Fig. 30. Pass Control Dialog.
If the MCS is not collecting data, the Stop command is ignored. If the MCS is collecting data,
the Stop command will stop acquisition after the current pass is completed. The Stop button on
the Sidebar flashes while this final sweep is completed. If you then issue Stop a second time, the
current pass will terminate before completion.
6.2.3. Clear
Clear erases the spectral data and pass count. This command will not operate on an active MCS.
You can also execute the Clear command with <Alt + 3> or by clicking the Clear button on the
Sidebar.
6.2.4. MCS > Buffer
This command transfers data and all pertinent information (pass count, pass length, dwell time,
etc.), from the selected MCS to the buffer. The MCS > Buffer function can also be performed
by pressing <Alt + 5>.
6.2.5. Pass Control...
This command opens the dialog shown in
Fig. 30 appears. This function is available
in both buffer and MCS modes, even if the
MCS is acquiring data. However, for the
buffer and for MCSs acquiring data, the
current settings can’t be changed.
Enter the number of channels to use for
MCS acquisition in the Pass Length field.
The minimum pass length is 4 and the
maximum is 65536.
The Pass Count Preset entry field is used
to enter the number of passes to collect.
With this preset condition, the MCS stops
counting when the pass count reaches this
value. To turnoff this preset, enter 0 (zero) or the word “off”; the MCS will then collect data
until the Stop command is issued.
In the Dwell section, select either Internal or External. For internal dwell, enter the dwell time
in the Bin Width field, then open the adjacent drop-down list and select the time units. If you
select external dwell, the Channel Advance input on the MCS is used to provide the signal that
causes the MCS to move from one channel to the next. Set the dwell threshold voltage to a value
