Checking Electrical Signal Continuity and Electrode Isolation
It is recommended that you routinely check the EC signal to verify that all functions are
working properly. See Maintenance and Lubrication Section for a step-by-step
procedure. It is advisable to perform this test on a routine basis (weekly or every 20-25
hours of data collection) to ensure you are obtaining reliable data.
Setting Operating Depth
Begin field operation by lowering unit into soil. For good electrical conductivity, all
coulter electrodes must be in direct contact with the soil, at all times and in every region
of the field. A depth of 1-
2” (2.5-5 cm) is recommended. To insure this depth is
consistently achieved, 400-600 lbs. (180-275 kg) of additional weight are normally
required. Veris offers optional weights, or they can be supplied by the customer. Do
not adjust the tension on the coulter electrode springs to increase soil contact or
penetration. They are pre-set at the factory with the proper tension.

Field Condition
Field should be in a uniform state. Mapping after intensive primary tillage is not
recommended. The soil must have a minimum of 10% available water, and cannot be
frozen. If rocky conditions exist, you may wish to consider the optional coulter rock
guard kit, PN 15169.
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.
Pulling Vehicle
The implement may be pulled with a variety of vehicles: 20-50 hp tractor, 4WD pickup
or Jeep.
