Advanced Calibration and Data Management
Full Digital Calibration simplifies calibration procedures by eliminating the need to continuously load and unload calibration weights to adjust Zero and Span. The internal calibration mass with motor drive enables convenient, repeatable calibration without external weights. GLP/GMP/GCP/ISO compliance allows for balance management through LIMS systems, with output of date, time, balance ID number, serial number, and calibration data to an AD-8121B printer or computer.
Enhanced Operational Features
The Data Memory Function stores 200 pieces of weigh data for later retrieval and analysis. The Automatic Counting Accuracy Improvement feature ensures optimum count accuracy through continuous recalculation of average piece weight. Windows Communication Tools Software provides easy transmission of weighing data from the balance to a computer using the RS-232C interface. The Auto Power On Function automatically turns the balance on when plugged in, streamlining laboratory workflows.
