Insert a disk, then press any key. The display will read “Working”, which means the system is
checking out your disk to see if you have enough disk space to accept the file. If you do not have
enough space, it will ask you to insert a different disk.
During the download process, the instrument will display what file it is currently downloading and its
progress:
Once the system has begun downloading the files, do not remove the disk or shut the power
off until the file is completely downloaded
The system has finished downloading to your disk and is ready for the next step. Press any key to
bring up next display.
If you press #3, the instrument will index to the next file and offer the same options. If no files are left
to download, you will then go to the main menu.
About the Veris EC output file format: Veris EC data is output as a 5 column ASCII text file.
Column A: longitude, B: latitude, C: EC Shallow Array (mS/m), D: EC Deep Array (mS/m), E: DGPS
elevation (meters):
Long. Lat. E.C. Shallow E.C. Deep Elevation
-88.7579 43.49488 2.2 5.9 291.2
About the Veris pH output file formats: 3 files are created during pH data acquisition: one
containing the raw millivolt readings of the electrodes in soil (VPHL000.DAT), one containing the
millivolt readings of the electrodes during the wash sequence (VPHW000.DAT), and one containing
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
