to each electrode’s pH shown on the screen. Occasionally, the pH readings shown

on the screen may differ from those expected in the field. If this is the case, the pH shown on the
screen can be adjusted up or down with the pH offset 1 and pH offset 2.

The offset is adjustable in 0.5 pH increments up to +/- 2.00 pH. NOTE: The instrument DOES
NOT apply this offset to the extracted file. Only the readings seen on the screen will be affected.

Sampling time is the duration that the sampler assembly is in the soil. Typically 2 seconds is
adequate. In soil conditions that do not produce a firm core, this time may need to be set at 3
seconds in order to allow soil to begin flowing through cutting shoe. If soil conditions result in a
very firm core, the sampling time may be reduced to 1 second. Press the up and down arrows to
adjust the sample time.

4-16

Pub. #OM17-MSP3

Log time is the longest time in seconds the pH controller will wait for the pH readings to settle. The
controller usually cycles before this maximum time is reached. The minimum setting for the log
time is 20 seconds. Press the up or down arrows adjust the sample time. (Tip: use 20 seconds
unless there is a special reason to allow a longer wait time)

Select the type of water you are using to clean the electrodes between samples. The available
types are TAP, RO (reverse osmosis), or DI (de-ionized). Tip: If you don’t want a baseline wash

performed every 40 cycles, use RO setting rather than Tap or DI (regardless of actual water being
used).

Turning on the extra wash option will add 1.5 seconds of cleaning per cycle. The extra wash is
performed by automatically stopping the shoe briefly during the cycle. Use this feature if you have
noticed the electrodes are not cleaning during the cycle. Put a checkmark in the box to turn the
extra wash on and uncheck to turn off the extra wash. Tip: water usage will double if extra wash is
used.

Checking Electrical Signal Continuity and Electrode Isolation

It is recommended that you perform the Electrical Signal Continuity and Electrode Isolation test
procedure before first field use (see Maintenance and Service Procedures 1 and 2). While these
tests were made at the factory, there is the possibility a problem developed during shipping.
Performing these tests on the new implement before it becomes dirty, allows you to get familiar
with the process under ideal conditions. It is strongly advised that you perform this test on a routine
basis (every 10 hours of data collection) to ensure you are obtaining reliable data. KEEP

OHMMETER, TEST LOAD AND TEST BOX WITH THE MACHINE AT ALL TIMES.
Setting Operating Depth

Begin field operation by lowering unit into soil. For good electrical conductivity, all coulter
electrodes must be in direct contact with moist soil, at all times and in every region of the field. A
depth of 1-2” (2.5-5 cm) is recommended. To insure this depth is consistently achieved, 400-600
lbs. (180-275 kg) of additional weight are normally required. Carrying water in the pH wash tank
can aid penetration. Also, Veris offers optional weights, or they can be supplied by the customer.
Do not adjust the tension on the coulter electrode springs to increase soil contact or penetration.
They are pre-set at the factory with the proper tension.

Adjustable Wing Extensions

This feature allows the re-positioning of the electrodes to fit various bed and crop configurations.
Adjustment is made by loosening the jam nuts and set screws located on the lower front of each
side of the toolbar, adjusting the toolbar wing extensions, and re-tightening the set screws. Veris
suggests setting the toolbars at either the maximum or minimum setting, not at a point in between.
A limiter bolt determines full extension, so they cannot extend to the point at which the outside
coulters disconnect from the main frame. Important – do not attempt to combine maps in which two
different investigative depths are used.

Top Link

3-point Adjustment

Turn the top link (Figure 60) to adjust the tilt and level the unit.
This is the optimal setting for all fields types. Extending the top
link will cause the rear of the unit to move down. Shortening the
top link will cause the inverse.

Row Unit Adjustment

Adjust side depth wheels on optical row unit to allow deeper or
shallower mapping. Move T-handle (Figure 61) backward for
deeper depth. Depth wheels should be snug, but freely moving,
against the disks. See Section 5-3 for more information.

Pub. #OM17-MSP3

Adjust spring pressure on row unit as needed. With implement
lifted to reduce pressure on springs, move handle forward to
reduce spring pressure and back to increase. Additional weight
may be required in hard soils. Reduce pressure in rocky
conditions to prevent damage to window. (Figure 62)

Row Cleaner Adjustment

The row cleaner needs to be adjusted for your
conditions, crop changes, and as coulters and
openers wear. Ideally, cleaners contact only the
trash, and do not disturb the soil.

To adjust row cleaner loosen bolts, 1, and slide
the down stop, 2, to the desired cleaning depth.
Forward for deeper cleaning and backward for
shallower cleaning.

