IN+: connect IN+ to your Input Positive
IN-: connect IN- to your Input Negative
Out+: connect OUT+ to your Output Positive
Out-: connect OUT- to your Output Negative
1. There are two buttons on the left side of the voltmeter, one is for input voltage display and the another is for output voltage display. You can press one of the two buttons to choose the voltmeter to display input voltage or output voltage.
2.There are output voltage adjustment "-" button for decreasing output voltage and output voltage adjustment " +" for increasing output voltage.
3. There are two LED indicators on this converter board, including the red LED and the green LED. The red LED will light on when you measure input voltage and green LED will light on
when you measure output voltage.
4.It is low power consumption, and has terminal and retain the wire bonding wiring point. And If you remove the P3 jumper cap, the voltmeter will shutdown.
