Delta Pulse

[Nikolov]

Yes C4,C5, there are in Sense circuit, but I can't find with 63V in the shop have with 630V currently I put ceramic capacitors and this is not good solution!

Hi Nikolov
Do u mean C4,C5=1.5nf /63v~100v and u do not get u can use 630v but big!!!

Thanks but the things that you're saying , it looks like we have 2 voltage source
one to give +12v
one to give -12v
because the voltage of negative prob of a battery is not -12v , it's like ground
Am i right?????????
There's no circuit for making -12v in the schematic

-12 goes to your battery minus clemma. +12 goes to your battery +12 clemma. WHAT IS NON-CLEAR THERE FOR YOU??

Hi Kazem2114
ALL explained IN PIC. IN CASE DP.(NOT IN U TEST)

Hello
Can I put capacitor 1.5nF (MC7.5 1K5) block but it's with 630V ?

Hi Kazem2114
I hope I explained Thought.

Hi Kazem2114
could you please put a photo!

Thanks for answering
This is my simulation...It gives me just -1.2mili volt

Hi dear
I had made delta pulse and it doesn't work at all... I need some help


-E=-10.6V.

hi
could you please help me more??
I can't get " -E=-10.6v " there is a positive voltage here...I checked my connection, they're not wrong
I simulated this part and it doesn't give me any negative voltage??????????????????????
what's the problem????????

Hi pigeon
OK....test the project of lcd discrimiation Alone,To determine if the defect alone or the connection with Delta.

ok.thank you

stage on T2 and T3 is serving for against overloading of preamp. it moves impulses of sampling at right side of 'delta' pulse, at a zone with more lower amplitude, beginning from some level or threshold on output of the preamp. so the stage is turn off in some 'diapasone' and does not operate.

what's the role of these 2 parts?????and what's the voltage of " -E/Tr9 "????
I didn't see Tr1 in any parts of circuit but here???[/QUOTE]
Hi Kazem2114
the role of these 2 parts 1- to get +E=+12V,-E=-10.6V.
2-ITS protection T2,T3.
3-Tr1 mean test point.
4-T1 is fet
5-Tr9 test point=-10.6V

Hi pigeon
put a photo ,and the # of LCD use,may the error from conection!!! in this case
not power on!!!!!

hi jap

is the project of lcd discrimiation correct?because i have a pic with the whole program

thank you
