Tinklo, telefono, multimedijos kabeliŇ ir atskirŇ laidŇ aptikimas.
Suderintuvo laidŅ ir (arba) ieškomŅ kabelř sujunkite su siŸstuvu ir prietaisŅ perjunkite ř
SCAN režimŅ. Jeigu reikia, siŸstuvŅ prijunkite prie tinklo arba telefono lizdo, žr. pav. b.
Matuodami kabeliŸ gnybtus prijunkite taip: raudonŅ gnybtŅ prie ieškomo laido, juodŅ
– prie masŏs (řžeminimo laido arba ekrano). Po to imtuvu ieškokite prijungto laido. Šiuo
klausimu taip pat žr. 2 patarimŅ.
3 patarimas: norŏdami geriau lokalizuoti ieškomŅ kabelř, garso reguliatoriumi (14) pamažu
mažinkite imtuvo signalŅ. Ieškomas kabelis aptinkamas dŏl garso skirtumŸ; jř rodo
šviesiausiai švieňiantis bŴklŏs indikatorius (12) ir (arba) didžiausias signalo garsas.
4 patarimas: geriausias rezultatas gaunamas, jei matavimo antgalis (10) tiesiogiai kontak-
tuoja su metaline ieškomo laido dalimi. Susilietus girdimas itin ryškus signalo garso šuolis.
Stipresni signalai gaunami kabeliŸ galuose (pav. c) arba tiesiogiai ties atskirais laidais
(pav. d).
5 patarimas: galimos triktys (burzgimas ir pan.) gali bŴti sumažintos řžeminus atgalinius ir
ekranuotus laidus matavimo rezultatŸ perdavimo laiduose. Gali pakakti ir řžeminimo ranka
arba pirštais.
6 patarimas: lygiagretŴs elektros laidai gali sukelti trikdantř burzgimŅ matavimo rezultatŸ
perdavimo laiduose. Jei trikdymas per stiprus, jeigu řmanoma, matavimo metu atjunkite
elektros tiekimŅ.
7 patarimas: televizoriŸ lizduose (dažniausiai) gali bŴti řrengti Ö ltrai, kurie neigiamai veikia
matavim
Ņ. Tokiu atveju išmontuokite TV lizdŅ ir matuokite laidŅ tiesiogiai.