Figure 63

Pub. #OM17-MSP3

Coulter Adjustment
Adjusting the coulter depth is accomplished by re-mounting the coulter blade in one of the six
mounting holes arranged in a staggered pattern in the coulter bracket.

Figure 64
Raise unit and lower service stands before
working on coulters. Do not attempt to move
blade when the current or new position causes
it to contact the ground during the adjustment.
Be careful around the front end of row units.
Row cleaner tines and coulter blades may be
sharp.

To adjust coulter depth:

1. Determine the present opener and coulter
depths.

2. Note which bracket hole the coulter is
presently using.

3. Determine which new hole will position the
coulter closer to the 1/4in-above depth. See

the table below.

4. Remove the 5/8-11 x 4in bolt, lock washer
and nut ( A in Figure 64).

5. Move the blade to the new position. Insert
the bolt, and tighten on the lock washer and
nut.

6. Re-adjust row cleaners, if installed. If a
worn coulter cannot be adjusted to
satisfactory operating depth, replace coulter.

Speed

Proper field operating speed depends on field condition. Because of the importance of consistent
contact, the unit must not be allowed to bounce over rough fields at high speeds.

Field Condition

Field should be in a uniform state. Mapping after intensive primary tillage is not recommended. The
soil must have a minimum of 20% available water, and cannot be frozen. If rocky conditions exist,
slow down and make sure rock guards are in place. Also if the field is rocky and/or muddy the
optical module will needs to be adjusted to make optimum contact with the soil, as well as
decreasing the chance for window breakage.

Swath width and Navigation

Setting the swath width and navigation system is at the discretion of the customer. A 50’-75’ (15­23 m) swath works well in most areas. Several methods of navigation are possible: following
previous crop rows, swath guidance, or using a field navigation computer. While it is important to

map in a consistent pattern, it isn’t absolutely critical that each pass be exactly the same distance

from the previous pass.

Pub. #OM17-MSP3

To help insure the quality of your data, please follow these guidelines:

1. Generate and view maps frequently, especially prior to deleting data from Instrument.

2. Listen for auditory alarm from DataLogger, indicating data collection has been interrupted.

3. View DataLogger screen or SoilViewer map frequently during data collecting; watch for:
Negative readings in the Shallow and Deep or excessive noise in the OpticMapper data.
Sensor readings should fluctuate gradually as you drive across the field, relating to

soil changes. If readings change erratically, or show values not typical of soil
in the area, perform tests 4-6 below.
In SoilViewer, watch for streaks, stripes, unnatural patterns, and missing data points.

4. Perform electrical continuity test on implement wiring:

at least once a day during mapping season
every 10 hours of mapping
after extended periods of non-use
after replacing or repairing coulter-electrode components or wiring
whenever readings are questionable

5. Perform Signal Testing Procedures #1 and #2:

at least once a day during mapping season
every 10 hours of mapping
after extended periods of non-use
whenever readings are questionable

6. Perform black/white reference OM System Check and OM Test Load Procedure #1

Before mapping every field
Whenever readings are questionable

7. Keep all electrical connections dirt and moisture-free

8. Limit speeds in rough or rocky field conditions. This will improve data quality, and will also

lengthen the service life of the implement components. NEVER EXCEED 15 M.P.H. FIELD
SPEED WHEN MAPPING EC/OM. NEVER EXCEED 7.5 M.P.H. WHEN MAPPING PH.

OM Data Quality

Check depth of sensor – Make a couple of trial passes to make sure the sensor is running at the
proper depth. Recommended depth is 2-3 inches.
Add weights or adjust down pressure on row unit if needed

Also make sure the row unit side depth wheels and disks are rotating freely, and are clear of
excess mud and crop residue.
For row unit adjustments see page 4-22.

Monitoring the window –Observe OM readings at row ends when unit is raised, if they are not
within 10% of the initial raised readings, check windows for mud, smearing, and/or window
breakage.

Varying Field Conditions – In order to have high data quality the field conditions need to be the
same for an entire data set. Any of the following can affect data quality: in-field soil temperature
and moisture difference, change in down pressure or depth gauge wheel setting. If conditions
change, start a new file.

Figure 66 is an example of how these items can affect data quality.

briefly. If water does not flow from jets within 10 seconds, disconnect quick couplers to help pumps

prime. If water doesn’t spray, but pump is running, see Troubleshooting section for instructions on

priming pump. If pumps don’t operate, recheck power cables and connections. If electrical power

to Controller is functioning, test hydraulics by locking hydraulic lever in position, and raising and
lowering sampler shoe using manual Up/Down switch. Test Raise/Lower functions on main lift
cylinder if equipped. Make sure no one is under unit and keep clear of any pinch points.

