Calibration methods
Depending on the predefined calibration interval, opening the measurement menu will automatically show
a calibration prompt. Calibration can also be started manually.
The device is calibrated using one of the following calibration methods:
•
2-point calibration: Calibration using distilled water and another calibration standard (300 mOsmol/kg
or 850 mOsmol/kg)
OR
•
3-point calibration: Calibration using distilled water and two other calibration standards (300 mOsmol/
kg [SS-276] or 850 mOsmol/kg [SS-277])
The calibration method, the calibration standards used for calibration, and the calibration interval are
defined by the lab supervisor during start-up (
