It's small, compact, and still easily readable and usable. This DMM kit is awful. If you really need to see how the IC uses current or voltage over time, use an Agilent or other high quality bench unit. The input jacks are proper metal cylinders and soldered all the way around into the PCB. Does anyone know the overall dimensions of this product? If there is continuity (if you hear a beep), then you've... Power the system down. In other words, replace the 200mA fuse with a 200mA fuse. If it does not emit a tone, then you can begin to follow the route that copper trace takes and tell if there are breaks in the line, wire, breadboard, or PCB. If you're trying to measure very low power (micro or nano amps) the 200mA port with the 2mA, 200uA, or 20uA could be what you need. We can test different parts of the circuit as well. Wow, that was neat. With some force (imagine poking a fork into a piece of cooked meat), push the probes onto two exposed pieces of metal. Even bought an identical replacement after I dropped a bolt cutter on my first one (an obviously completely unrelated bit of advice: don't carry bolt cutters in poorly secured bicycle panniers.). No Sparkfun red? The important thing to take away is that different parts of a circuit can be measured to analyze the circuit as a whole. When a system is not working, continuity is one more thing to help troubleshoot the system. Thank you for your continued support. How much voltage is there on the ‘-’ of the battery compared to our new zero? you will be probing for continuity between ground and the VCC rail. it seems to help if i push the metal rods deeper into the housing but needless to say i cant always do this when trying to measure resistors or other components. The meter will simply display a 1. The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. Nothing bad happens! We'll show you how to replace the fuse in a later section. The dial has 20uA. Just know how to get it into manual mode. Fluke just issued a response to the impounding of multimeters headed for market in the United States. Text, image, video.

You can use the multimeter to … Then hold the probes against the resistor legs with the same amount of pressure you when pressing a key on a keyboard. I actually like the idea of a red version, much more Sparkfun-y. $17.51 USD The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. If your eyes can't see it, the multimeter is usually a great second testing resource. How much voltage does a lemon have? Realize that the multimeter is acting as a piece of wire -- you've now completed the circuit, and the circuit will power on. Whatever you're trying to read is too much for that particular setting. I received this meter, and it seems to be working fine, but the first time I took it off the bench I hear something rattling around inside. We welcome your comments and suggestions below. This one is from SparkFun and is supporting one of the best small tech company's ever with the best tech support/customer support that answers silly questions. Therefore, you will hear a short beep and then nothing. This basic multimeter measures DC & AC voltage, DC current, resistance, continuity, & test diodes. I can totally vouch for this model. to each his own. Because this resistor (a 1KΩ) is less than 2KΩ, it still shows up on the display. We generally steer clear of scary forests and situations that require us to test stuff in the middle of the night, but some people may want or need a dark-friendly multimeter. It will as you explore the world of electronics more. Mine came missing the screw for the battery compartment. The multimeter measures voltage in relation to the common probe. Don't worry, this happens all the time, and it costs about $1 to fix. Also, when I click the "Multimeter tutorial" link it does not work. The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. What happens? Regular price $35 29 $35.29. no. 'Cause I'm a rebel. If we switch the probes, we define ‘+’ as the common or zero point. Let's measure the whole circuit first. These units have higher precision and offer a wide range of fancy functions (some include Tetris!). Compare Product. Mon-Fri, 9am to 12pm and A couple of things I found a bit irritating: Most probes have fully shrouded plugs; these have half-shrouded plugs. The SparkFun Digital Multimeter is the multimeter of choice for those looking to combine quality and low cost. (Also, the probes are shrouded for a reason!). The meter will read one of three things, 0.00, 1, or the actual resistor value. Please see all COVID-19 updates here as some shipments may be delayed due to CDC safety and staffing guidelines. they do seem to work better, however as the member above me pointed out they do not seem to fit correctly in the actual multimeter. verified purchaser. I'm so gonna paint my yellow, straight up, perfect match fluke yellow... just because I can. Here are a few multimeters and kits with multimeters to suit the needs of beginners and experienced hobbyists alike. Auto-off is a great feature that is rarely seen on cheaper multimeters. verified purchaser. SparkFun Digital Multimeter. As mentioned, we'll need to physically interrupt the circuit to measure the current. For these pictures, we cheated and used alligator clips. 