Ec Signal Testing - Veris 3150 MSP3 Operating Instructions Manual

Procedure #2: EC 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 VSense 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:
7) Disconnect the signal cable from the signal terminal on the OpticMapper/EC controller.
8) Connect the test load to the signal terminal.
9) Switch on the VSense controller and view display in SoilViewer or Data.
10) The display should show::
MSP3
0-1: 11
0-3: 40
11) If the readings vary significantly (more than one whole number) contact Veris service
department.
12) Once the test is complete, remove the test load and reinstall the implement signal cable.
