Verify Proper Operation of the Equipment, cont.
Once proper operation has been verified, remove the second patch cable from both units and set it aside.
Connect the power meter and light source together with the mandrel-wrapped patch cable as shown in Figure 4 below.
Compare the reading on the ZOOM 2 to Table 1 for acceptable power levels. The patch cable should be replaced if it is
below the acceptable power level.
Once proper operation has been verified, continue on to the next step.
Set Reference
Setting a reference is commonly referred to as “zeroing”.
With the power meter and light source still connected as shown in Figure 4, press and hold
button on the ZOOM 2 to
set the reference for 850nm.
The ZOOM 2 display should change to show readings in ‘dB’, and the power reading should be approximately 0.00 dB. This
means that the meter and light source have been successfully “zeroed” at 850nm.
If testing at 1300nm is also required, connect a mandrel-wrapped patch cable to the 1300nm port, then
perform
