[mohandes]

ok my friend mohandes and then I will deal around October will then say goodbye for now.
appointment in October Well..

hi my friend
sorry me for late.
i buy dig osope and check again all out put and ok like oscillogram except pin6 ne5534.
i use dif parallel res but dont change,(not better)
can you help me please?

[mohandes]

Hi, dear hello, have a question want to consult everybody, STAR - G RV8, RV9, RV10 these three should be how to adjust, after I adjust the output is zero, then adjust the DELAY when the output is completely changed, is not zero, DELAY (50-150 (us) should be given the maximum or minimum and then to adjust RV8 \ RV8 \ RV9 \ RV10??????? And two identification indicator light should be in normal full bright or is completely destroyed, or is any light only??????? RV12 should be how to adjust, thank you, the hope can get the answer here, thank you

all your question answerd befor.
i have your problem too but now i can not find parralel resistor to coil.can you help me?if i complete ,then we can search about my problems.
can you send here your design pcb?
when i complete that all point can be set.for example i can set all oscillogram except pin6 ne5534.
if you study last pages carefull you can find all answer.
regards

i make it too but not sens and not disrim and voice very bad.
2 day latter i will have oscope then i measure all out put and send here .
do you have pcb design ?can you sen here?pls
thanks
my pcb design are ok but not professional .
i make 4 board and test supply and oscillator are ok. now i should find damping res.
regards

STAR-R调整问题求助

I have ready to STAR - G, can be detected, and the sensitivity, still can be but the voice is not normal, not like the voice of the normal pulse, high and low, identification will not adjust, and identify the two lights don't know what should be normal, all of the metal is not detected out or only light a, ask everybody to help, to identify how to adjust, the whole circuit should be how to adjust???????

[QUOTE=g.s;173460]for buddy MOHANDES ...
There are problems in the schematic with POWER SUPPLY As I recall..and a transistor in the transmitter system..
I'll check the files and I'll tell you about THE DETAILS .. I believe understand a matter of time for me..
I think someone here at Forum supposed that I have corrected the initial But finally we have incredibly puzzled.(Perhaps it is intentional self)..better to work on the original SCHEMATIC..
I'll see you from here ..gs..

HI my friend
look this page:http://www.geotech1.com/forums/showt...chematic/page9 and see oscillogram
first i should change the resistor that parallel to the coil (180ohm ,150ohm,120ohm)then i measure by oscope and tell you my result.
but now i have an exam and i measure the next month.

thanks
