If checking the power meter test cable, the meter will display a diagram about how to connect the additional test cable.

Remove the light source reference cable from the OPM port (but do not disturb the connection to the light source).

Connect the mating sleeve to the end of the light source reference cable, then connect the power meter test cable between the mating sleeve and the OPM port as shown on the meter.

Press any key on the meter to proceed.
