How do I Resolve the Warning Error 142 at Wavelength Calibration on AQ6319?
The warning "142 WL calibration failed" is displayed when a level of light source is not enough at wavelength calibration or calibration cannot be executed because wavelength difference is out of calibration range.
There are three suggestions listed below.
- Please clean the connected fiber cable or exchange the cable for another
- Please initialize the alignment adjustment value and wavelength calibration value
- Please initialize the current parameter setting value, data, alignment adjustment value, and wavelength calibration value
After restarting, please try the wavelength calibration again.
- Press [SYSTEM] and <PARAMETER INITIALIZE> key
- Select ALL CLEAR
- Select EXCECUTE
- Please confirm output level of standard light source (CW, around -22 dBm) by optical power meter
