Features
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.
Package include
1 x Step down module (with heat sink and screws)
