6812 How to set up the power supply.

Notes on power supply: Before plugging in the power supply take the 120v plug (it comes separately) and tint the bare ends of the cut end. To do this take the soldering iron and let it warm up. It gets very hot and can burn things. When done do not forget to UNPLUG it. When the iron is hot melt some solder onto the tip of it (only need to do this to a new iron).

Touch the hot iron to one of the bare wires, then a few seconds later touch the solder to the now hot wire (make sure the wire you are tinting is not plugged into the wall socket). The solder should melt into the wire and cover it. Not too much solder it needed. Withdraw the iron and solder, wait a minute for the wire to cool. Do this to the other bare wire. When done screw it into the L and N connector of the ac input of the power supply. power supply

Now you can plug it in. Check to see that the output is 5 volts. Take the voltmeter and set it to measure 20 dc volts or less. The black probe goes into the connector labelled COM and the red one into the one labelled v (this is on the voltmeter). Now measure the voltage of the power supply by taking the red probe and touching +v on the power supply. Take the black probe and touch -v on the power supply. It should read between 4.8 and 5.2 volts. If not you can adjust it via the v adj on the power supply. My finger is pointing to the adjustment knob in the picture. power supply

With this done you are ready to use the 5v supply as needed in our labs. Hit "back" on your browser to return.
