DTI-Puls
Metal Detectors of the DTI-Puls-Series are working on the basis of Puls-Eddy-
Systems. Data handling works completely digital. The system is based on two proc-
essors. The first processor is handling the measurement and the calculation of the
datas. The second processor is responsible for management, display, communication
and operating.
Measured data are displayed on a graphic display with 240 x 128 pixel, and via a
built in speaker or headphone. The detector can be driven with several coils. A
menue showing the types of coils is available.
The system works with online metal discrimination. The display shows recognized
objects in different kind of ways.
The software may be adapted according the newest versions. The hardware does
have several plugs für future expandations. The detector can follow technonogical
improvements for a longer time.
The system is prepared for following future expandations:
1. Multi language menues and displays
2. Wireless headphones (already available)
3. Wireless data communication
4. Data recording (Recording of the search on MMC-Card for later analyses on
PC)
5. GPS (Position of searching area)
With a new generation of detectors new problems come up. The user might be erri-
tated by the many possibilities of adjustments.
Only by testing with different objects in the air and in the ground kann help. Changing
parameters will cause different behaviour of the detector.
After a short time you will recognize that handling will not cause problems any more.

Assembling
After opening of the Aluminium-Box you will see the electronic unit of the DTI-Puls-
Instrument, the 28 cm – coil, a manual and a checklist. Take this parts out. Below the coil you
will find the headphone and the battery charger. Furthermore you will see the charging regula-
tor, a cable and rods for the coil.
Mount the coil to the lower rod. Assamble the rods and adjust the length according your body
size. Turn the cable around the rod and put the connector into the female connector of the
electronic unit. Please obey that the connector fits tide.

Back to Menue
Leave Menue
Please obey that a reaction time of up to one second can happen, if you go back to a
menue or if zu leave a menue. After adjustments in the main menue the system al-
ways takes a few seconds until it is stable again after leaving the menue.
Please obey that you need to make a REFERENZ after leaving the main menue.
That has to be repleyed when the coil is near the ground.
The detector has a demonstration mode. This mode allows you to become familiar
with the keys and its reactions. The detector has connectors on both sides. Below the
ON/OFF-switch is the coil connector. It has a protecting cap prohibiting coming dirt
and moisture in it. Please put this cap always on if you don’t use the instrument. Al-
ways obey to fix the connector tide when you connect the coil. A bad connection
causes uncontrollable currents which can destroi the power amplifier.
On the other side are the load- and the headphone connectors and the communica-
tion connector. Headphones with a minimum impedanz of 32 Ohm and 6 mm con-
nector can be used. It should have the possibility to adjust the loudness. The internal
loudspeaker will be switched off when pugging in the connector. The input for the
charger is a 2.1 mm connector. More unter point charging.
The communication connector is a Sub-D9 female connector. This connector will be
necessary for the future software expandation for connecting a personal computer.

Setting to Operation
Bevor the first use you should load the detector with the attached charger for 14
hours. Especially when you read a warning after the fist switching on.
If you start directly with the coil please obey the good fitting of the connector. Never
connect a coil when the instrument is switched on. The exeption is when you will be
asked for by the menue. See the chapter Changing Coils.
Look for a place where are not many big metal parts near by. In rooms television or
computers may not be switched on. The emissions of this instruments are being re-
ceived by the coil.
Switching on:
A beep will be produced. The condition of the rechargeable batteries will be checked. If the
rechargeable battery is not ready for operation a message will be displayed. You have to
switch off the detector for charging batteries.

DTI GmbH & Co. KG
If there is no problem with the rechargeable battery you will see the start logo. To-
gether with the start logo the detector starts sending pulses. The start phases starts.

When showing the version number the detector is waiting for ist starting require-
ments.
You have three possibiities for starting.
F1: Normal start with coil. You press F1.
F2: Start in demonstration mode. No coil is neccessary.
F3: Reset – Set the detector to factory settings.
Seite 9 von 31

DTI GmbH & Co. KG
In case of a problem with the communication of both internal processors it can hap-
pen that wrong datas are being used. That can happen because of some influence
from outside of by switching on and off in a short time by accident. In this case use
F3 – reset.
Coil neccessary. System has been startet without coil. Please switch off.
When you choose a start with coil without having connected a coil this message will
be displayed. The system switches to the demonstration mode.

