    The (device under test) or small power supply board has 4 pins where the first 2 pin are channel 1 (having +ve & -ve value) and last 2 pin are channel2 (having +ve & -ve value). From the 2 channels , I need to check the board are working or not working. So plan to use voltage divider plus the variable switch, potentiometer and 2 led to check device under test are good or bad.

    Can you help me on how to draw the circuit for the above matter?
