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 high-pressure
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

Electronics Overview and Set-up
The U3 electronics kit includes the items shown below
Keep all diagnostics and operations manual with system when mapping.
The supplied GPS (Figure 2a or 2b) is configured to
operate with the U3 electronics. Note: V.Sense
controllers manufactured before 9/01/2016 are equipped
with the external GPS shown in Figure 2a.
The use of any other GPS requires the correct settings. The
GPS needs to output only two NEMA strings(GGA and VTG
OR RMC). The system will not run with more than two
strings. The strings need to output at 4800 baud and 1Hz

Electronic Configurations
The U3 platform is comprised of two controllers: V.Sense and U3 pH The V.Sense controller generates the
EC and Optical signals, and communicates with the U3 pH controller, and the PC (SoilViewer software)
either via serial or Bluetooth. The SoilViewer software reads the status of the GPS and U3 pH controller
signal inputs (ex. up or down proximity sensors), and initiates the pH cycling when the cycle criteria are met.

Electro-hydraulic lift operation
1) The remote control offers simple operation of the power unit. Push button to raise and lower. Route to
prevent damage of cable. Be sure to lower the unit only as deep as needed to obtain proper penetration
of all 4 coulters.
2) Use depth collars provided to set desired operational depth. (Figure 4)
3) Prior to transport, always install the transport lock channel on the cylinder rod. (Figure 5)
4) Periodically check the fluid level of the reservoir with the implement in the lowered position. It should be
approximately 2” from top of reservoir, with the cylinder rod in the retracted position. Unit is filled with
Mobil 424 hydraulic fluid, and should be filled with compatible fluids of viscosity index between 100 and
400 ssu.

The SoilViewer mapping software will automatically detect the Bluetooth or Serial port the controller is
connected to, and begin communicating. If the V.Sense controller is not detected, the software will wait 45
seconds for the connection of the electronics and search again; this will repeat until the connection is
established. If the connection is not found, unplug the serial or USB cable, restart the PC, reboot the
controllers, then and reconnect USB cable to the PC. If using Bluetooth, exit the software, and ensure the
controller is paired per procedure 11.
The conditions for mapping and storing EC and Optical data are as follows. The unit must be traveling a
speed greater than 1 mph, there must be a GPS signal received, the OM/EC Comm Light must be green,
indicating the PC and V.Sense controller are communicating properly, and the EC 0-2 value has to be
greater than -1. When all these conditions are met, the Saving Data light will be green and the EC and
Optical points will be mapped.
The pH readings on the display show continuously what each electrode is reading. When logging sensor
data, the hydraulic cylinder will hold the electrodes against the soil and record a pH reading once a
particular settle method (see settle method criteria) has been met. The minimum recording time is 7
seconds; the maximum time (default 12 seconds) is determined in the pH controller settings menu. If the
reading takes 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 hydraulic cylinder will
automatically retract and wash the electrodes. For additional information on the pH sampling sequence see
the Recording UTV pH Data section.
Before mapping, perform the OM and pH system checks to ensure proper sensor operation.
If mapping has stopped, files may be appended by selecting a previous file when prompted at the startup of
the software.

These indicators help the operator know
when it’s time to stop for a pH sample.
These lights indicate when the operator is
within 30%,15%, and 5% of their
designated target sampling distance. The
target sampling distance can be set in the
pH Controller Settings menu. The default
value is 65 meters, which equates to about
1 point per acre.

2) Positive EC Values (unit in ground) and Speed equal to 0 and GPS quality greater or equal to 1
Single pH sample will complete one complete pH cycle. Automatic pH will cycle every time the above
criteria are met, and the minimum distance from the previous sample (default 10 meters). This minimum
distance setting is adjustable via the pH controller settings in the menu. Automatic mode allows the
operator to traverse the field, and cycles the pH when the implement is stopped for maximum efficiency.

The pH Cycle State indicator will alert the operator to the current state of the pH sequence. In addition, the
indicator lights on the screen will show the state of the controller input and outputs. The information
provided in these steps is for reference only, once the conditions for starting the pH cycle have been met,
the following sequence will automatically take place.
1) Rinse electrodes for 1 second. This clears any dust that has built up on the electrode while
traversing the field. When in automatic mode, the software anticipates a slowdown, and will
automatically pre-rinse the electrodes.

Settle Method Criteria
The electrodes are pre rinsed with water before cycling into the soil. This removes any dust which may
have built up on the electrodes, and establishes moisture for the pH sensor to properly function. A
measurement time of 7-15 seconds is required to allow the pH reading to move from the water pH to a
stabilized soil pH reading. The following settling methods are employed to allow the pH cycle to as quickly
as possible; while also alerting the user to potential issues.
Quick Settle (QS): Electrodes met a superior settle criterion in 8 seconds or less. The reading is stored,
and the cycle continues.
Standard Settle (S): Electrodes met standard settle criteria in less than the maximum settle time (default
12 seconds). The settled reading is recorded in the data file, and the cycle continues.
Time Out (TO): Electrodes didn’t settle within the maximum settle time. The reading was recorded;
however, one or both the electrodes didn’t meet the standard settle criteria. If 40% of your sensor data falls
in the category, consider increasing your maximum settle time.
Time Out Redo (TORD): Electrodes took longer than the maximum settle time, and the reading had
excessive noise. The software will prompt the user to pull forward 10 feet and redo the sample. No data
point will be logged in file.

This example shows the pH sampling pattern on a 200’ by 200’ (61 m) grid, which is slightly denser than a 1
acre (.4 ha) grid. The EC-OM transects are 50 ft (15 m) apart and the pH samples are collected from every
fourth transect.
Wash Time –Amount of time wash water sprays
the electrodes at the end of a pH cycle. Default is 1
second. If issues arise with electrode cleaning in
sticky soils, increase to 2 or 3 seconds)
Max Measurement time –Maximum time for
electrodes to record before rejecting sample. The
range of this value can be 12-20 seconds. Default
is 12 seconds. If over 30% of readings time out
before settling, increase time to 15-18 seconds.
Min Distance between samples -- This sets he
minimum sampling density in automatic mode. This
threshold keeps the sampler from cycling close to
an existing pH sample point. Default is 10 meters.
Target distance between samples (m) –Distance
at which the software will flag the operator to stop
and take a sample in Automatic mode. Default is
65 meters, which equates to about 1 point per acre.
