    Tesoro Golden umax factory settings of trimming resistors

    Hello, I need help. Can anyone tell the factory settings of the variable resistors on the PCB? It is necessary to restore the factory settings.
    Who up to knocked down all the settings, and I doubt that the metal detector works correctly.

    Guys if you have a tesoro golden umax in which no one twisted anything on the circuit board. Please make measurements of the resistances on all the variable resistors located on the printed circuit board. I will be very grateful.

    To get an accurate reading you would have to unsolder the pots.

    Do not necessarily solder. Can be measured directly on the printed circuit board. It is necessary to measure from the middle point to the extreme. That is, you get two measurements from each of the four resistors. I'm on my golden umax, then I would have set everything up as well.

    That's what I need. Made a screen. And the best option, of course, is to look at the oscillograms from the control points on the printed circuit board. Although I certainly understand that this is not a chance. But still,,,Click image for larger version.
