PR balances are classified into two categories, InCal models and ExCal models. InCalmodels have a built-in calibration mechanism which can calibrate the balance automatically and does not requirethe use of external calibration masses. If preferred, InCal models can also be manually calibrated with externalmasses. ExCal models are calibrated with external masses. Make sure to have the appropriate calibration massesavailable before beginning calibration.RS232
