1. LED power indicator.
2. Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value).
3. Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate!

Voltmeter calibration method
1.Onboard voltmeter shows that the output voltage, long press the right button 2 seconds to loosen, voltmeter, and the output voltage indicator light "OUT" synchronous flash, at this time into the output voltage regulation mode; Similarly, when the input voltage IN the voltmeter display, long press the right button 2 seconds to loosen, voltmeter, and the input voltage indicator light "IN" synchronous flash, at this time into the input voltage adjustment mode;
2.Light touch button on the right side, the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit of voltage is less than 0.1 V, so you need to press the 1-5 consecutive can see the voltmeter change 0.1 V, the concrete continuous button several times depends on the current display voltage, current shows that the higher the voltage, the fewer the number of press
3.After the voltage adjustment, long press the right button for 2 seconds, release, to exit the output voltage calibration mode, all the parameters set to automatically power down saving.
The DC/DC buck module applications the input voltage is higher than the output voltage of the buck field, such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV，portable instrument power supply，telecom/networking equipment,24V vehicle notebook power supply,industrial equipment buck.12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V etc.
