Malvern Instruments Mastersizer X - Editing and Deleting a SOP

Max Obscuration
The maximum obscuration defines the upper limit for the obscuration value
during the inspect stage. If the maximum value is exceeded, the user has the
option of either accepting the obscuration or rejecting it, in which case there is a
prompt to clean out the sample tank and start the measurement sequence again.
The default maximum obscuration is 5% larger than the minimum obscuration
value. Good practice dictates that a value less than 25% should be entered but the
software will allow values up to 99%.
Date & Time
The date and time that the standard operating procedure was generated or edited
is automatically stamped on the SOP by the macro.
Editing and deleting a SOP
What happens if you make a mistake when defining your SOP? Malvern provides
a separate macro that allows you to edit or delete an existing SOP.
To run this macro select Control-Edit Qspec MS1 SOP. A dialogue will appear
asking you to select the SOP you wish to change. Type in the number
corresponding to the SOP you wish to alter and then press “OK”.
A second dialogue will then appear asking if you wish to edit or delete the SOP.
Enter the appropriate option. If you selected “Delete” the SOP will be removed
from the list of available SOP’s .
If you select “Edit” the macro will run you through the options for that SOP.
Make any changes you require.
All SOP’s are stored in one file called “SOP.INF”. Up to 19 SOP’s may be stored
in the file.
