Ohaus recommends that analytical balances like the EP64 be professionally calibrated at least once per year, or more often depending on frequency of use, criticality of measurements, and compliance requirements. It is also recommended to perform regular internal calibration (if equipped) and routine calibration checks with certified test weights.
