Input Voltage Must Be 1.5 V Higher Than The Output Voltage, No Boost 2. Do Not Reverse The Input And Output Interface 3. Keep Output Under 2A (Or 15W), And Use A Heat Sink When For A Long Time Working How To Calibrate The Digital Tube Voltmeter (Optional Steps For The Person Who Need A Highly Accurate Voltage Value) 1. Short Press The Left ''On\/Off'' Button To Start Up The Digital Tube Voltmeter. Long Press(\u0026gt;1S, 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(\u0026gt;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)3. After Calibration, Long Press(\u0026gt;2 Seconds) The Right ''Mode'' Button To Preserve The Adjusted Value(No Loss With Outage) And Back To Normal Voltage Display.
