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 CS125 calibrator
into the volume by fastening it to the central mounting point.
At this stage it is advisable to clean the lenses. Refer to Section 18
`Cleaning’ for more information. A simple visual check may be
enough to confirm the lenses are clean.
NOTE
