1a. When you go to solder a component, you need to first wet your sponge, see if there’s any extra solder on the tip of the iron, and if so, wipe it off on the sponge. Then, turn on the iron and wait for the it to heat up and ensure its at about 750 degrees—usually the hottest setting. Then, test with the solder to see when it is hot, and then finally touch the iron to the component.

1b. Once you are done soldering, you need to wait a few seconds for the solder to cool and wipe off any extraneous solder onto the sponge. Then, place the iron back into the holster. After that, turn off the iron and make sure that the circuit is cool enough to touch before you pick it up.

2a. Before measuring current or voltage on the multimeter, you need to check that you are plugged into the right side, depending on which you want to measure. You also need to ensure that you are measuring DC power, rather than AC.
