How do I Resolve the Warning Message:142 WL Calibration Failed?
If you are performing wavelength calibration using the instrument's built-in light source, the warning message is an indication that the monochromator needs to be repaired.
Please visit our Contact site to locate and contact your local Yokogawa representative to have your unit serviced and repaired. http://tmi.yokogawa.com/us/contact/
If you are performing wavelength calibration using an external light source, please adjust the level of the light source so that the wavelength is within the calibration range.
