For sale bare boards for Delta Pulse/Sniffer XR-71

[chuubaba]

My oscilloscope is Two channel 20Mhz

[kt315]

is your oscope two channel or one?

[chuubaba]

decrease a threshold of the indicator shifting to 10v.
set R52 33k.

Now R52 is 33k and the problem is fixed. Thank you.

Lets continue other tests.

After i attach the coil "both LED are ON"

[kt315]

I immediately notice that Low battery indicator is ON despite full 12V power supply to board.

red led is LOW, green led is GOOD. what led you see is light?

now you have to do a coil for test. not for seeking. just for test.
this is small coil 300-500uH.
solder MOSFET. connect a coil. connect push knob RESET.

8. Set pots in pre-set position:

- DEPTH ? min, at left side, counter-clockwise
- DISC ? min, at left, counter-clockwise
- GEB ? middle
- SENS ? middle
- T/HOLD ? middle

turn on and hear the sound. press RESET.

Wire Diameter 0.55mm.
20 turns.
Coil diameter 281mm.
Coil Resistance 2.7 Ohm.
Coil inductance 331 uH.

I have attached the reset button and the speaker.

It is detecting iron. I immediately notice that Low battery indicator is ON despite full 12V power supply to board.

It is not detecting copper.

T4 and T5 time period is 10mS or 10000 uS. The frequency is 100Hzs.

Now to next test please.

[chuubaba]

you have to see whole period. click timing scale on 2ms (MILLI--).

TRASH??? PDF with detailed oscilloscope pics???? WITH ALL TIMIGS????
so do not ask me more the guide. you are not able appreciate right aliens' hard job.

Does this look like your Delta Pulse Rev 5 board?


Are these the components used in Rev 5??


Have you seen the frequency used by him ??? This PDF can be gold for those building this brand and model for these settings but for DP REV5 it is trash. Why you misquote the work of right alien ??? You know very well about my level of skill and knowledge. It clearly says this is turkish board. You disowned turkish board many times and refused to discuss about building and performance problems faced by members. But now you are giving me same design as guide for building DELTA PULSE REV 5 !!!

[kt315]

Don't give me trash.
