دائرة فلتر لحماية الملتيميتر | Filter circuit for multimeter protection

This video explains step-by-step how to design a filter circuit to protect the power supply of a 9V/6V multimeter (DT-830D DIGITAL MULTIMETER or XL830L, FLUKE-115 UNI-T) from sudden voltage spikes and ripples caused by the J5019 boost converter when the battery voltage drops. The goal is to boost the voltage of a 3.7V lithium battery to 9V to power the multimeter after modifying the original non-rechargeable battery to a rechargeable lithium battery. We will cover: The operating principle of the circuit Does the module have protection against low battery voltage? The causes of ripples and sudden voltage spikes when the battery voltage drops Designing a filter circuit using capacitors, Zener diode, and resistors to reduce noise and protect the device from voltage spikes Testing the output voltage with a low module power supply voltage A practical test of the circuit after modification on the multimeter This video is suitable for engineers and hobbyists interested in electronics and portable power, providing a practical demonstration of how to improve device performance after battery modification. It also addresses the issue of replacing a 9V or 6V battery.
