t5:
Once it is ready to measure, it is set to "Ready". "Laser On" indicates that the laser should now be
switched on. The laser pulse shouldn't have been triggered in advance, since in that case it could
be gone by the time the device is ready to measure!
t6:
The laser pulse triggers the actual measurement.
t7:
Once this has come to an end, "Measurement Running" and "Ready" are deactivated.
t8:
From this point on, the laster pulse "Laser On" can be switched off, since it will not be needed for
subsequent calculations.
t9:
Once calculations have been completed (or a fatal failure has occurred), the flags are set to "Finished"
and "Idle".
If the "Measurement Failure" flag is activated, a fatal error has occurred and the measurement or
calculation has been disrupted. The cause of the failure is coded in the "Error Identified" log.
If "Measurement Failure" is not set, the measurement and calculation has been successfully performed
and the results can be found in the "Beam Parameter" results log. The maximum value of the raw data
and an indication of how many pixels were overloaded is coded in the high byte of the status value.
It is possible that the "Irradiation Failure" flag has been set; in that case, a non-fatal failure has occurred
(measurement overloaded or underloaded, beam on the edge of the measurement window). The cause
is coded in the "Warning Identifier" log. Beam parameters have been determined, however, and these
are available in the results registers.
t10:
Results as well as failure flags and identifiers are maintained until the next measurement is initiated
by "Start".
