FIELD CALIBRATION - PATCHCORD TESTING
This Field Calibration is a 4-step process. Steps 1 and 2 are performed with the hybrid
(RJ45 Plug to RJ45-TIA-Reference-Jack) patchcords connected to the Handsets using
the kit’s mini patchcord. Steps 3 and 4 are performed with open-ended hybrid
patchcords (Only one end connected to the Handsets).
To calibrate the tester, perform the following:
Step 1
¾
Connect the Category 5e/6 – RJ45 adapters to the Display Handset (DH) and
Remote Handset (RH). Power both units on.
¾
Connect the RJ45 plug of the first hybrid patchcord to the Remote Handset (RH).
Using the RJ45 mini patchcord attach the DH RJ45-TIA Reference Jack end of the
hybrid patchcord to one end of the mini patchcord and then connect the other
end of the mini patchcord to the Display Handset (DH).
Note: Patchcords can vary in length. The most common length used is the 2-meter
length patchcords.
¾
From the DH Ready Screen, select Field Calibration. The Calibration screen
appears.
¾
From the RH, press AUTOTEST to perform the first step of the calibration
process. At the completion of step 1, disconnect the mini patchcord and hybrid
patchcord from the RH and DH.
Step 2
¾
Connect the RJ45 plug of the second hybrid patchcord to the Display Handset
(DH). Using the RJ45 mini patchcord attach the DH RJ45-TIA Reference Jack
end of the hybrid patchcord to one end of the mini patchcord and then connect
the other end of the mini patchcord to the Remote Handset (RH).
¾
From the DH Field Calibration screen, select START or press AUTOTEST from
the RH to perform the second step of the calibration process.
¾
At the completion of step 2, disconnect the mini patchcord.
