Using Unique Numbers in Analysis Files
Adding a Unique Number to file names ensures that analysis files are not accidentally overwritten.
For example, if you perform more than one run on a sample with the same File ID and Sample ID, or
if you accidentally reset the Run Number to one (1) in the Enter Sample Information window before
you have completed the total number of sample runs, it is possible that the Multisizer 4 software
could overwrite run files.
Write-Protecting Saved Analysis Files
To ensure that an analysis file is not overwritten:
1. Open the file in the Multisizer 4 software.
2. Select
RunFile > Save
or
RunFile > Save As
on the Run Menu bar.
3. In the Save As dialog box, enter a new file name or location, if desired.
4. In the middle of the window, select Save as read-only, and click
(
Save
)
.
In the SOM Wizard, click
(
Next
)
to proceed to the next step.
Standard Operating Method: Control Mode
Use Step 2 of the SOM Wizard (page 4-2 ) or the Control Mode tab of the Edit the SOM window
(page 4-23 ) to enter settings that will determine when an analysis run will end. The Multisizer 4 can
end an analysis run based on elapsed time, total count, modal count, or the volume of sample that
has passed through the aperture.
<U#> Unique Number (File Name Generation window only). Including a unique
number is recommended to avoid accidental file overwrites (see
Using
Unique Numbers in Analysis Files , page 4-6 ).
<X> File Extension. You can select the Multisizer 4 default (#M4) or choose a new
extension.
