Summarize the following:
Analog multimeters have a needle behind a glass window, which moves to indicate the result. Typically, there are three arcs printed behind the needle. These are three different scales, each of which is used for a different purpose:  The Ω scale is for reading resistance. This is typically the largest scale, at the top. Unlike the other scales, the 0 (zero) value is on the far right instead of the left. The "DC" scale is for reading DC voltage. The "AC" scale is for reading AC voltage. The "dB" scale is the least used option. See the end of this section for a brief explanation. Look carefully at the voltage scales, either DC or AC. There should be several rows of numbers beneath the scale. Check which range you have selected on the dial (for example, 10V), and look for a corresponding label next to one of these rows. This is the row you should read the result from. Voltage scales on an analog multimeter work just like an ordinary ruler. The resistance scale, however, is logarithmic, meaning that the same distance represents a different change in value depending on where you are on the scale. The lines between two numbers still represent even divisions. For example, if there are three lines between "50" and 70," these represent 55, 60, and 65, even if the gaps between them look different sizes. Look at the range setting that the dial of your multimeter is set to. This should give you a number to multiply the reading by. For example, if the multimeter is set to R x 100 and the needle points to 50 ohms, the actual resistance of the circuit is 100 x 50 = 5,000. The "dB" (decibel) scale, typically the lowest, smallest one on an analog meter, requires some additional training to use. It is a logarithmic scale measuring the voltage ratio (also called gain or loss). The standard dBv scale in the US defines 0dbv as 0.775 volts measured over 600 ohms of resistance, but there are competing dBu, dBm, and even dBV (with a capital V) scales.
