Three simple steps to simplify balance testing.
Weighing equipment must be inspected and tested at regular intervals to ensure consistently accurate results. Many laboratories, however, test too frequently or perform unnecessary and even incorrect tests. The combination of Metler Toledo’s GWP Verification, GWP Excellence and weight sets is an easy-to-implement solution that simplifies correct routine testing strategies.
Based on market demands for increased guidance, Mettler Toledo has developed Good Weighing Practice. This global, risk-based weighing guideline allows companies to reduce testing costs while keeping safety a priority. There are three steps to simplifying the routine testing:
* GWP Verification: the improvement potential of even the most rigid quality system (in terms of quality assurance, cost reduction and the increase of employee productivity) has been validated by multinational companies. GWP Verification provides a colour-coded executive summary, which illustrates the status of each balance in regard to the potential risks of inaccurate measurements. Specific recommendations for each balance or scale are then derived from this report. This includes information on how to maintain accurate results with minimal testing efforts, such as routine tests types, frequencies of checks and calibrations, required test weights and the control limit for each test.
* CarePac Weight Sets: the GWP Verification assessment provides details on which weights should be used for each test. GWP states that routine testing with just two test weights is sufficient. CarePacs contain two carefully selected certified weights to test close to the minimum and the maximum capacity of the balance. Handling only two weights simplifies routine testing and saves on considerable purchase and re-calibration costs.
* GWP Excellence: The third step is to put the optimal testing regimen into practice. Using the information from the GWP Verification report, all testing procedures can be implemented directly in the balance firmware, which is a built-in safety feature in all new XP, XS, and XA balances. This includes which tests to carry out, how often and using the correct CarePac weight set. Whenever a test is due, the balance user is prompted to perform the relevant test and is given step-by-step instructions directly on the balance display.
Finally, the combination of GWP Verification, GWP Excellence and CarePac weight sets is an easy solution to simplify a routine testing strategy. This allows users to save by eliminating unnecessary testing. Thorough documentation of the balance performance and routine tests, the balance firmware helps to avoid out-of-spec results, negative audit findings or even warnings.
