SoilViewer OM System Check
The OM System check ensures the optical sensor and controller are functioning properly. By using
the light and dark reference block the range of the sensor can be determined. For proper
operation the range from the dark to light side for the red and IR readings must be at least 100. If
it is not that may indicate a broken wearplate, inadequte power, or damaged sensor. Run the
system check before mapping each field to ensure proper operation. The results of the system
check are stored in a .inf file specific for each field.
Select OM under the Sensor Checks drop down to start system
check.
