After winding inductance coil measure the measuring instruments, according to him, damping resistor must be installed. Check resistance values are also being wrong color.Little tip everytime measure resistance sometimes color is going wrong and misleading...

THANK you  FOR THE REPLY.for resistors :i use pr1:470k.r5:680ohms-1watt .r6:1k.they are good.but when i sweep any metal on my coil it's detected with a continuous sound .i think it need some adjustement Would you please clarify how to adjust it ?.many thanks

DELTA PULSE 2 settings : Mybe HELPFULL....   Wink  important ( In running, the device applies an alternating high voltage amplitude
up to 1000 volts dangerous to humans. Therefore, it is desirable to take precautions, do not touch the connector pins of the coil and the legs of the FET switched device. )


1) Hold the face before turning on your device and search the title of "Power"

 (NOISE) received a minimum resistance of the pot.

 2) Turn on your device.

 3) "Power" (NOISE) Learn pot to the maximum resistance

 4) "Gain" (GAIN) to center the pot

 5) "Signal" (SIGNAL) received a minimum resistance of the pot.

 6) "Sensitivity" (SENS) to center the pot.

 7) "Threshold" (TRSHOLD) to center the pot.

 Cool In this case must come constantly warning sound from your device.  Here

 Article 10 is ok as you can now.  If the warning sound can not be arrived at 9am.

 Read agent.

 9) If you do not hear sound from your device "Gain" (GAIN) pot slowly

 towards the minimum of resistance until the sound.  Sound

 When you start coming now Article 10.  If the "Gain" (GAIN)

 sound from the device while you bring up the pot to a minimum of resistance
 your device is damaged.

 10) written so far everything is ok so the pot setting devices

 If you currently make cooing sounds as disconnected devices "Reset" (TINA)

 briefly press the release button.  So far the problem or Article 12 of the

 You can now.  If your device does not sound any time interrupted or cut

 then again if they start crowing apply Article 11 itself.

 11) "Reset" (TINA) the state does not cut any audio device that you press the button

 or cut off after a short time if it begins to spontaneously sing "Gain"

 (GAIN) Turn off your device in the direction of the pot a little maximum resistance

 5-10 seconds then turn it back on.  Process step 8 starting from operations

 Repeat.

 12) "Reset" (Tina) You press the button and the sound was cut up everything here

 ok.  Now we'll fine-tune your device.  This setting how thin

 You can do so if the device works fine.  "Threshold" our final pot slow

 slow "ticking" sound until he lower the threshold

 We begin.  When we leave our device "ticking" sound came from.  A while

 the "ticking" sound is automatically interrupted again until it is sound

 We translate.  "Knock, knock" sound continuously until "Threshold" (TRSHOLD)

 We reduce our value.  "Knock, knock" sound is continuously coming to start as soon as

 We leave.  Then the "Threshold" (TRSHOLD) our value from the constant "ticking"

 We turn our voices VERY slowly counterclockwise until interrupted.

 Sounds so as soon as the cut "the voice came from the future ha ha" we leave.  Is This

 If you catch the point of how sensitive the device works so sensitive.

 So far everything is okay if you geçebilis process step 13.  If

 "Threshold" (TRHOLD) value even when you reduce to a minimum "ticking"

 If the sound is constantly breaking self "Threshold" (TRHOLD) maximum value

 take the value "Gain" (GAIN) to the pot a bit minimum of resistance

 The correct translation.  Again began to hear sound "Reset" (TINA) button

 Press and ischemia step of 12 'to continue as from.

 13) Now we are ready to use your device in the air.  In this case, if small

 Make the air a little test.  If the single currency is a less than 25cm

 Review your actions if you perceive from again.

 14) So far everything is ok your device search titles slow

 15) Make sure that there is no metal in the earth's surface, then

hello, can anyone explain what bar1 bar2 and bar3 means in the attachment??

one more question:
 LCD reset is needed every time you power on the metal detector or just the first time?

Hi Mazari

When I build the DBP2010 I had the same problem with very poor detection, after spending hours I finally found that there was a cats whisker (very small short between two tracks) as soon as I got rid of it the detector was working 100% so look very carefully with a magnifying glass and clean any suspicious looking item between your tracks.
