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.
