The voltage drop test

For a complete circuit diagnosis, you need to check for a circuit break, a short circuit, or a violation of the soldering of the chip output. To do this, use a diode continuity test (measurements of the voltage drop in the circuit). We study in detail several types of measurements with a multimeter on the soldering course at Bgacenter.
