How To Use a MULTIMETER (Volts, Amps, Ohms, Continuity)

This is a very quick version of a longer video I did on this topic a couple years ago. This is how to use an electrician's multimeter (tester) in around 5 minutes. You can watch the full version of this video here: kzread.info/dash/bejne/eYKmtcuMnaWYdLg.html

Many up-and-coming electricians have trouble understanding how to use the various electrical testers out on the market. All of the dials, characters, and options can get a bit confusing if you don’t have experience using a multi-meter. In this episode, I talk about how to use a commonly used tester, the Fluke T5-600.
Technically the fluke T5 is not a “multi-meter.” Fluke’s website lists it as a “tester,” while their Multimeter section shows only digital multimeters with no separate jaw-type ammeter. However, a multi-meter is simply a “multi-use meter” - something that can test several different electrical units of measure. The T5 measures voltage, amperage, resistance, and continuity. There are other multi-meters out there that have extra functions but the T5 is for the basic 4 that most electricians will use every day. So how do we use it?
VOLTAGE -
What you’re doing when you’re testing for voltage is testing the difference of potential between two points. “Voltage” is a difference of potential between two points in an electrical system. It is not a reading of one conductor, it's reading a difference between two. It can even be a difference between one wire and a piece of metal that’s bonded to earth. But keep in mind that you’re trying to get a value that shows “the difference in potential” between TWO things.
Flip the dial of the T5 to the “V” and take the leads out of the slide-in slots on the back. Ensure that you’re wearing proper PPE such as insulated “hot-gloves,” and a flash suit if you’re working in an electrical panel. Take one lead and touch it to a known hot conductor or terminal. Take the other lead and touch it to that same conductor or terminal. Notice you get a reading of 0v. This is because this conductor is at the same potential as itself. To get a voltage reading you have to test between two different objects.
AMPERAGE -
How to use the amperage setting - Flip the dial to the “A” (Amperes). Line your wire up with the two lines inside of the jaw of the ammeter. Only measure one wire at a time. This tester will give you readings up to 100 amps, so for anything more than that you’ll need a larger tester. This makes sense since the max size wire you can fit in the ammeter is 1/0 THHN. If you have larger wires than 1/0 THHN then you’ll need to get your hands on a clamp-on ammeter.
RESISTANCE -
Flip the dial to the Ohm (Omega) symbol. For this you want to test on a dead circuit so make sure the power is shut off. To test a conductor’s resistance you will need to have access to the beginning and the end of the conductor. Put one lead on the beginning of your conductor and one lead and the end of your conductor. This meter will display how many ohms of resistance there is between the leads. When there is low resistance you will hear a loud toning noise. When you try testing a really high resistance the tester will stop emmiting a tone, and will instead just display values. This meter is only good for up to 1,000 ohms. Anything more than 1,000 ohms should really be tested with a megger (megohmmeter)

    Please note: Resistance/continuity setting is only for non-live circuits. You can damage your meter or cause injury if you test resistance on a live circuit.

    You should do a video on how to find a neutral in a control circuit. I know you won't ever see relays out in the field, but the use of control relays is a big part of any industrial setting. I've noticed that some people will get confused when a relay is being controlled by a neutral and not a hot. Relay power terminals do not have polarity, so it doesn't matter which wire you put on the 7 or 2 to energize the coil.

    One bad thing about using the continuity setting to check a wire is that it will show complete continuity on a multi strand wire even if all but one strand are broken which is bad because that one intact strand will lead to thinking the wire is good and can handle the current when in most cases it will not handle the current which may lead to that wire over heating and causing a fire. Same thing applies when using the resistance setting.

    I cant imagine a scenario where the situation you described is even possible to cause a fire without a breaker tripping or whatever was connected to the circuit stop functioning. even if there is somehow only one strand connected inside of the insulation, it would evaporate itself under load and the circuit would break way faster than it would take to create any meaningful heat source to anything else

    You should always take safety measures but in order to get a reading for voltage or amperage the power must be on. ONLY when you are checking for (resistance) that circuit must be off. I’ve seen guys blow meters up with a back feed of electricity coming back to the meter when checking for resistance. Be safe and if you are not sure call a professional. Your life is worth more than whatever a service call may be. Hope that helped you
