How can I set a custom wavelength on my Viavi Powerchek power meter?
Connect the Powerchek to your PC and launch the Fiberchek Pro software. Click on Setup and select Powerchek. Go to the General tab. If there are less than 10 wavelengths defined then select ADD to define the new wavelength. If there are already 10 definitions then you will need to edit or delete one of the existing entries, as 10 is the maximum number that can be stored on the device.
