Procedure #2: EC Signal Testing
Perform this test monthly or every 100 hours of data collection and whenever EC data is questionable.
The purpose of this test is to ensure the instrument is performing properly.
The V-Sense Controller is shipped with an Instrument Test Load (Part No. 223640) that will enable you to
quickly check the instrument to ensure that it is functioning properly. To perform this test:
1) Disconnect the signal cable from the signal terminal on the V-Sense controller.
2) Connect the test load to the signal terminal.
3) Switch on the V-Sense controller and view display in SoilViewer or Data. The EC display should
show: 50
4) If the readings vary significantly (more than five) contact Veris service department.
5) Once the test is complete, remove the test load and reinstall the implement signal cable.