Figure 73
Note: if MSP is equipped with EC Module and EC data is being collected along with pH data,

adjusting the overall height of the unit will affect coulter-electrode depth. If deeper soil sampling is
desired, and shortening ratchet jack would result in excessive coulter-electrode depth, remove
sampler shank pins and lower shank to lowest setting. If shallower soil sampling is required, and
lengthen ratchet jack results in inadequate coulter-electrode depth for EC data collection, raise
sampler shank to highest setting.

speed signal for disengagement.

Before inspecting or working around any
component of the system, press the 1 key and

verify status of system is ‘Disengaged’ before

exiting the vehicle. Sporadic GPS signals may
simulate movement and initiate the cycling
process, resulting in possible entanglement and injury.

If TAP or DI are selected as the wash water type, the water baseline process will be repeated
every 40 cycles following the next engage press. If the pH during the cycling sequence does not
get within 0.5 of the baseline pH, an audible alarm will sound and the pH labels will blink. This is to
allow operator that the electrodes are not cleaning properly.

From this screen, pressing the Engage key or Enter as you drive forward will initiate the automatic

sampling process. The software requires movement indicated by the GPS receiver in order to
cycle. Speed must be detected within 5 seconds after pressing enter or the system will disengage.

If TAP or DI were selected as the wash water type above, the controller will go through a wash
baseline process after engage is pressed for the first time. The status text will change to the
following:

“Cycling” means the sampler assembly is in the process of washing, and lowering for soil sampling.

After a core has been collected and is being held against the electrodes, the status text will change
to the following:

Figure 101
The pH readings on the display show what each electrode is reading at every second. The

sampler will hold the soil against the electrodes and continue to record pH until the readings settle.
The minimum recording time is 7 seconds; the maximum time is determined in the pH settings
menu. The pH values that are recorded are the final values at the end of the logging duration. (last

reading on the display before the “Cycling” status appears). The final pH value is logged along

with the DGPS position where the sample was collected.
If the electrodes take longer than 10 seconds to settle, a warning will appear that indicates the

number of seconds the reading has required to settle. When the maximum log time is reached, the
unit initiates a new sample cycle (refer to Controller setup for adjusting the log time).

Figure 102
This time warning is to let the operator know that a measurement cycle is requiring excessive time.

While an occasional cycle may exhibit this warning; see the troubleshooting section if this occurs
frequently.

The Veris MSP pH Manager uses two electrodes for optimal data quality. If there is a difference of

0.75 or greater between the final electrode readings, the software will beep and the pH readings

will flash, informing the operator of the erroneous reading.
To pause the data collection process at any time (but keep the same file), press Engage button.
Once the sampling process has completed its cycle, it will disengage and the status text message
will indicate disengaged (press Engage to start cycling again). If the system no longer senses a
speed signal from the GPS, it will also disengage. NOTE: do not depend on the GPS speed signal
for disengagement.

Before inspecting or working around any
component of the system, press the Engage key
and ensure the engage light is red before exiting the
vehicle. Sporadic GPS signals may simulate
movement and initiate the cycling process,
resulting in possible entanglement and injury.

If TAP or DI are selected as the wash water type, the water baseline process will be repeated
every 40 cycles following the next engage press. If the pH during the cycling sequence does not
get within 0.5 of the baseline pH, the computer speakers will beep and the pH labels will blink. This
is to allow operator that the electrodes are not cleaning properly.

There are warning signals programmed into the SoilViewer to warn the operator that data are not

being recorded, so that corrective action can be taken. If data aren’t being recorded, a warning

beep will sound from the computer, and the text indicator of the data that is missing information will

blink. For example, if the DGPS isn’t being received (or the NMEA string containing speed) the Fix

indicator text will blink. If EC values are negative, they will also blink.

pH Data Flags

Numbered “flags” can be added to the pH data by pressing the Flag key or F2 while the pH

Manager is CYCLING or RECORDING. If the key is pressed while the pH Manager is in the
RECORDING phase, the flag light will turn bright green:

Figure 103
This means the flag will be recorded with the current data point. If the key is pressed while the pH

Manager is in the CYCLING phase, the next point will be flagged and flag light will not turn green
until the RECORDING phase is reached. Tip: Use this function to flag any sample where a problem

has occurred, such as a plugged shoe. Open the pH file in a spreadsheet program, locate the
points that have been flagged, and delete rows of problem data.

