and press Enter.
9 Move to <Range Mode>, press Enter, move to one of the following range 
modes:
•<common>, you set the same <Range> for each Power Meter,
•<individual>, you must choose an individual <Range> for each Power Me-
ter, 
•<Auto>, the auto-ranging mode, ensures that the result has a displayed val-
ue between 9% and 100% of full scale, and
• press Enter.
Make sure that you install Power Meters that have similar wavelength 
ranges. The wavelength range of the application is the overlapping 
wavelength range of all installed Power Meters

If you choose <Auto> and the power range changes, the time base of the 
stability application will be disrupted.
