Step 1: Adjust the right button to light up "OUT" LED, and the voltmeter shows the output voltage. Press the right button for more than 2 seconds and release it to enter the output voltage calibration mode. LM2596 DC 4.0~40 to 1.3-37V LED Voltmeter Buck Step-down Power Converter Module is a high-quality product that comes with input voltage range of 4-40VDC and output voltage range of 1.25-37DC adjustable. This module has output current of 2A and a voltmeter range of 0 to 40V, with an error range of +-0.1V. It features built-in output short protection function, input reverse polarity protection, and thermal shut down function. The LED digital voltmeter tube comes with adjustable accuracy function which can be aimed at your multimeter accurate. To adjust the accuracy, follow these steps: Input voltage calibration steps: Return Step 2: Press the right button to add a unit, and press the left button to minus a unit. The minimum voltage display is 0.1V, so you need to press the button 1-5 times to see the voltmeter change 0.1V. How many times the voltmeter changes 0.1V depends on the current display voltage, the higher the voltage, the fewer the number of presses. Step 1: Adjust the right button to light up "IN" LED, and the voltmeter shows the input voltage. Press the right button for more than 2 seconds and release it to enter the input voltage calibration mode. Shipping and handling: We are not responsible for customs duty or import tax.