Setting Sensor Depth

Refer to Figure 7

The “T” handle (1) sets sensing depth by limiting the how
high the side depth gauge wheels ride relative to the
opener disks. To adjust sensing depth, pull the “T” handle
(1) up and back,move it forward or aft, and set it back in a
different pair of holes in the scale.

• For shallower sensing, move the “T” handle (1) forward.

• For deeper sensing, move the “T” handle (1) back.

Opener Disc Contact Region

Refer to Figure 8

Opener disc angle and stagger is not adjustable, but
disc-to-disc spacing is, and may need attention as discs
experience normal wear. Spacers will need to be reset
when blades are replaced.
The ideal spacing causes the blades to be in contact for
about one inch (4) . If you insert two pieces of paper
between the blades, they should slide to within zero
(touching) to 1.5in (3.8cm) of each other. If zero, the gap
between the blades should not be significantly greater
than the thickness of two sheets of paper.
If the contact region is significantly larger or there is a
large gap, it needs to be adjusted by moving one or more
spacer washers.

Adjusting Disc Contact

Refer to Figure 9

1. Raise the Implement.

2. Remove the side gauge wheels (5) on the row unit in
need of adjustment.

3. Remove the bolt (6) retaining the opener disc (7) on
one side. Carefully remove the disc. Do not lose the
hub components and spacer washers (8)(9).

4. To reduce the spacing between the discs (the normal
case), move one spacer washer from the inside (8) to
the outside (9) of the disc.

5. Re-assemble and check disk contact.

Figure 12

Refer to Figure 10 and Figure 11

Disc-to-wheel angle and clearance ideally has the wheel
just touching the disk when the wheel is raised to sensing
depth (is up against the stop set by the “T” handle.
The goal is to have both disks and wheels turn freely, but
keep soil and trash from getting between them.

These two adjustments interact with each other. Changing
one requires at least checking the other.

In addition to changing the disk angle due to changing
depth or new field conditions, these two settings may
need attention over time as the disk and wheels wear
from normal use. This adjustment will also need to be
made if any opener components are replaced.

Refer to Figure 11

For 2in (5.1cm) sensing depth, adjust side gauge wheel
angle so wheels contact row unit disks at the bottom of
wheel. Check with row units in soil so wheels are held
up.

At the same time, keep side gauge wheels close to
opener disks so openers do not plug with soil or trash.

Note: Wheels should be out far enough so disks and
wheels turn freely.

Refer to Figure 13 on page 5-5

To adjust side gauge wheels:

1. Raise the implement.

2. Loosen hex-head bolt (1) . Move wheel and arm out
on O-ring bushing.

3. Loosen pivot bolt (2) Turn hex adjuster (2) so
Indicator notch (4) is at 5 o’clock to 7 o’clock.
Note: Use this as the starting point for adjustment.

4. Move wheel arm in so side gauge wheel contacts
row unit disk. Tighten hex-head bolt (1) to clamp arm
around bushing and shank.

Refer to Figure 12

5. Check wheel-to-disk contact at 2in (5.2cm) sensing
depth. Lift wheel 2in, check contact and release.
When let go, wheel should fall freely.

• If wheel does not contact disk at bottom to area where
blade leaves contact with soil, move hex adjuster until

wheel is angled for proper contact with disk.

Pub. #OM17-MSP3

and slide wheel arm out just until wheel and arm move
freely. Retighten hex-head bolt (1) according to grade:
1⁄2in Grade 5 bolt on 25 series, 75 ft-lbs (102 N-m).
1⁄2in Grade 8 bolt on 25 series, 110 ft-lbs (149 N-m).

6. Keep turning hex adjuster and moving wheel arm
until the wheel is adjusted properly. When satisfied,
tighten pivot bolt (2) to 110 ft-lbs (149 N-m).

Adjusting Gauge Wheel Scrapers

Refer to Figure 14 (bottom view)

Scrapers are optional, and may be useful in moist or
sticky soils that tend to accumulate on gauge wheels
and reduce intended sensing depth.

To adjust scrapers:

1. Loosen nut (5).

2. Slide scraper (6) toward gauge wheel (8) until
scraper touches tire.

3. Slide scraper (6) away from wheel (8) leaving a
1⁄8in (3mm) gap at (7) .

4. Rotate scraper left and right around bolt, making
sure it cannot touch tire if bumped in field. If it can
touch tire, back scraper away from wheel until it cannot.

5. Center scraper angle on bolt (5) until gap (7) is constant.

6. Tighten nut (5).

Procedure #3: Testing Electrical Continuity

Perform this test daily or every 10 hours of data collection to ensure you are obtaining reliable
data, and whenever EC data is questionable.

