2. The system sets the laser to the minimum setting
specified in the Automatic Control dialog box and
acquires a spectrum.
If the signal intensity is:
• Too low with the laser at minimum—The system
continues with step 3.
• Too high with the laser at minimum—The
system begins acquiring in Acquisition mode.
• Within range—The system begins acquiring in
Acquisition mode.
3. The system sets the laser halfway between the minimum
and maximum and acquires spectra.
For the first set of Shots/Spectrum, minimum and
maximum laser settings are taken from the Automatic
Control dialog box. For subsequent Shots/Spectrum,
minimum and maximum laser settings are determined
as described in step 4.
4. If the signal is too low, the current setting is used as the
new minimum setting. If the signal is too high, the current
setting is used as the new maximum setting.
5. The system repeats step 3 and step 4 until either the
signal falls between the specified maximum and minimum
values, or the difference between the maximum and
minimum laser intensity in step 3 is smaller than the laser
step size specified in the Automatic Control dialog box.
