7. Calibration Step
The analyzer should be warmed up for at least 30 minutes before starting the calibration
procedure in this section. Remove the calibration label from the front panel and press the
calibration switch once. When the calibration has been completed, press the calibration
switch on the front panel again (this switch is equipped with a hardware protection circuit to
avoid calibration data loss).
