Procedure #1: OM 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 OpticMapper/EC Controller is shipped with an Instrument Test Load (Part No. 46403) that
will enable you to quickly check the instrument to ensure that it is functioning properly. To perform
this test:
1) Disconnect the optical power cable from the OpticMapper/EC Controller.
2) Connect the test load to the Optical Power port.
3) Switch on the OpticMapper and view display on SoilViewer or Datalogger.
4) The display should show:
Red: 833 +/-10
IR: 289+/-10
5) If the readings vary significantly contact Veris service department.
6) Once the test is complete, remove the test load and reinstall the optical power cable.
