5. Assemble the opaque glass plates as shown in Figure 48 below.
Secure the glass plates in place by sliding them under the
thumbscrews and tightening the screws. Note the signal value
printed on the scattering plates because it is needed during the
following steps. Remove the zero plugs from the receiver and
transmitter optics.
NOTE
opaque glass plates are not interchangeable.
6. Remove the plastic protective plate from the seating surface (3 in
Figure 48 below) of the calibrator assembly on the measurement
unit.
7. Install the calibrator assembly on the measurement unit as shown in
Figure 48 below.
8. Move away from the optical path.
9. Give the CALIBRATE CHECK command. The command takes
about 90 seconds to complete.
10. The value produced by the check command must be close to the
value printed on the scattering plates. If the difference is less than
3%, the calibration is correct. In this case, leave the opaque glass
plates in place, write down the signal value, and continue with
section FSM102 Mechanical Alignment Check Procedure on page
175. If the difference is more than 3%, leave the opaque glass
plates in place and continue with the calibration procedure.
