Setting Operating Depth
Begin field operation by lowering unit into soil. For good electrical conductivity, all disk electrodes
must be in direct contact with moist soil, at all times and in every region of the field. A depth of 1-
2”
(2.5-5 cm) is recommended (Figure 13). To insure this depth is consistently achieved, 400 lbs (180
kg) of additional weight are normally required. Veris offers optional weights, or they can be
supplied by the customer. Lower unit until proper disk depth is achieved, or until wheels are
slightly (<.5 inch/ 1 cm) off the ground.

Field Condition
Field should be in a uniform state. Mapping after intensive primary tillage is not recommended. The
soil must have a minimum of 20% available water, and cannot be frozen. If rocky conditions exist,
slow down.
Speed
Proper field operating speed depends on field conditions. Because of the importance of consistent
contact, the unit must not be allowed to bounce over rough fields at high speeds.
• Be very careful when mapping stubble fields using a vehicle with a gasoline engine. Be prepared
if a fire starts. Keep crop residue and other debris from accumulating near the exhaust and in
engine compartment.
