ИЗМЕРИТЕЛЬ ЕМКОСТИ АВТОМОБИЛЬНОГО АККУМУЛЯТОРА. Принципиальная схема. Часть 1.

Dear friends, there's an inaccuracy in the video's ninth minute: there shouldn't be a diode in the circuit in series with the battery. If you use a standard incandescent lamp as a load, keep in mind that the resistance of its filament at room temperature is significantly lower than the lamp's operating resistance. As a result, when connecting the lamp to the battery, a current surge occurs that can exceed the measurement limit of 30 amps (assuming we've reduced the shunt resistance by a factor of 10) and will definitely exceed 3 amps if the standard shunt is used. This can damage the ZB2L3 microcontroller. Therefore, the lamp should only be connected when warm. After watching the first part, if you're interested in this topic, I recommend watching the second part, which will help you choose the right connection diagram for a capacitance meter to a car battery and charger -    • Измеритель емкости автомобильного аккумуля...   Previously, we covered the following topics: 1.
