Procedure #1: EC Surveyor Instrument Signal Testing
Perform this test daily or every 10 hours of data collection to ensure you are obtaining reliable
data, and whenever EC data is questionable. The purpose of this test is to insure that the
instrument is performing properly.
The EC Surveyor is shipped with an Instrument Test Load (Part No. 10447) 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 EC Surveyor.
2) Connect the test load to the signal terminal.
3) Switch on the EC Surveyor and view display.
4) The display should show:
Shallow:
(2000XA and 3100) 14 (3150) 11
Deep: (2000XA and 3100) 21 (3150) 40
5) If the readings vary significantly (more than one whole number) contact Veris service
department.
6) Once the test is complete, remove the test load and reinstall the implement signal cable.
