Need more information , service manual about Multimeter Leader LDM-853A. Can you help me? Thank you very much .
Leader 1021 típusú szkóp. Bekeapcsolás után nem indult, kicsit "szagos" volt.
Kedves kollégák! Ha valakinek szüksége volna erre az eredetileg 20MHz-es szkópra, egy forintért elvihető. Üdv. hegejani
(Megoldva)LEADER 1021 oszcilloszkóp nagyfeszültségű trafó áttekercselése
A címben említett készülék nagyfeszültségű trafójának mindkét szekunder tekercse megszakadt. (Oxidáció, stb.)
Mivel be volt öntve lakkal, nem sikerült letekerni a huzalt.
A huzal vastagságából meg lehet ítélni a menetszámot, viszont a két tekercs egymáshoz viszonyított menetszám arányát nem sikerült megállapítanom.

A mellékelt kapcsirajz alapján mi erről a véleményetek?

Hála a fórumtagoknak, de főleg Istvánfiának, megoldódott.

Működik.

A saját trafójával a következő menetszámok adódtak:

1*-2    10T
3*-4      6T
5-6    10T
7-8  130T
8-9  800T

*- tekercs kezdete.
A félvasak közé 0.05mm papír.
