Product Description Voltage Regulator Step-down Power Converter Module DC 4~40V Adjustable Board LED Features: *LED digital voltmeter tube, adjustable precision function, can be adjusted accurately for your multimeter *Press the right button to display the input or output voltage *When the "OUT" indicator on the right is on, the output is displayed, and the "input" LED input is displayed on the left side *Made of high quality material, durable and practical to use *100% brand new and high quality Specifications: *Input voltage range: 4-35VDC *Output voltage range:1.25-35VDC (adjustable) *Output current: 2A *Voltmeter range: 0 to 35V, error ±0.1V *Input reverse polarity protection *Built in output short protection function *Built in thermal shutdown function *Dimension: 6.1*3.4*12 cm(Approx) *Net Weight: 22g(Approx) How to Use: (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.