DTI GmbH & Co. KG
In the start display you are watching the active program (0), the puls power (1) and
the type of coil according to the model (2). In the right the current state of battery ca-
pacity. The graphic continuously writes 200 measured data. Above the zero line non
ferrous and below the zero line ferrous metals are being written.
The range of number display is from 0 to 1000 showing the measured signal in live
time. FE is the ferrous and NE the non ferrous metal measured. The non ferrous
metal is been shown in reduced form above the numbers. Below the numbers the
common metal signal is displayed by a bargraph. On the left of the display you will
see the spectrum of measured signal. With help of the spectrum on basis of 9 spec-
tral lines you are able to do an additionally analysis.
Below the ractagle lines there is a line showing parameters which can be changed
online. Also in this line short information are being shown. The last line shows the
actual menue of the pushbuttons. The detector is ready for working immediately, but
it will take 1-2 minutes until coil battery and electronic are termally stable. By pressing
the pushbutton “REFERENZ” the momories are loaded new and set by factory pa-
rameters. All driftings will be compensited. If you do a reference above a metal ob-
ject, this object also will be compensited and can not be detected any more.

DTI GmbH & Co. KG
The detector has the possibility to change parameters online during searching. This
is comparable to the analog function of a potentiometer. So you are able to change
the most important paramters without calling up a menue. Press the pushbutton ‘F3’
e. g. ‘F4’. The number above the key will change accordingly.
After starting always appears
Tongenerator / Tone Generator:
By setting the Tone Generator you adjust the threshold of the tone. You adjust the
strengs of the signal when the first click shall appear. After start always 150 is setted.
The higher you choose the value the smaler the signal strength of a measured object
may be. Generally a click rate of 1-2 will be adjusted without signal.
You press ‚F1’ and as an active parameter you will see
Suchspeicher / Searching Memory:
The main memory of the system has been devided in several layer and sectors. Out
of this memory the searching memory will be generated. There are 1-33 chooseable
searching memories. The detector always starts using the searching memory 11.
This aproves that a detection is possible using all types of coils. The smaler the num-
ber of searching memory the more sesitive the detector reacts on smallest objects.
On the other hand that can mean that you will have a permanent detection even in
50 cm hight above the soil and doing a ‘REFERENZ’ will reduce the range of values
dramatically. You have to reference always at the place of using the detector.

DTI GmbH & Co. KG
Depending on the soil concerning the searcing depth it is not possible to give a state-
ment. The settings of the searching memorie will not be stored in memory. So it al-
ways has to be set individuelly. The factory setting is a good average value for 28 cm
– 50 cm coils.
You press ‚F1’ and as an active parameter occurs
Audioverstärker / Audio Amplifier:
The audio amplifier multipies the click rate of the tone generater by its value. The
maximum value is 16. If you have a signal with 10 clicks per second the click rate will
be multiplied to 160 when amplifying by maximum. Accordingly the rasing speed of
the audio signal and its sensitivity is rising.
You press ‚f1’ and as an active parameter occurs
Diskriminator / Discriminator:
The discriminator has a range of 1-5. Because of the high sensitivity of the detector it
is not possible to distinguish smallest and biggest objects in the same matter. The
discriminator is based on an algorithem for alloys. It equals a balance weigher. The
possibility of discrimination is based on the characteristics of the metals. Deciding are
its conductivity, shape, alloy, position and distance. Furthermore die type of soil is
important. The electromagnetic field may be influenced. Also there is an enormous
amount of soil behind the detected object which also will be detected and measured.
Very often a bigger distance to the ground or tipping up of the coil can help. The post
important parameter is that the detection for a defined identification has to be repro-
duceable. The sum of different characteristics of different objects may produce a
similar sinal to gold. If you imagine how many unknown characteristics have to be
considered that is not astonishing. Therefore tests with different objects and metals
are necessary. Bigger or massive non ferrous metals will always show a negative
result in the air if they are not “alloyed”. Even if pur gold will be “alloyed” in the soil by
salts cristals or smallest objects.
In setting 1 the discriminator has the strongest filter. A golden ring (333, 485) will be
detected very sure. After start the discriminator setting is 2. The spectrum is working
independent of the discriminator setting and can help when testing and finding set-
tings.
You press ‚F1’ and as an active paramter occurs
Seite 13 von 31

