What should the λ-Check option be set to on the DR1900?
DR1900 λ check function
The λ-Check function defines the frequency of the lambda calibration on the DR1900. The default for this option is Auto. When Auto is selected, the system identifies if a motor relocation to a specific position at startup is needed. When Always is selected the motor is relocated to a specific position every time when the instrument is set to on. When Next power on is selected, the motor is relocated to a specific position the next time the instrument is set to on and then, the instrument changes back to auto mode.
