Calibration Failed

The intensity maximum was not found during wavelength calibration.
Calibration 0 Failed: Zero-order calibration failed.
Calibration 1 Failed: 656 nm calibration failed.
During zero-order and 656 nm calibration, the detector searches for the intensity
maximum. If the maximum is not detected within the scan range, the error message is
generated.
Probable Causes
• Lamp is off.
• Incorrect flow cell installation.
• Flow cell contamination or air bubbles.
• Intensity too low.
• Current step value too far from maximum.
• Misalignment of the grating assembly.
• Defective grating assembly.
• Defective VWM board.
