Objectives of this experiment:
To use the o-12 VDC variable power supply trainer, first turn the part P1 to the 0V setting. Now connect the output leads, observing polarity, to the item to be powered with a Voltmeter across the output leads, which are already connected to the item to be powered, slowly increase the voltage by adjusting p1 until the correct operation voltage is indicated on the voltmeter. The voltmeter can be disconnected as long as you do not change the setting of P1. The power supply will stay on the correct voltage each time you use it to the power that item. If you want to power a different item, repeat the above process.
