Pub. #OM MSP03-1

the final settled smoothed soil pH readings (VPHE000.DAT). A formatting example of each file type

follows:

Raw soil millivolts (VPHLXXX.DAT):

Long. Lat. Electrode 1 (mV) Electrode 2 (mV) Elevation Speed

-88.7579 43.49488 -20 -25 291.2 4.5

Wash sequence millivolts (VPHWXXX.DAT):

Long. Lat. Electrode 1 (mV) Electrode 2 (mV) Controller state

-88.7579 43.49488 -20 -25 33

Extracted soil pH (VPHEXXX.DAT):

LONGITUDE LATITUDE pH TIME ALTITUDE SPEED

-88.7579 43.49488 6.75 8.5 291.2 4.5

The extracted file also contains 5 columns of file statistics at its end offset from the normal data:

accepted rejected settling range difference

216 1 0 5

The extracted pH file contains the coordinates of the reading’s location, the settled, averaged pH

reading, the time the reading took to settle, the readings’ elevation, and the speed the vehicle was

moving at the time the sample was taken. The statistics at the end of the file break down how many

points were considered “good” by the extraction routine and how many were rejected and the reason

for rejection. A point can be rejected for 3 reasons: 1. The readings did not settle in the maximum

time allowed; 2. The readings were outside of a reasonable pH range (less than 3.5 or greater than

9.5); or 3. There was more than a 0.5 pH difference between the electrodes.

INSTRUCTIONS ON DOWNLOADING DATA

Clean-up—ISE storage, wash

If you are going to interrupt your pH mapping for 30 minutes or longer, clean off the electrodes and

the electrode holder with the wash wand, and install the soaker solution container on the electrode

holder. Replace soaker solution (Veris part #23395) weekly, or more frequently if it is diluted or dirty.

Maintenance and Lubrication

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

MSP. Disengage automatic cycling function before working around unit. Install all transport locks

before transporting or working underneath.
