Initial Calibration
When the PR balance is first installed, or when it is moved to another location, it must be calibrated to ensure
accurate weighing results. PR balances are classified into two categories, InCal models and ExCal models. InCal
models have a built-in calibration mechanism which can calibrate the balance automatically and does not require
the use of external calibration masses. If preferred, InCal models can also be manually calibrated with external
masses. ExCal models are calibrated with external masses. Make sure to have the appropriate calibration masses
available before beginning calibration.
