Create similar products the most affordable best-selling LM2596 module with voltage display Features 1 Input voltage range:4-40VDC 2 Output voltage range:1.25-37VDC adjustable 3 Output current:2A 4 voltmeter range: 0 to 40V error ¡À0.1V 5 Input reverse polarity protection 6 Built in output short protection function 7 Built in thermal shutdown function 8 L x W x H =6.1*3.4*12 cm 9 Weight: 22g 10 LEDdigital voltmeter tube the accuracy is adjustable function can be aimed at your multimeteradjustable accurate 11 Press the rightkey to let the display show the input or output voltage when the right OUT led light it shows output the left IN led show input (1) Output voltage calibration steps Step 1 adjust the right button so that OUT LED lighted the voltmeter shows the value of output voltage Press the right button for more than 2 seconds release voltmeter and OUT LED flashes in synchronization so that youenter the output voltage calibration mode. Step 2 press the right button (normal speed) the voltage value is adding up a unit Press the left button minus a unit Due to a unit is less than 0.1V the minimum voltage display to 0.1V so you need to continuously press 1-5 times to see the voltmeter change 0.1V how many times voltmeter change 0.1V by pressing the key depending on the current display voltage the higher the voltage the fewer the number of press Step 3 press the right button for more than 2 seconds release to exit the output voltage calibration mode All parameters set to automatically power down to save (2) Input voltage calibration steps Step 1 adjust the right button so that IN LED lighted the voltmeter shows the value of input voltage press the right button for more than 2 seconds release voltmeter and IN LED flashes in synchronization so that you enter the input voltage calibration mode Steps 2 and 3 consistent with the output voltage calibration method
