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
