Coil description

The special coils are made from constantan resistance wire (available on eBay) wound on 9 mm wooden dowels as shown in the photos. It is important that the impedance of the wire matches that of the generator, so for the recommended model you will need about 3.2 metres of AWG32 gauge wire for each of the coils. It is important that the wire is the insulated type; this is usually done by enamelling or varnish. If you have any problems sourcing the wire do let us know by using the contact page; I am sure we will be able to help The secret is to loop the wire back on itself before winding it tightly onto the dowel. You are therefore effectively only winding 1.6 metres and producing a perfect double helix. The dowel should have 2 small holes drilled around 25 mm apart to secure the winding which can be held in place using the ends of a wooden cocktail stick. 

NOTE: It is imperative that constantan wire is used for signal generator or Phone App connections  to prevent them being damaged.

The video below goes through the process of  making a coil.

 The constantan wire is coated with enamel or varnish, both of which will need to be removed in order to get a good connection (rubbing gently with fine sandpaper works well). It is worth checking the final result with an Ohmmeter or continuity device. 

The DCT is driven by a signal generator that has to have a frequency range up to 10 MHz and preferably be dual channel, to enable 2 people to be treated simultaneously. We use the FeelTech FY3200 it is well constructed, easy to use and readily available from eBay at a very reasonable price.  

 If 2 coils are used  they can connected to the outputs of the signal generator labelled CH1 and CH2, using the two leads supplied,  cut off the bnc plugs and directly connect the wires to the coils using a 3 Amp connector strip. 

Although the generator may seem complicated we only need to use its most basic functions which appear as default settings; so if in doubt just switch it off and then switch back on again. When the machine is first switched on it will default to: 

                                  MF= 0010.00000kHz
                                AMPL= 10.00V SINE 

This setting is perfect; all that is necessary is to dial the chosen therapeutic frequency for each channel. This is achieved by first choosing the output CH1 or CH2 using the appropriate output buttons. Channel 1 corresponds to the main frequency shown on the screen as MF and channel 2 corresponds to the secondary frequency shown on the screen as SF.When the green lights are illuminated the output is on when extinguished the output is turned off. 

To dial a particular remedy consult the therapeutic frequency table. The numbers given will all have a decimal point which corresponds exactly to the decimal point on the display. So for example the number 531.316 should be dialled to look like the number on the screen. By using the arrow buttons you can move the underscore left and right to adjust each digit using the large blue/white ADJ knob.
If you wish to save your settings press the SYS or MENU button once and *SAVE P_ON FREQ will appear at the bottom of the screen. Then simply press the white/blue ADJ knob and all the settings will be stored. Please note that on older machines the button is usually marked MENU whereas on newer models its now labelled SYS.