DTI GmbH & Co. KG
Objektgröße / Object Size:
The parameter Object Size allows filtering of small to medium objects. This is abso-
lutely necessary on minerelized soils. Especially for coils of sizes 50 cm to 200 cm an
adaption is necessary. Because of the high penetration depth and because of that
the big volume of soil a rising of the Object Size is mandantory. Without this adaption
the range of value will be overloaded. The range of value 1 – 200 has to be adapted
right at place.
You press ‚F1’ and as an active parameter occurs
Suchempfindlichkeit / Searching Sensitivity:
The Searching Sensitivity is a sensitiv parameter and should only be used for very
low signals. When the audio amplifier is set to maximum and the searching sensitivity
will be rised the searching amplifier will be multiplied by the audio amplifier. This re-
sults in very fast detection signals. The reference (Referenz) has to be made very
carefully. Range of Searching Sensitivity is 1 – 8.
You press ‚F1’ and as an active parameter again occurs the
Tongenerator / Tone Generator.
As being seen out of this discription of parameters some exercise is necessary to
understand the reactions of the detector. You always should first use this parameters
before rising the puls power. Bigger puls power also means bigger penetration depth
and volume of soild under the coil.
You press ‚F5’ and the basic menue option will be displayed.

Menue Options
You press ‘F4’ and the Audio Menue will be displayed.
By the pushbutton F1/F2 you choose the function. By the pushbutton F3 you enter for
changing this parameter. By the pushbutton F1/F2 you change the value. By the
pushbutton F3 you save the setting.
If you have chosen to change the parameter by F3 you need to save by F3 because
otherwise you are not able to leave the menue or to make other changes.
By F4 you get back to the menue. By F5 you get back to the detection display. This is
the way to leave all menues.

1. Audioverstärkung / Audio Amplifier
This parameter is identical with the active parameter and can be changed at
this place also.
2. Lautsprecher / Loudspeaker
The internal loadspeaker can be switched of independently. Also the connec-
tor for the headphone is out of order when switched off. This function is to be
used in connection with the audio transmitter.
3. Audiosender / Audio Transmitter
The detector has an option for an audio transmitter which allows a wireless
transmittion to a wireless headphone. The autio transmitter can be put in addi-
tionall. It always comes together with the GENESIS.
4. Tondiskriminator / Tone Discriminator
By ton discriminator you switch the audio gnerator to the discriminator. So you
only will have an audio signal when the discriminator allows. If you activate
this function you should obey the display in any case because you could miss
objects because of the threshold.
5. Beeper – Bediensignal
If you feel disturbed by the beeper you can switch it off. Warning signals will
not be switched off.
If you are back at the menue you can choose the menue Display by pushbutton
F3.

1. Skala Ziffern / Scale Numbers
This parameter changes the range of display of the number display. The range
up to 1000 will be devided by this value.
2. Skala Bargrafik / Scale Bargraph
This parameter changes the range of the bargraph. Discriminator and all metal
display do have the same value. You are able to equal the display to the tone
behaviour.
3. Skala Grafik / Scale Graphic
This parameter changes the display range of detection record.
4. Skala Spektrum / Scale Spectrum
This parameter changes the display range of the spectrum.
5. Autoskalierung / Auto Scaling
This parameter adapts the scale automatically..
6. Hintergrundbeleuchtung / Backlight
This parameter changes the backlight of the display. By this option enormous
quantities of power can be saved.
If you are back in the menue you can choose the menue Coils (Spulen) by F2.
Seite 17 von 31

DTI GmbH & Co. KG
Here you choose the type of coil used. The puls power will be adapted for the coil
automatically if the setted power is too high. The type of coil has been printed to the
coil lable e. g. can be recognized by the diameter.
If you select the proper coil and press F3 this type will be stored. If you leave the
menue by F4 or F5 you will receive a message.
You will now be able to change the coil when the detector is switched on. Only if you
see this message, changing is allowed. Afterwards the instrument only needs some
time for stabelizing the coil. If you change from a higher power coil to a lower power
coil the power will be adapted, but not rized again automatically if you go back to a
higher power coil. So you should store the settings before changing.
