8 .7 .3 Running the SQmin Minimum Initial
Weight Application
The SQmin application compares the current weight
value with a defined minimum initial weight . The defined
minimum initial weight is defined in a quality assurance
system, for example . This ensures that the weight values
are above the defined minimum initial weights and thus
meet the requirements of the United States
Pharmacopeia (USP)
SQmin is not the same as the minimum load
"Min" in legal metrology .
Requirements
− The SQmin application must only be set up and
activated by Sartorius Service.
− The "SQmin" application is activated .
Procedure
Place a sample on the weighing pan .
t
If a red SQmin value is displayed: The weight value is
y
less than the defined minimum initial weight . The
weight value is displayed in gray . The weight value
cannot be saved and cannot be printed out in
applications (depending on the setting in the "Safety
level" menu) .
