✿ Main Features:

1. With voltmeter display, voltmeter error +0.1V, range 0-40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 3V)

2. Touch the button to switch the measurement input or output voltage, and an indicator light shows which voltage is being measured;

3. With the power-down memory function, it will display the voltage value of the last measured voltage after power-on;

4. Press and hold the touch button for 3 seconds to turn off the LED display, and touch the button again to turn on the LED display;

5. With terminals, it is easy to use without a soldering iron, and the soldering wire connection points are reserved;

6. The maximum output current can be as high as 2.5A;7. At present, the switching indicators are all red
