Interestingly circuited actually zener diode test measuring instruments should have a property zener measurement of when you are secure, a voltage see better, but so far no measuring instruments equipped with this feature I have not seen though the circuit design a separate beauty measurement probe to be in shape to use is easy. Zener test circuit for ATmega8 microcontroller based on the indicators used 2 × 16 LCD also very practical and clever Inbox big thick felt-tipped pen used.
Circuit visionav source code of the code sprint pcb layout (zener_tester.lay) file spline scheme (zener_tester.spl7) and there are pictures about insurance options.
