Delta Pulse - Take 2

[kt315]

thank you GeoMax.

No component list no instructions just a board, not great.

main thread on this link, just read page-to-page, slowly. the DP matter is living from 2002-2003 when this forum had been just made.

Hi I bought a Delta Pulse Legend + board rev 5 I think. Access to information archive never worked. Can you just send me the information or post it here without having to go round the houses. No component list no instructions just a board, not great.

Hello Infamy,

What you're saying isn't true. I also bought a Delta Pulse Legend Board Rev. 5 from KT315 a while ago. All the documentation was included; you just had to save it. You probably didn't save the files.
The archive was also always downloadable and working. I've never had any problems with it.

[kt315]

load whole archive and delete that you do not need https://drive.google.com/file/d/1P4a...usp=drive_link

[Infamy]

yes, i sort files constantly and put RAR again.

i do not see your coil but you have to use for test very small coil. also your coil must hang halfway up the ceiling of your room.

what i want to say you.... any test in your home will be dirty, very far from reality.

I replaced lf357 with another one in my felezjoo but the same problem. Before a month ago it was work fine.

[kt315]

if the sound returns its cause is fake LF357, low Slew Rate. your issue now to seek the original.

Hello, My device is delta pulse 2 was working fine.... Today, I tried to turn it on and found it only works in manual tune.
In automatic mode, when I press the reset button, the sound disappears for a few seconds and then returns.
Can someone help me?

Thank you, KT315! I'll put it on the coil connector.

[kt315]

better inside a coil. but for tuning you can not open clued coil. in DP the damping resistor sets on the PCB. also, you do not need to tune the resistor as DP is working
with 40us FIRST DELAY.

Hello! Sorry for the stupid question (I haven't made PI for a long time). Where is the correct place for the damping resistor? DELTA PULSE device. Thank you!

Ok , fine , can i have a pic
regards

I see LF356 bought from Lemona (electronics shop) is not so fast I waited. even buying in shop you are not be guaranteed. so the pcb will send AS-IS. I have not possibilities and time to sort through them.
anyway you can change the op amp on yours in anytime.

[kt315]

really I do not know SNIFFER XR7, DBP2010, EURODEC, PIMDEC is one schematic or not. can anybody give clear answer?

[Ali06]

I don't have any knowledge of electronics. Can you help me install it?
