Key parameters determined in a weight scale and balance calibration are repeatability of reading, pan position error, scale linearity and accuracy. Weight scale and balances are calibrated to establish accuracy and to confirm they are performing to manufacturer specifications.

MQC uses standard weights with an object density of 8000 kg/m3 (suitable weights are described in OIML R111-1[3]) in each of nine different accuracy classes and in air density of 1.2 kg/m3. A thermometer with a calibrated accuracy of 0.2áµ’C is used to measure ambient temperature during the balance calibration as temperature may affect the sensitivity of the balance. Standard calibration is taken at four loads across the weighing range, excluding zero. Customers may always request weighing ranges and loads in an effort to best meet their precision measurement specifications.

All weight scale and balance calibrations are performed in our environmentally controlled laboratories (both temperature and humidity are closely monitored 68°F with relative humidity not to exceed 40%) to give the lowest degree of measurement uncertainty. Preparation of your precision measurement test equipment is just as important as the calibration. For weight scales and balances the test instrumentation is thoroughly cleaned and inspected and allowed typically 24 to 72 hours to stabilize the temperature (thermal equilibrium) of the instrument. Common items checked for during preparation for calibration of your item include location, condition, cleanliness, drafts, temperature, poor table balance, level, etc. Preparation varies and is equipment specific.