The purpose of this test is to insure that each coulter-electrode has an uninterrupted signal path
from the EC Surveyor to the disk blade. Think of each coulter-electrode and its wire path as a

‘channel’. On a 3100 and 3150, there are 6 signal channels that must be clear and isolated from

each other (4 on a 2000XA). You will first test the complete pathway for each channel—each
coulter-electrode. One easy-to-take reading for each channel tests the cable, wiring harness, and
each coulter-electrode and disk blade. If no problems surface during this test, there is no need to
test individual components. This test should take only a couple of minutes to perform.

To perform this test, you will need the EC Signal Test Box (part #49708) and an ohmmeter
(sometimes referred to as a multi-meter or voltmeter). Make sure the meter is set to ohms, Ω. If a
range of ohms is available, choose the lowest setting--ohms rather than kilo or mega ohms. If
unfamiliar with ‘ohming-out’ or resistance testing, make a few trial tests before performing the Veris
signal test procedure. Touching the meter leads together will display a zero resistance reading,
touching two places on the same piece of metal will produce a nearly zero reading, touching
nothing will produce an OL (overload or over limit) reading—meaning complete resistance, and no
continuity.

Figure 3.1 Figure 3.2
Remove the signal cable from the EC Surveyor and connect it to the terminal on the test box. If

you have hard-wired the signal cable extension into the cab, making it difficult to reach the
implement with the cable end, you may want to purchase an extension cable from Veris (part
#12269). This cable attaches to the signal cable end and allows you to position the Signal Test
Box in close proximity to the coulter-electrodes.

back and forth as you view the ohmmeter. Any jump in the readings above 2 ohms indicates a
problem.

Continue to check each coulter electrode in succession, left to right.

#4 Diagnosing EC Signal Problems.

Coulter Electrode Functions-

Each coulter electrode on the implement is part of a pair, and each pair has a distinct function.

a) Coulters 1 & 6 are the Deep EC receptors. If you are seeing problems only with the “Deep”

readings, focus on testing continuity on these two coulter-electrodes.

b) Coulters 2 & 5 are the “charged” coulters that inject the voltage into the soil. If you are

getting no (or intermittent) readings on both the “Shallow” and the “Deep” -- continuity to
one of these two coulter-electrodes is likely the cause.

c) Coulters 3 & 4 are the “Shallow EC” receptors. Focus on this pair if you see problems in the

“Shallow” reading.

If the continuity ohm test indicates a problem on a channel, you will need to determine where the
interruption is located. Listed below are detailed instructions on how to determine exactly where a
continuity or isolation problem is located:

A. Testing Cable and Wiring continuity:

1. Once a high resistance reading on a channel is confirmed, determine whether the problem
is in the wiring or in the coulter-electrode. To test all cable and wiring, place one ohmmeter
lead in the Test Box terminal pin for that channel and the other on the corresponding coulter
wire terminal bolt. Grasp sure-seal connector and move back and forth during this test –
vibration from rough fields can weaken the contacts on the sure seal, causing breaks in
continuity during operation that might no show up in a static test. Repeat process on all
coulter-electrodes.

Figure 4.2 Testing cable at coulter electrode #3 terminal

2. If you see <2 ohms on all, test the coulter electrodes as explained in B below.

3. If you see a > 2ohms reading on any channel, separate sure-seal connector and insert one
ohmmeter lead in the end of wiring harness and the other lead in the corresponding terminal
on the Test Box. If reading is < 2 ohms at that point, the problem is not with the wiring
harness or signal cable extension. It is most likely in the terminal connector wire. Check
resistance in it by placing one ohmmeter lead on the coulter wire terminal bolt and the other
lead in the end of the terminal wire socket. Replace connector wire (PN 14226) as
necessary.

6-7

Pub. #OM17-MSP3

Figure 4.3 Testing cable at end of signal cable wiring harness

Figures 4.4 ab. a. Separating sure-seal connector b. Testing terminal connector wire

4. If there is a >2 ohm reading in the signal cable harness or signal extension cable, visually
inspect the wiring harness and cable extension for damage. If a visual inspection doesn’t
reveal a problem, you will need to test continuity of the wiring harness and cable. You will
need to ohm these cables out individually. Disconnect signal extension cable from
implement and insert ohmmeter leads into sockets as shown below.

Figures 4.5 a and b. Checking continuity of signal extension cable with one ohmmeter lead
contacting pins in extension cable end, and other lead contacting corresponding test box terminal.

6-8

Pub. #OM17-MSP3

5. To ohm out the wiring harness, disconnect the serial cable extension from the implement
and check continuity through the harness as shown in Figures 10a and 10b. While doing so,
check the pins and the sockets of the 6-pin connector for corrosion and fit. If necessary
spread the pins with a small screwdriver to tighten fit in sockets.

