Hello geniuses in this video I will show you how you can test Zener diode and LCD - tv LED backlight using an old light bulb

How to use a multimeter. Find out in this tutorial for transistors, resistance, voltage, current, continuity, AC, DC, batteries, frequency, diodes, LEDs, capacitors, temperature and much more.

1. Measure voltage

Measuring AC or DC voltage is done in the same way. The multimeter must be connected in bypass (parallel).

- Select the highest rating corresponding to the voltage to be measured (10 volts, 20 volts, 500 volts, etc.).

- Select the type of voltage to measure: alternating (V~ symbol) or direct (V= symbol).

- To measure an alternating voltage, set the central selector to the zone marked VAC, ACV or AC.

- To measure a direct voltage, set the central selector to the zone marked V, VDC or DCV.

- Measure the voltage using the red and black test tips.

- If the measured voltage is direct, put the minus (black) terminal of the multimeter in contact with the minus of the installation.

- Then contact the other terminal of the multimeter (red) at the location where you want to know the voltage: the measurement appears on your screen.

- If you want a more precise measurement (case of batteries), adjust the caliber of your tester to approach the value indicated on the device.

2. Measure a current

To measure current, the multimeter must be connected in series.

To take this measurement on a low voltage (battery powered) device:

- Select the highest rating corresponding to the current to be measured (milliamperes, amperes, etc.).

- Select the nature of the current to measure: alternating (symbol A~) or direct (symbol A=).

- Open the circuit at the location where you want to know the current intensity.

- Connect the two test probes to the two circuit break points.

This simple little tutorial shows how to use a digital multimeter for beginners including the basic functions. I show in detail how to measure direct and alternating voltage, measure resistance and also how to test a diode and do a continuity test.

these are the basics for any DIYer in electronics and electricity because often to create a circuit or check the correct functioning of a circuit you need a multimeter but this is not easy for someone who has not done of electronics in their schooling or their professional career, it is in this perspective that I put this little tutorial because it is aimed at everyone, especially beginners.

To start in electronics and electricity I advise buying a multimeter which has the most options, but not necessarily the most expensive because for an amateur like me making it profitable is not obvious, currently we have the choice.
