Parameters：
1. Input and output voltage display, voltage error ±0.1V, input range 4-40V, output 2-36V (Note: to ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4V)
2. Output current display, current error ± 0.05A, maximum current 3A (recommended: under high current use conditions, the output voltage should be reduced to use)
3. Touch the button to switch the input and output voltage or current display, LED indicators indicate the input or output voltage
4. With power-down memory function, the last measured input, input voltage value or current value is displayed after power on
5. Input and output terminals using terminals and pads, convenient wiring and welding line
6. Input voltage 4.0-40V (input voltage must be more than 1.5V higher than the voltage to be output)
7. Adjustable output voltage range 1.25V-36V continuously adjustable (input voltage must be higher than the voltage to be output by about 1.5V)
8. The maximum output current can be as high as 3A, the normal stable working current in 2A, higher current need to increase the heat sink
9. Using 4-digit digital tube display, digital tube voltage display LED 4 bit for U (indicating voltage V volts), current display LED 4 bit for A (indicating current A amps)
10. 150KHz internal oscillation frequency, belonging to the second generation of switching voltage regulator, low power consumption, high efficiency
11. Switching indicator are red

How to adjust the accuracy?
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.
Note:
Some customers report: "The module can not be adjusted, the output voltage is always equal to the input voltage." When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 20V.
