Checking Electrical Signal Continuity and Electrode Isolation

It is recommended that you perform the Electrical Signal Continuity and Electrode Isolation test
procedure before first field use (see Maintenance and Service Procedures 2 and 3). While these
tests were made at the factory, there is the possibility a problem developed during shipping.
Performing these tests on the new implement before it becomes dirty, allows you to get familiar
with the process under ideal conditions. It is strongly advised that you perform this test on a routine
basis (every 10 hours of data collection) to ensure you are obtaining reliable data. KEEP
OHMMETER, TEST LOAD AND TEST BOX WITH THE MACHINE AT ALL TIMES.

Setting Operating Depth

Begin field operation by lowering unit into soil. For good electrical conductivity, all coulter
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. To insure this depth is consistently achieved, 400-600
lbs. (180-275 kg) of additional weight are normally required. Carrying water in the pH wash tank
can aid penetration. Also, 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.

Depth Sensor

The depth sensor allows the operator to track the
mapping depth of the OpticMapper sensor.
If the depth is not consistent the data quality can be
affected. (Figure 23)
