help for delta P.

[okantex]

dp must work better at higer frequencies.
why?
lorenz works between 1400h-2100h at different coils accoording to adverts.
and I have a question.
on dp there are two leds.
what do they show?
when they start emitting lignt.
in my dp they both start emitting lignt at the begining.
must not led parallel to 4700s start at tes begining.
ı thougt it must start after battery gets weak.not at teh begining.
btw I just charged my battery.

according to bandido pulse manual.it must start later.

offers please

Lorenz is Lorenz and DP is DP. I wrote that i dont know...... maybe DP to be able to work good at Biger frequency.....Try it.
At DP the two leds are for power ON and for Low bat. If the low bat led is lighting then the bat is lower than 8v if i remember good.
Bye

Hi Geo
battary is 12v 2.3A
it was first time I charge it.I charge it with my adjsutable voltage battery. at 12v option.it is output is 500mA according to written on it.
I charged it 4 hours and 15 minutes.
2.3A /500mA= 4hour 20minutes for recaharge.
but I will measure battray.

is there anybody whose leds operate like Geo 's discription.

[okantex]

btw GEo
I did not use zener diot.all are 4148.
last year someone here told me to do this if I can not find zeners.
can this b e problem
.a friend said like this.
and will it casuse any harm to machine

[diminute]

Clear !!!

You must use zeners. 4148 is 0.6V, but in inverse is a great voltage, you battery needs about 1000V for you LOW BATT LED off.

You must used 9.1 Volt ZENER plus 0.6V EB for transistor... if your batt is under 9.6 - 9.8 the led on

diminute

[okantex]

I measured my battery.it is 14v now.

if I do not use zeners ,will it couse problem for pcb or battery.

[Unregistered]

I changed diots.and add zeners .
but still led paralel to 4700 uf is emitting light at the begining.
but the one over pcb stopped emitting light.

this stuation is the opposite of what I was expecting.
is there any problem.

which one must start emitting light when battery gets weak.one n pcb or one parallel to 4700?

Hi Okantex.
The led parallel with capacitor 4700uF is the power on and must be always lights (it is ok now). The other led parallel with transistor T10 must light when voltage is lower than 8...9v. Connect your detector with the variable power suply and vary the voltage .....the led must light when the voltage is low.

[okantex]

Hi Geo
MY variable power supply burned during four hour charge of my new 12v battay.
why ?I dont know.
your opinion looks imposible to me.
as I know output of power suplies are constant 500mA .
our detector as I remmeber works with 130ma in normal and 230 with load.
can not 500ma harm iit.
thanks for your help.

[Geo]

Hi Okantex.
You can connect in series with battery 6...7 diodes (1N4001.....4007) to check the low voltage led

can I use CAT5 ADSL cable.it is screened during production.
can it be used for delta
okantex

[okantex]

unscreened it.
made rectangular coil 60*100 cm.16 turns. ( 0.45mm wire)
results
can detect red briket pieces.
big savage cover (70-80cm diameter.) from 180cm in air.
can not detect aliminium jug at 140 in ground.jug is upside down and diameter is 40cm.

for small coil , D20 T30 0.45mm wire.all are air test .medium sensitivity.cause at home.
small gold coin from 10cm
gold ring 10cm,same with coin.
4small gold coins from almost 30cm.
8 gold bracelets and one big gold coin from almost 60cm


I want offers for detecting jug at140.
or better coil offers that can detect targets have diameter bigger than 40cm at 1.5-2.5 meters.

and I have a coil houser .almost 44cm diameter.
offers for this housing.wire and turns please.

we buried jug.only homemade two box and lorenz 45cm coil detected them yet.

.

Do you have tested DP with 45cm Lorenz coil?

[1843]

If so, How is its result?

[Unregistered]

no I did not.their frequencies are different that they can not work properly.
I just wondered wire and turns.cause it is the only detector find it yet.accept two box.
