Minimum Sample Quantity SQmin

Minimum Sample Quantity SQmin

Purpose: This application is used to compare the measured weight value directly with the defined minimum sample quantity (SQmin = sample quantity minimum). This ensures that weighing results are within tolerances defined by your quality assurance system. This fulfils the requirements of United States Pharmacopeia (USP). According to USP guidelines, the measurement uncertainly can be a max. of 0.1% related to the initial weight when weighing substances for quantitative analyses.

Requirements: 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.

Combination options: Mass unit conversion, second tare memory, individual identifiers, (DKD measurement uncertainty)

Individual Identifiers

Purpose: You can define identifiers for the following print jobs:

–Printout by pressing PRINT

–Task start

–Task end

–Initialization (for calculating applications only)

–Result (for calculating applications only)

–Component (for logging applications only)

–Evaluation (for logging applications only)

These identifiers are also printed in the log.

Combination options: Second tare, (SQmin function, DKD measurement uncertainty)

Example: You want to configure the application as follows:

–You want the printout to be activated with the PRINT key.

–You want to configure the application so that four identifiers are included in the printed log, i.e., your company address in three lines and the batch number in one line.

–The batch number is to be counted up automatically.
