DP not reflex!

Dear Geo
my DP was finished yesterday(I used Kt315 PCB and elements)TR1 is IRF840,but i have some problem
and question.pls guide me what must i do?(below result was without connect coil to DP)
1- i know PR1 pot is for tune the frequence but in which check points exacltly i can see correct frequence
(100Hz) by Osiloscope or Fr meter?
2- When i power switch ON,the power LED turn on for a very shot time and turn off again and it will not be On but Tune switch
work and microAmp move up,what is the problem?
3- i had a mistake!!!the battery was short contact and circuit was connect,is it possible circuit damage ?
is it possible send me ur DP schematic,PCB and element detail ?
sorry for bad english
thank u very much and goodluck my friend

Hi, To read the frequency you must connect the probe at the tr2.
I don't think that the circuit has damaged from battery short.
If you will read this thread from page 1 you will find every DP schematic. I use the schematic that writes Micron Electronics........Delta Pulse.

Hello All

I attached single sided delta pulse in sprint layout 5 format drawed By Hakan Durmaz from elbombacı design pcb .he has www.durmazonline.com about detectors Please write if find any errors

Hi Oscar. Connect a coil and look if the detector response at any metal. If yes change the led or the series with led resistor.

DP Help

Dear Geo
My DP coil has alminium foil sheild(i use Cat.5 network cable for it).
1-where must be coil sheild connect on DP ?
2-where must be Coaxial cable shield connect?
thanks and goodluck my friend

Hi.
Coil shield must be connect to +E (+12V). I have tried it at -E with the same results.

one side pcb for DeltaPulse

Hi
dear geo
is it really Correct one side pcb for DeltaPulse?
how many power? does has it value for build?
thanks for reply.
good luck.

Hi. I did not construct it. But as i saw at a Turkey forum this pcb works well.
Download the demo version of sprint layout 5 and open the file son.lay who Erolunall has post here.

Dear 786

I constructed it and working good.I will put picture of DP here soon.

Elbombacı made LCD for DP.

You can find below link about single sided dp but YOu have to ask elbombacı about LCDç

Hi Nelson

There is no performances changing.But very easy for building.
I attached parts replecement.
I wonder can we attach Digital ampermeter to delta pule below link?

Thanks for this information.
Yes, when i get it working, i ll try to place a meter too.

Original Delta Pulse has an analog instrument (microameter). But for me ....DP don't need it. The sound is analog to meter indication so why to use it ?????
