7.2 SQmin Minimum Weighing (Secura
®
only)
Purpose: This function is used to compare the weight value with the defined minimum sample
quantity (SQmin = sample quantity minimum) . This ensures that weighing results are
above the specified minimum weight defined by your quality assurance system . This
function is used to observe the minimum weight in order to meet the criteria of the
United States Pharmacopeia (USP), for example .
SQmin is not the same as the minimum capacity Min in legal metrology .
Prerequisites: The balance must be set up by a service technician to be able to use the SQmin
function . The technician will determine the permitted minimum sample quantity and
load this to your balance using the guidelines of your QA system . He will document
this setting via a “Weighing module test as per USP” certificate in which the
measurements and min . sample quantity are logged . The SQmin function ensures that
the weighing results correspond to USP guidelines .
