Whenever the instrument is calibrated, 2020 updates the selected
Cal Memory only. Each Cal Memory must be calibrated at least
once a day. Frequency of calibration will depend on ambient
conditions and instrument response. If ambient conditions change or
the response has drifted, a calibration must be performed for each
Cal Memory to ensure reliable operation.