Figures 4.6 a and b. Checking continuity of signal harness, with one ohmmeter lead contacting
pins in connector and other lead contacting corresponding coulter-electrode.

Note: intermittent electrical problems are difficult to diagnose. Flex wiring and connectors while
checking continuity.

B. Testing Coulter-Electrode continuity

1. Place ohmmeter lead on terminal wire bolt and other lead on disk blade. Rotate blade ¼
turn. If readings are consistently above 2 ohms, check for excessive corrosion at the coulter
blade mounting bolts, or the terminal located near the coulter pivot. Make sure that high
ohm readings are not due to poor contact between blade and ohmmeter lead. Re-test
holding lead firmly against edge of blade, removing rust or paint if necessary.

2. If ohms jump over 2 ohms when the blade is rotated, and you were careful to maintain good
contact between the lead and the blade, the problem is likely inside the hub. Because
electrical signals cannot be sent consistently through the coulter bearing, Veris has
designed a more reliable path for the EC signal to travel. A special hub with a spring plunger
presses against the spindle of the coulter, serving as a commutator. Shown below is a cut­away view of the hubcap and plunger assembly. When ohm readings jump during blade
rotation, it is due to the greased rollers on the bearing making intermittent and inconsistent
contact. See Maintenance and Service procedure #4: Spring Plunger adjustment and
replacement on adjusting and replacing spring plungers.

C. Testing Coulter-Electrode isolation
If continuity tests show no excessive resistance on any channel, yet erratic soil EC readings

continue, or if EC readings do not drop to –1 when unit is out of the soil, it is possible that the
channels are not isolated. This could be the result of a pinched wiring cable, causing channels to
short out. Or, one of the coulter-electrodes is no longer insulated properly from the frame or
adjacent coulter-electrodes.

1. If EC readings do not drop to –1 when unit is raised, disconnect signal cable extension from
implement. If readings don’t drop to –1, the problem is with the signal cable extension. If
readings show -1, re-insert the signal cable extension into the implement. Disconnect the
sure-seal terminal connector wire from each coulter electrode. If readings don’t drop to –1,
the problem is with the wiring harness. If this is the case, you should replace the wiring
harness. If readings do drop, re-insert the signal cable extension into the implement. The
problem is with one or more of the coulter-electrodes. Proceed as follows:

2. Inspect nylon insulation slides under coulter­electrode mounting brackets. These nylon insulators
may become worn or brittle, or may slip out from
under mounting bracket. Repair and replace as
necessary. Make sure that all electrode coulter U­bolts are properly tightened to clamp mounting
bracket and insulation tightly to frame.

Figure 4.9

3. Disconnect signal cable from instrument or front of frame. Check so see that no metal part
of the any coulter electrode is in contact with the implement frame. This may be by visual
inspection or by connecting one lead of an ohmmeter to the individual coulter electrode, and
the other to a grounded fastener on the frame. If the coulter electrode is properly isolated,
no reading will be obtained. Make sure that all electrode coulter clamp bolts are properly
tightened to prevent lateral movement of the coulter electrode.

Figures 4.10 a and b

4. Wet soil on the toolbar could be a pathway for the EC signal to short. Test coulter-to-coulter
and coulter-to-frame isolation by checking resistance between coulter-electrodes. Any
continuity from one coulter to another is not acceptable. Remove buildup of wet soil,
especially if is bridges across insulation slides. It may be necessary to remove coulter
mounting brackets and clean toolbar, if problem persists.

signal to short.

Procedure #5 Spring Plunger adjustment and replacement

The spring plungers are located in the center of each coulter electrode hub cap, and are vital to
maintain good continuity through the coulter hub bearings. They are factory preset, and should
not need routine adjustment. If a continuity test shows abnormally high resistance, the plungers
should be checked. This may be performed in the following manner:

1) Check coulter hub bearing preload by grasping coulter blade and pushing
from side to side. If there is any noticeable movement, bearing preload is
incorrect, or bearings are failing --and this can damage the spring plunger ;
see procedure #8 for adjustment or replacement.

2) Remove the 3/8” allen head set screw.

3) Remove the plunger by turning counter-clockwise.

4) Depress the spring loaded tip on a hard surface to determine if

plunger has adequate tension and can move freely.

5) If the plunger will not move freely, replace. Coat the threads with di-electric
silicone grease before installation.

