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) 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 you enter 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.

Usage:
(1) adjust the “voltage potentiometer” so that the output voltage reaches the value you want.
(2) use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the “current potentiometer” so that the output current reaches a
predetermined overcurrent protection value. (For example, the meter displays the current value of 4A, then you
can use the module to a maximum current of 4A)
(3) Connected to the load.
2、Use as a battery charger
Usage:
(1). Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh,
then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA)
(2). Under no-load conditions, adjust the “Voltage potentiometer” so that the output voltage reaches the float voltage;
(if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)

gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned
off, the green light is on, which means that the battery is fully charged)
(5).connected to the battery charge.
(1,2,3,4 steps as: Output is unloaded, do not connect the battery)
