I was looking at a DC Power Supply for diode testing. And I noticed Fine and Coarse dial for Voltage and Current. What are these. What does each do.

Like the names imply, the fine and coarse controls will work together to adjust the outputs that you want. For instance, if you wanted to set a voltage output to five volts, you would first put the fine control to its center position and then use the coarse control to get as close to the five volt setting that you want.I was looking at a DC Power Supply for diode testing.