6) If the plunger appears to be in good working order, reinstall in the hub, and
adjust until it bottoms against the spindle end. Rotate 1/2 turn backward to
allow adequate clearance. Improper adjustment will result in premature
failure (too little tolerance) or poor continuity (too much tolerance). See
Figure 5.1 below to view proper clearance.

7) Reinstall locking set screw and tighten firmly on top of plunger. The top of
the setscrew should be even with the face of the hub. If not, remove and
adjust the plunger inward or outward as necessary.

8) Re-test coulter electrode continuity

Figure 5.1
In some cases, you may have to remove the hub cap to service the spring plunger, if the

plunger is rusted in the cap, or if the readings are still unsatisfactory with the new plunger
installed.

Procedure:

1) Remove hub cap by turning clockwise with a pipe wrench or large
adjustable wrench – these caps have left hand thread to prevent loosening
during field rotation.

2) If plunger is frozen in cap, remove allen head set screw on top of plunger
and apply penetrating oil on both sides of plunger. Let this stand for a few
minutes and try to remove. If it will not back out with allen wrench, lock
vise grips on the inside portion and turn out through inside of hub.

3) Clean all hub cap surfaces, install new o-ring, coat plunger and set screw
with di-electric grease and install as outlined above.

4) At the same time, inspect the end of the spindle. Over time the plunger will
wear a slight depression in the spindle face. This is common, and more
noticeable on high acreage units, or units that have been operated at high

field speeds. If the depression is 1/6” or more, carefully grind the face of

the spindle. Cover the bearing with a cloth or towel to prevent grinding dust
from entering the hub and bearings..

5) Re-install hub cap and tighten firmly. You may have to re-set the plunger
to compensate for the reduced length on the newly ground spindle. Re­adjust as outlined above.

Note: If you are still unable to obtain favorable resistance readings, check for excessive corrosion
at the coulter blade mounting bolts, or the terminal located near the coulter pivot. It may be
necessary to grind the spindle end smooth, if a dimple has developed.

Procedure #6: Diagnosing GPS-related problems

If you do not see a GPS, DGPS, or RTK in the upper left-hand corner of the EC Surveyor screen,
you do not have GPS coming in, and no data will be sent out the serial port for logging.

Figure 6.1
Insure your GPS receiver is powered and outputting only two NMEA strings GGA, and either

VTG or RMC at a 1hz rate; 4800 baud, 8 data bits, no parity, 1 stop bit. Verify that your GPS cable
is sending GPS data through pin 2, pin 5 is ground, and no other pins have signal or power on
them. The most common issue is hz rate. If the GPS has been used for lightbar guidance it may
have been set to a 5 or 10 hz rate. It will need to be changed to 1 hz in order for the
OpticMapper/EC controller to accept it.

Shown below is a Troubleshooting tree for diagnosing GPS signal problems. It is not meant to
replace your GPS receiver user manual—it merely shows how to determine if your receiver is
sending the GPS signal that the EC Surveyor needs.

Figure 6.2

If it becomes necessary to send GPS data into your PC, you will use a program called
HyperTerminal. This program is in all Windows software. It is designed to record serial data
streaming into a serial or USB port on the computer. The purpose of this is two-fold: 1) it verifies
whether your GPS and cables are delivering the proper messages, and 2) it give Veris
Technologies support personnel a GPS data file to test.

Here’s how to use HyperTerminal

1. Plug the GPS output cable into the laptop serial input (or USB-serial hub); no null modem is
needed

2. Verify in Device Manager which Com port the GPS is connected to (Start--Settings—Control
Panel—System—Hardware—Device Manager—Ports

3. Start the “HyperTerminal” program under “Accessories” in Windows.

Figure 6.3

4. Give your HyperTerminal session a name such as gps trial when the program prompts you
for the name of your connection and then hit “OK”.

Figure 6.4

6-15

Pub. #OM17-MSP3

5. The program will then ask you for a phone number. Instead of entering a phone number,
specify the proper serial port number. For example, if Com 1 of the laptop is being used,
specify “Direct to Com 1” under “connect using:” at the bottom of the entry area.

Figure 6.5

6. HyperTerminal will then display a configuration menu where you can specify 4800 bits per
second, 8 data bits, no parity, 1 stop bit and no flow control.

Figure 6.6

6-16

Pub. #OM17-MSP3

7. At this point, upon clicking ok, legible strings of GPS data should begin appearing on the
laptop screen. Here’s an example of a typical set of strings:

$GPGGA,191528.00,3851.0333,N,09737.2342,W,2,08,1.3,372.7,M,27.3,M,10.0,0100*69
$GPRMC,191528.00,A,3851.0333,N,09737.2342,W,0.1,0.0,090998,6.3,E*48

8. If GPS data doesn’t appear, recheck the port and configuration settings to make sure they

are correct. If the data won’t appear correctly in HyperTerminal, consult your GPS supplier

to see what adjustments (connectors or software) are necessary to bring the signal into a
computer.

