HL Leakage (optional)
The HL Leakage (Home Leakage) test provides the ability to quickly find and fix hard to
locate ingress sources in the home, breaks in coax, loose connections, etc.
It allows a tech to localize leakage at subscriber premises using the ONX paired with the
Seeker HL Leakage Transmitter. This is an optional feature and requires the HL transmitter
kit.
You can also run HL Leakage tests in OneCheck, if enabled.
To run HL Leakage
1. Select HL Leakage under the CATV menu header. The HL Leakage screen appears.
2. Attach the HL Transmitter to premises coax and turn it on to high output
(+60dBmV/120dBμV).
3. Attach HL Leakage rubber duck dual-band antenna to ONX RF port 1.
4. Start the test by selecting the
Start button at the bottom of the screen.
5. Walk around noting where leak level, tag, and audible tone indicate a higher than
desired leak.
6. When HL Leakage is complete press Stop .
