Testing the Accuracy of a 30W Universal AC/DC Adjustable Voltage Power Adapter with a Multimeter
I used a multimeter to test the accuracy of a 30W Universal AC/DC Adjustable Voltage Power Adapter. I selected voltages of 3V, 4.5V, 5V, 6V, 7.5V, 9V, and 12V, and then measured the actual voltage output of the adapter using the multimeter.
The results of my testing showed that the actual voltage output of the adapter was very close to the selected voltage. For example, when I selected 3V, the actual voltage output was 2.98V. When I selected 4.5V, the actual voltage output was 4.51V. And so on.
In conclusion, my testing showed that the 30W Universal AC/DC Adjustable Voltage Power Adapter is very accurate. The actual voltage output of the adapter is very close to the selected voltage. This makes the adapter a reliable and accurate source of power for a variety of electronic devices.
- I used a digital multimeter to test the adapter.
- I tested the adapter in a variety of conditions, including with different loads and different input voltages.
- The adapter passed all of my tests with flying colors.
- I am confident that the adapter will provide accurate and reliable power for any electronic device that I need to power.
Voltages the power adapter plug supplies 3V 4.5V 5V 6V 7.5V 9V 12V The results indicated the two I tested were close to each other, and the measured voltage was close to advertised and sometimes a little above what was stated.
