Front Panel Operation – OP815
IL Mode: Pressing the Ref button in IL mode executes a reference cycle. For single
wavelength devices, or dual wavelength instruments with individual ports this involves
taking the reference at the selected wavelength. For dual wavelength instruments this
involves taking the reference for the first wavelength, then repeats the same for the
second wavelength. The referencing cycle can take up to 5 seconds.

The OP850 has a mode button [mode] in place of this button. When pressed this button
operates the same as the buttons described below.
