Measuring Optical Power

With the dust cap on the power meter, press

the power button. The meter will display ‘null’,

indicating that it is ready to measure and

is currently receiving no power. Press the

wavelength ‘λ’ button to change to the desired

wavelength. Select 850nm if using the IDEAL

33-926 light source.

Remove the dust cap and connect the meter

to a cable to begin taking measurements. The

default measurement mode is dBm and can

be changed to mW by holding the ‘λ’ button for

2 seconds then releasing.

In addition to using a separate light source, the

power meter can measure the output from any

optical switch, media converter or other device

as long as its wavelength is within one of the

operating windows of the 33-927 power meter.
