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
130. If the difference is more than 3%, leave the opaque glass
plates in place and continue with the calibration procedure.
