Problem: Article: Select the AC or DC voltage mode, depending on the circuit you want to test, which is indicated by a straight line with dots for DC or a wavy line for AC. Electricians and beginners tend to prefer digital multimeters because they are faster and easier to use. DC and AC are also commonly represented by DCV and ACV, respectively. Find out the regular voltage of the thing you want to measure and set the middle dial one level above that. So, if you want to measure a 120v outlet, set the dial to the AC side at 200v. Choosing a high range prevents damage from having too low a setting for a high voltage. Damage is uncommon when measuring low voltages, but if you set your multimeter to 20v and try to measure a 220v outlet, you might destroy it and have to replace it entirely. If your analog multimeter is set too high, the needle will barely move. Lower the setting if this is the case to get an accurate reading. If your analog multimeter is set a step too low, the needle will fling to the right. Quickly remove the probes from the connection to sever the circuit and prevent damage to your multimeter if this happens. Hold each probe by the protective plastic coverings and plug them into the corresponding terminals. This is best tested with a battery, if this is your first time using a multimeter, as the positive and negative sides are clearly labeled. It is sometimes recommended to attach the black probe but only touch the red probe to the positive terminal, as if there is an error you can quickly lift the probe and break the circuit. Look at the needle to see if it moves to around the middle of the display. There are various levels of voltages displayed behind the needle, so find the row that corresponds with the range you chose earlier. Take down the measurement, and consider repeating the test a few times to make sure the needle is reading accurately. Remember to start at a high range and work your way down. If the needle barely moves, select a lower range to get an accurate reading. If the needle flies off to the right, you need to break the circuit and select a higher range. If it flies to the right too hard, it might damage the needle, so try starting at a high range.
Summary: Select the AC or DC voltage mode on the multimeter. Choose a high range to start with, then lower it until the needle reads accurately. Attach the black probe to the negative terminal and the red probe to the positive terminal. Check the needle to see if it displays the right voltage, and make adjustments.

INPUT ARTICLE: Article: Whitefly traps are available commercially. They are usually bright yellow strips of sticky cardboard, staked or hung above plants. As you might have guessed from this description, they are easy to make yourself as described below. Note that these traps will only catch adult whiteflies, and young wingless nymphs will still remain on the plants and damage leaves. Combine this with other treatments for best results. If you'd rather make your own traps, start by cutting plywood or masonite board into strips roughly 12 inches (30 centimeters) long and 6 in. (15 cm) wide. This size should be suitable for most plants, but you may use smaller ones if you only have a small flowerpot or two to protect. Use any type of paint to make your traps bright yellow, on both sides. Adult whiteflies are attracted to this color. Petroleum jelly mixed with an equal amount of mineral oil or detergent creates a long-lasting sticky adhesive. Alternatively, use a heavy-grade motor oil or a commercial product such as Tanglefoot. Whichever substance you choose, be sure to coat both sides of the trap generously with a paintbrush, so any whitefly landing on the trap will be stuck. Hang them above your plants, or stake them in the ground near your plants. The stakes should be at the same level as the leaves you see the whiteflies feeding on. One trap for every two large vegetable plants or flowerpots is a good guideline. Hopefully, there'll be plenty of dead whiteflies on the trap, along with dead leaves or other debris that gets stuck to them. Wash with soap and water or scrape the traps regularly to remove these, and reapply the sticky substance so you can catch more pests. After the whitefly population is mostly dead, and you only see a few on the traps, take down the traps. Because the traps also have the potential to kill whitefly predators, they are not recommended for a low level infestation, unless the predators fail to keep the whiteflies in control.

SUMMARY: Purchase whitefly traps (optional). Cut your own traps instead. Paint your traps bright yellow. Coat both sides of the trap with a sticky substance. Place them above plants. Clean the traps periodically. Remove the traps when the whiteflies are mostly gone.

In one sentence, describe what the following article is about: You will need a large piece of duck cloth (you can generally purchase swaths of duck cloth that are 7 inches wide and 56 inches long.) You will also need scissors, a ruler, a sewing machine, fabric glue, a bag of feed corn, and a digital baking scale. You can also use a needle and thread if you do not have a sewing machine. Using your ruler, measure out 7 inches (17.8cm) at a time to make sure you are accurate. You should make 8 of these squares. Using either a sewing machine or a needle and thread, sew 3 of the sides closed. Keep in mind that you should be sewing 1/2 an inch in from the edge of the squares. Only do this on the sides that you have sewn up. Even though you have sewed these sides, gluing the extra fabric together will make it less likely that your bean bags will leak. Again, flipping your bag inside out makes it less likely that your corn will leak out. Place the feed corn onto your digital baking scale and add or remove corn until it weighs 15.5 ounces. Then put the corn into the bag. If you do not have a digital baking scale, 2 cups of feed corn is very close to 15.5 ounces. It may not be exact but it will be close enough. Fold the 12 inch (1.3cm) edges into the bag and hold closed. You can use a pin to hold the edges closed. Try to place your stitches as close to the edge as possible. Doing this will make the bag as evenly sized as possible.
Summary: Gather your supplies. Cut the duck cloth into 7-inch by 7-inch squares. Match 2 of the squares up so that they are perfectly aligned. Put a line of fabric glue in between the edges of the two squares. Flip your bag inside out. Add 15.5 ounces of feed corn to each bag. Measure 1/2 an inch in on the side that is still open. Sew the final side shut.

In the material settings, select what kind of material you are using. This will dictate the settings of the laser. For, example if you are cutting wood, the pressure will be stronger than if you were cutting foam. Click on the print menu. A preferences menu will pop up and ask you to choose the cutting method: raster or vector. If you are cutting your image press "vector print" and if you are engraving press "raster print". Press print and watch your image come to life. Don't move your material while it's being cut, otherwise, the image components won't line up. If you want to print multiple copies of the same item, replace the cut object with a new piece of material and press print again.

In one sentence, describe what the following article is about: Place the base of the blade in the slit of a magnetic holder, so the sharp edge of the blade extends past the magnet edge. This will make it easier to sharpen the blade without cutting yourself or dropping the blade. A strong, flat magnet may work instead. Sharpen slowly if using this device, to prevent the blade from falling off the magnet and potentially nicking you. Sharpen both blades using the steps below, one at a time.
Summary:
Use a magnet holder to pick up a blade (optional).
