General Preferences
Click General from the Options window to choose the following settings:
 Show settings when running manual measurements – this automatically
displays the measurement settings window whenever a manual measurement is
initiated. This can be useful during method development where the user needs
to switch back into the record view after making each measurement and then
make slight alterations to the measurement settings for the subsequent meas
-
urement. If this option is de-selected, the settings are still available to the user
by clicking
on the Manual Measurement window.
 Force saving of records – with this option selected every measurement file
will be saved on creation with temporary measurement files no longer being
made. The measurement files will automatically be saved when the software is
closed, so there will be no prompting for the user to make changes.
Note that this option is automatically enabled and cannot be changed when the
21 CFR feature is installed.
 Enable Mastersizer 2000 / 2000E Analysis Emulator – Enable this option
to add 3 additional emulated Mastersizer 2000 / 2000E analysis models to the
list of analysis models in the Data processing - Analysis SOP and record edi
-
tor.
The emulator converts Mastersizer 3000 results to how it would be analysed on
a Mastersizer 2000 instruments, and similarly for a Mastersizer 3000E result
the Mastersizer 2000E instruments is emulated.
Refer to Data processing - Analysis SOP description in the Making meas-
urements chapter.
 Enable virtual lens ranges – This enables the controls on the advanced anal-
ysis page of the SOP for virtual lens ranges. Virtual lens ranges limit the result
analysis range to that of a legacy instrument, such as a 300mm lens used on a
Mastersizer X.
Refer to Data processing - Analysis SOP description in the Making meas-
urements chapter.
 Display results to same precision as Mastersizer 2000 – this option ena-
bles the software to display results to the same precision as used in the Master-
sizer 2000 software. Results will be displayed to 3 decimal places.
