Selle rakenduse puhul vajatakse üksnes saatjat. Ühendage
kaabliklemmid RJ 11 ühendusega, ühendage kaabliklemmid
mõõdetava objekti külge ja lülitage seade TEST-moodusesse. Kui
samaaegselt vilguvad üks või mitu dioodi 1 kuni 8, siis on testitav
ahel suletud. Kui ükski neist dioodidest ei vilgu, siis on mõõdetav
ahel katkestatud. Vt selle kohta ka vihjet 1.
Ühenduse kontroll
Juhtmetele järgnemine
Ärge teostage mõõtmisi vahetult pingestatud või signaali juhtivatel kaablitel ega
nende läheduses! Valitseb eluohtlike elektrilöökide ja seadme kahjustamise oht.

Ühendage kaabliklemmid saatja RJ 11 ühendusega, ühendage kaabliklemmid soovitud
juhtme külge ja lülitage seade SCAN-moodusesse. Seejärel otsige vastuvõtjaga testi-
mismooduse klahvi (15) allavajutatult hoides juhet, vt pilti a. Seadke signaal vastuvõtjal
maksimaalse mõõtesügavuse saavutamiseks kõrgeimale helitugevusele (14).
Vihje 2: Olenevalt rakendusest võib osutuda mõttekaks signaaliliik ümber seadistada.
Selleks vajutage SCAN-mooduses klahvi (7). Olekunäidiku (6) vilkumine roheliselt näitab
moduleeritud signaali, punaselt vilkumine konstantset signaali.
– Lülitage mõõteahel pingevabaks.
– Kaablis ja ümbruspiirkonnas paiknevad varjestused (metallkatted, metalltarindid
jne) vähendavad vastuvõtja lokaliseerimissügavust.
