Abstract

Inventia se refera la un aparat pentru încercarea cepselor electrice simultan la curentul de aprindere si la impulsul de aprindere, care consta dintr-un circuit stabilizator, folosit ca generator de curent constant, si un circuit monostabil, de temporizare, urmat printr-o dioda Zenner de tranzistoare, în colectorul ultimului fiind plasat un ampermetru, în paralel cu bornele de masura la care se conecteaza capsade masura, iar în emitator un milisecundometru, în paralele cu un rezistor ce face parte din circuitul de reactie al generatorului de curent constant si determina tensiunea de iesire a temporizatorului. Monostabilul este declansat printr-un comutator, durata impulsului reglîndu-se cu un potentiometru, iar impulsurile scurte obtinîndu-se prin actionarea altui comutator si descarcarea unui condensator.The invention relates to an apparatus for testing the electric plugs simultaneously with the ignition current and the ignition impulse consisting of a stabilizer circuit used as a constant current generator and a monostable timing circuit followed by a Zenner diode In the collector of the latter one is placed an ammeter in parallel with the measuring terminals to which the staples measure and in the transmitter one millisecond in parallel with a resistor that is part of the constant current generator reactance circuit and determines the voltage timer output. The monostable is triggered by a switch, the duration of the pulse being adjusted by a potentiometer, and the short pulses obtained by actuating another switch and discharging a capacitor.
