The same applies to milligrams, grams, and kilograms for mass. Remember, this gallery is meant to be a general guide; if you do not see your model of multimeter pictured here, your best bet is to consult your specific multimeter's manual. For example, if your circuit is powered by a single 9V battery, it probably doesn't make sense to select the setting for V, and 2V would be too low.

How do I measure resistance? The same applies to using a multimeter.
Check your multimeter's manual if you still can't figure out what one of the symbols means. How do I measure current? To learn more about voltage, current, and resistance in series and parallel circuits, check out the References tab.
Electricity from wall outlets is very dangerous and can be fatal. Like the squiggly line, mulitmetro might see this next to or above a V or an A. Notice that it only has two sockets, and there is a switch to toggle between AC and DC measurements which is unusual.
Digital Multimeter DMM basics tutorial
Because of this variety, and because the feature is not required for most Science Buddies projects, we have not included directions here. Ttorial wire on the inside might have completely burned away, and no longer be visible. What can I do with a multimeter around the house? Most multimeters have a knob on the front that lets you select what you want to measure. For example, you probably know that a meter is a unit of distance, a kilometer is one thousand meters, and a millimeter is one thousandth of a meter.
Remember that the primary purpose of a multimeter is to test circuits and electrical components in an experiment or science project that involves electronics.
How to Use a Multimeter
All of them have a single "ground" socket for the black probe. Always wash your hands carefully after handling solder, and check your local waste disposal guidelines to see if there are special rules about disposing of lead as hazardous waste. The Fuel Cycle of the Future.
This manual-ranging multimeter has additional features capable of measuring capacitors and transistors not covered in this tutorial. In addition to the availability of a true RMS meters, similar refinements of the other basic measurements are also available in some instances.
How to Use a Multimeter
Use a multimeter to find out how well these different liquids conduct electricity. Reproduction of material from this website without written permission is strictly prohibited.
This function is used to test a diodewhich is like a one-way valve for electricity; it only lets current flow in one direction. Digital multimeters are widely used and very useful items of test equipment. This auto-ranging multimeter is unusual in that the probes plug in to the back side. Don't worry if this seems confusing; this table will help you keep track:.
You might be confused by all the symbols on the front of your multimeter, especially if you don't actually see words like "voltage," "current," and "resistance" spelled out anywhere. This is a manual-ranging multimeter with typical settings for DC voltage, current, and resistance, It can also measure AC voltage and has a continuity check. Fuses usually look like small, glass cylinders with metal caps on the end and a thin wire running down the middle:.
Use fuel cells to store energy produced by solar panels for use when it's dark out, and use your handy multimeter to keep track of your power generation. The multimeter supplies its own small amount of current, which allows it to measure the resistance.

Diode check triangle with some lines through it: The low-current socket is also used to measure voltage and resistance. It also has a "Logic" test function for measuring digital circuits tutirial covered in this tutorial. You can also browse our multimeter gallery to see labeled pictures of different multimeters. Continuity check series of parallel arcs:
