Speed
Probe speed is not recommended over 30mm/sec, for optimal data resolution. This is
adjustable via the probe speed flow control on the side of the control panel. (Figure 9
above) A maximum probe speed of 50mm/sec should not be exceeded or else data
could be missing from the output file.
Field Condition
Field should be in a uniform state. Probe after intensive primary tillage is not
recommended. The soil must have a minimum of 10% available water, and cannot be
frozen.
Vehicle Requirements
The probe may be mounted on a variety of vehicles. The 3 point configuration allows
use on a 30-50hp tractor. While the optional skid platform requires a 4X4 pickup.
Operational tips
• Observe probe closely while inserting. In hard soil the probe may deflect slightly;
stop inserting if it begins to bend or if it encounters a solid object.
• Use side-shift function to move probe to adjacent probing locations.
• Do not let stringpot cable snap back into spool; factory stringpot repair will
be required if cable retracts too rapidly.
• For best results, clear plant residue from probe insertion area.
