Figure 16-1. Calibration disk
When you have entered the calibrator information the sensor will wait for you
to place the foam bungs into the sensor hoods. The bungs are designed to block
all light from the outside reaching inside the head. Place one bung into each
hood. If either of the bungs are damaged or appear to have any gaps around the
edge please contact Campbell Scientific.
This part of the test will take approximately two minutes. Every ten seconds a
dot should appear indicating that the test is progressing as normal.
Remove the bungs once the sensor instructs you to. Place the sensor calibrator
into the volume by fastening it to the central mounting point.
At this stage it is advisable to perform a simple visual check of the
cleanliness of the calibration plate. If contaminated clean it on

NOTE
Starting dark level calibration.
This test will take approximately two minutes.
Dark level test complete. Please remove the bungs.
Now place the sensor calibrator into the sampling