9. If the signal appears correctly on HyperTerminal and it shows that the required strings are
being output, highlight a page of strings, copy and paste into Word or Wordpad before
exiting HyperTerminal.

10. Retry the unit with the Veris instrument. If it still doesn’t work, please email the page of GPS
strings from HyperTerminal to [e-mail], along with your contact information.

Procedure #8: Bearing Repair and Replacement

The coulter electrode hubs operate in a significantly harsh environment, and annual inspection is
of utmost importance. The double-lip seals are designed to keep grease in, and contaminates out,
but they are the cause of practically all hub failures. It is advisable to disassemble, clean and
repair annually. To perform this maintenance, do the following:

1) Remove hub cap by turning in a clockwise direction (left-hand thread
prevents loosening in operation).

2) Remove cotter pin, castle nut, thrust washer, and remove hub.

3) Remove outer bearing and knock out inner bearing and both races (cups)

4) Veris recommends that you purchase our Coulter Hub Repair Kit (PN

32641) that includes new bearings, races, seal, o-ring and cotter pin.

5) Thoroughly wash hub in solvent and dry.

6) Spindle end may need grinding—see spring plunger replacement
Procedure #4

7) Reassemble and adjust bearing pre-load by fully tightening spindle nut,
then backing off until you can turn the hub fairly easily with one hand–
normally this involves backing off 1- 2 slots on the castle nut, and
inserting cotter pin. Excessive pre-load may cause plugging in extremely
loose soil conditions, and excessive endplay may damage the spring
plunger. Hub should have no side play when assembled, but should turn
with little resistance. Drive round end of cotter pin firmly into nut, and bend
upper portion of cotter pin upward and trim of excess length of both top and
bottom with cutting pliers. Do not bend cotter pin over the end of
spindle as it will interfere with spring plunger.

8) Fill hub via grease zerk until grease pushes through outer bearing.

9) Install hub cap by threading counter-clockwise on the hub. Check to make
sure that hub still rotates freely. If not, the cotter pin may too long, and is
contacting hubcap –remove cap and check cotter pin length.

10) Adjust spring plunger clearance as mentioned in Procedure #5.

Use pH simulator to test external controller and Veris
instrument.

On/Off key (Turn pH simulator OFF when test is completed)
Attach to each BNC port to test each circuit
Press Select button to toggle from 4 to 7 to 10. Light above pH

value will light. View Veris display to confirm these readings
at each simulator setting:
4 should read -2, 7 should read .6, and 10 should read 3.9.
(Note: the simulator is designed for glass electrodes; for

antimony the readings are those listed above)

2. Wash system malfunctioning: no water being pumped

-are there at least 10 gallons of water in tank?

-are pumps running? If not, check electrical connections and 12 volt power to them

-check pressure switch on pump—wiggle wire, disconnect and reconnect; direct wire if needed

-is filter plugged?

-is ball valve open?

-disconnect quick couplers to help pumps prime

3. pH readings seem erroneous or won’t calibrate

-Use pH simulator to test External Controller and Veris instrument. Re-test with pH simulator
set to High Impedance

Figure 11.5

-check for moisture around BNC connectors and for proper installation and fit of the BNC cover
over BNC connections (if the pH simulator readings are not close to the default settings, blow
compressed air into BNC ports on external control module)

4. Sampling shoe plugging

-verify if shoe is plugged: wash electrodes to create a wet sample in the shoe; in manual mode
lower sampler to full depth and drive forward; if soil in the sampling trough is now dry, fresh soil
has entered and the shoe isn’t plugged

-to clean plugged shoe, raise implement, lower shoe manually to maximum depth, and drive

forward at high rate of speed as you lower the implement completely; if it doesn’t clear, clean

manually (put transport locks in before working under unit)

-clean cutting shoe thoroughly, especially if it has dried mud in it

-check cutting shoe and scraper for wear; replace as needed

-check scraper adjustment by manually raising and lowering sampler assembly. Does scraper
completely clean the cutting shoe face? See Field Operation section for proper adjustment

-adjust row cleaner to clear residue more completely

-adjust firming wheel down to firm soil

-lower sampling depth to engage soil with better coring properties

5. pH readings are repeatedly >.5 different or are slow to settle,

-check shoe for sample quality. If only a small amount of soil is present, reduce field speed to
retain adequate core. If crop residue is present, adjust cleaning disks to reduce crop residue in
sampling area.
