Calibration for weighing instruments
November 1st 2007

New calibration software has been launched that enables process manufacturing companies to manage the calibration of their weighing instruments, improving the efficiency of the calibration process, while also guaranteeing a traceable, auditable set of weighing records.

CMX Calibration Management Software, from calibration specialist Beamex, now includes new calibration management functionality for weighing instruments, including Eccentricity Tests, Repeatability Tests, Weighing Tests and Minimum Capability Weighing Tests, to assist manufacturers in complying with all calibration requirements.

CMX also stores other compulsory information, including traceability of used weight sets and weights; environment temperature before and after calibration; environment pressure and humidity; date and time; and who performed the calibration. All this information can be entered into a PC at the workstation or via a handheld Pocket PC. The software automatically produces traceable and auditable calibration certificates of all performed calibrations.

Alex Maxfield, director at Beamex comments: "Most of our customers, particularly in the chemicals, pharmaceuticals, food processing and beverage sectors, possess a diverse range of weighing instruments, which need to be calibrated regularly. For several years now, these companies have been looking for a system that could manage both the calibration of conventional process quantities – such as pressure, temperature, flow, electrical and pH – and of weighing instruments. After two years developing the software, Beamex has now fulfilled its customers' wishes."

Available as an option with Beamex's CMX Professional software suite and as standard functionality in CMX Enterprise, the new weighing calibration function enables companies to manage the calibration of both conventional process instrumentation and weighing systems, improving the efficiency, accuracy and traceability of the calibration process.

The purpose of calibration is to determine how accurate a weighing instrument is. Although most weighing instruments are accurate these days, regulatory bodies often need to know just how inaccurate a particular instrument or weigh scale is. CMX's weigh scale calibration function enables companies to configure calibration and test each weighing instrument. Copying configurations from one weighing instrument to another is easy. Error limits can be set according to OIML or Handbook-44 and wide variation in userspecific limits is also possible.

CMX's versatile calibration certificate and possibility to define a user-specific certificate, ensure that companies can fulfil requirements set for their calibration certificates.
