add electronic circuit to your multimeter and get an amazing option
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

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.
- Read the intensity on the dial of your multimeter.
