How to Calibrate the Digital Tube Voltmeter
(Optional steps for the person who need a highly accurate voltage value)
➤Short press the left "ON/OFF" button to start up the digital tube voltmeter. Long press(>1s, <4 seconds) the left button to shut down the digital tube voltmeter.
➤Long press(>4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0).
"IN" indicator lights = input voltage measurement calibration starts. Then, long press(>2 seconds) the right "Mode" button, "OUT" indicator lights = output voltage measurement calibration starts.
Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V,
you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V)
➤After calibration, long press(>2 seconds) the right "Mode" button to preserve the adjusted value(no loss with outage) and back to normal voltage display.

Kindly Note:
☑ Input voltage must be 1.5 V higher than the output voltage, no boost
☑ Do not reverse the input and output interface
☑Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat sink (10W output above),
because it is the step-down module, in order to ensure stable output Set,please keep the minimum 1.5V differential.

Package List:
✔6pcs x DC-DC Buck Converter Module

• All use SANYO solid-state capacitors, 36u thick circuit board, high-Q value and high-power inductor with output LED indicator lights
• Product parameters: The input voltage is DC 3.2-35V, the output voltage is 1.25V-30V (continuously adjustable, the input voltage must be 1.5V higher than the output voltage), the maximum output current is 3A, the conversion efficiency is 92% (maximum), the output ripple is less than 30mV, the switching frequency is 65KHz, and the working temperature is -45°C to 85°C.
• Note: This is a voltage reduction module. The input and output connectors cannot be reversed. The input voltage must be higher than the output voltage. It is recommended to use a current of less than 2.5A for long-term work. If it exceeds 2A, a heat sink (output of over 10W) should be added. When using it for the first time, the potentiometer must be turned counterclockwise at least 10 times.
• IN+input positive pole, IN - input negative pole
• OUT+output positive pole, OUT - output negative pole, please note that the input and output cannot be reversed, as it may burn out if reversed!
• Application: The LM2596 step-down converter can be used in fields where the input voltage is higher than the step-down output voltage, such as batteries, power transformers, vehicle mounted voltage stabilizers, and system operating voltage testing
