Superscan PI

[kt315]

specs

The settings for the Superscan are as follows -

TX pulse width 500uS

TX pulse frequency 86 pulses per second.

Sample pulse delay 60 - 150uS, adjusted by reject control.

Delay for second sample pulse 1100uS

Sample pulse widths 45uS.

The coil inductance should be 500uH for TX and RX, with a TX resistance of 1.5 ohms, including the cable.

Because of the low pulse rate and wide spacing between 1st and 2nd sample pulses, the unit can be affected by low frequency rf signals and power line noise. The MK2 version has a TX frequency control that can often counteract this. Also the integrator TC is adjustable (response speed) - slower smooths out the noise more.

For best signal on any object, the TX pulse width should be about the same as the decay time of the object signal. A large copper pan could have a decay time considerably longer than 500uS and not give as good a range as a similar size object of less conductive metal.

Ground signals from iron mineralised ground will be strong with a single TX/RX coil, but the Superscan was also designed to use separate TX and RX coils. An outer TX with and inner RX of half the diameter will give much less ground response. Also you can lay a big 10m x 10m TX coil on the ground, and search within it with a 0.5 or 1m RX.

hello KT315. Is there a drawing available for this superscan?

[kt315]

hi TN
you know that people constantly asking me in PM to give files. also the fact that PM is blocked to transfer files.
so i put the files in forum. people also do not answer me with THANKS, like i'm automatic responder robot and they do not blind do that.

so ignore this thread.

I did not want to disturb you. I did super scan. but I want to make this pcb.


thanks for the answer

[kt315]

you have to know i do not keep the secrets from people. all i have i take from this forum. but WHAT TO DO if the people are not able to learn
simplest way to use a search engine of the forum? The Degradation Of Mind. Full inability to do something for yourself.
if i do not have a LAY file it is sure there is not. BTW i do not keep those sprint layout files done by people because they are just trash.

hello Eric.Superscan how to use the most efficient.
I couldn't find a manual.
Thank you.

Hi! Can anyone send me the superscan pcb in pdf lay or even better assembled!

[loukilouk]

Nothing?
Nothing?

[kt315]

Eric Foster's HD was crashed, all files were lost in moment. absolutely all. he did not archive the files. no PCB, no schematics,
no diagrams. just ITMD is stayed like a monument of basalt. strong and hardest. on centuries.

Ok my friend, thank you!!!

Hello, I made it, I can't debug it, can you help me?

Hello, I made it, I can't debug it, can you help me?

Do you have an oscilloscope? Do you understand electronics?

[ZOUjiarui]

Do you have an oscilloscope? Do you understand electronics?

I am an electronics enthusiast and a novice metal detector maker. I have a small oscilloscope. Do you want to set the frequency of a coil to 500hz? Thank you

I would like to ask the master, whether it needs outdoor debugging? It makes a sound, but these are the only two positions that can change the sound. Thank you
