SQmin Function
Purpose To display the allowable minimum sample quantity “SQmin" (sample quantity
minimum) in accordance with the United States Pharmacopoeia (USP). According
to USP guidelines, the uncertainty of measurement may not exceed 0.1% of the
sample quantity when substances are weighed with the highest degree of accuracy
for volume determination. This additional function ensures that weighing results lie
within defined tolerance limits corresponding to the requirements of your quality
assurance system.
Prerequisites The scale 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 scale using the guidelines of your QA system. He or she 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. These SQmin
settings cannot be changed by the user.
Features – Displaying the minimum sample quality: After you press the k key, the value
is displayed in the text line for 4 seconds.

displayed and weight values are marked with a “!" in the printout.
– GLP header: The minimum sample quantity entered for SQmin can be included
on the printout.