1pm to 5pm U.S. Mountain Time: So... how do I use a multimeter? Add to Wishlist. I THINK THERE IS NO EXCUSE FOR LEAVING OUT A VERY SIMPLE CMOS CIRCUIT THAT TURNS OFF A BATTERY POWERED DEVICE WHEN NOT IN USE. USE with caution! Let's drop the meter down to the next lowest setting, 2KΩ. Here are the steps to take: Continuity and large capacitors: During normal troubleshooting. A digital multimeter will answer these and many more questions about electronics. The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. If there is continuity (if you hear a beep), then you've got a short somewhere. INSMM-009141. That's ok, it's just the caps charging up. im not sure if the included leads are supposed to have the metal rods with the points come out of the plastic housing but i suspect that is why i hardly get a reading. We started sourcing a really great high-quality $15 multimeter back in 2008. However, if you are looking for solutions to technical questions please see our Technical Assistance page. Will contact support and try again, maybe the second one will work. Add to Wish List. The surrounding components on a circuit board can greatly affect the reading. Garbage. SparkFun Multimeter Kit The SparkFun Electronics digital meter (KIT-09573) is a kit that is available for $19.95, not including shipping. Lift the face of the multimeter slightly. But it works and for the price it's great, about 6 years ago Every other feature is just icing on the cake. This is a good basic multimeter for a fair price. I'm one of the lucky guys that has the Sparkfun grey/yellow here: Anyways, I think it is totally ridiculous regarding "trade dress" on colors. The soldering is excellent, there's decent (but not excellent) input protection, a loud continuity buzzer, and all the basic features a student or basic hobbyist would need. A back-lit LCD is fancy, but when was the last time you measured your circuit in the dark? Learn the basics of using a multimeter to measure continuity, voltage, resistance and current. Plug everything in and works right out of the box. I feel like i'm on some alien world surrounded by morons. The first thing we'll need is an extra piece of wire. verified purchaser. Both are 5x20mm sized. You may need to reference datasheets, schematics, and know the ins and outs of electronics. 10A is the special port used when measuring large currents (greater than 200mA). If you have money to spare, I'd recommend the other, self-adjusting DMM, about 6 years ago This is important because as time goes on the LED, microcontroller, sensor, or whatever device being measured may change its power consumption (such as turning on an LED can resulting in a 20mA increase for a second, then decrease for a second when it turns off). Harbor Freight: Still only $6.99 w/ backlight! Likewise with multimeters. If not why do you sell it? This multimeter should provoke no strong feelings one way or the other, we know this because our guts say "maybe.". about 3 years ago If that doesn't make sense now, fear not. AC voltage (like what comes out of the wall) can be dangerous, so we rarely need to use the AC voltage setting (the V with a wavy line next to it). A soft knob is usually indicative of a shoddy meter. It takes a second or two before it'll give you a reading. ha, I think you guys are clever enough to figure out how to do that without a kit. Does the switch work? One for the 20uA to 200mA range and the other is for the 10A range. verified purchaser. GOOD value for this price but, Two probes are plugged into two of the ports on the front of the unit. Digital Multimeter - Basic - TOL-12966 - SparkFun Electronics The trade-off is sensitivity. Make sure to replace the correct fuse with the correct type. The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. With both probes red as well !!!! perhaps i need to buy better leads but for now i have to say its really not even worth the $15 i spent on it. You will need to try a higher mode such as 200kΩ mode or 2MΩ (megaohm) mode. in fact, I think I'll pick up a second today. If you're looking for a good value in a multi-meter you can't go wrong. replied on February 13, 2015: I'm sorry to hear that you had problems. Power the system down. It's relatively easy to make it miss a quick tap of the probes. Almost all portable electronics use direct current), not alternating current. This is because the internal fuse is broken and acts as a broken wire or open. However, if you ever find yourself without internet access, a multimeter is very handy at measuring resistance. by Sn0MaN If the 5V system is running at 4.2V check your regulator carefully, it could be very hot indicating the system is pulling too much current. This is the meter trying to tell you that it is overloaded or out-of-range. All multimeters take readings over time and then give you the average, so expect the reading to fluctuate. images are CC BY 2.0, The digital multimeter (DMM) is an essential tool in every electronic enthusiasts arsenal. Thanks. This thing might get a little scratched up, but it doesn't seem easily damageable. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes. When you turn it on, it just works. We've played with a lot of cheap-o DMMs and found that this unit's function selector has a great, solid, clicking feel to it. I'd love to see Sparkfun carry a more advanced meter. Not a whole lot changed. Over time the leads will tend to break down at the flex point. The plugs make a solid connection and don't feel like they are letting off of their firm hold even after trying to abuse it a bit. This is what the product images indicate. This allows you to troubleshoot circuits with small SMD p…. Note that almost all multimeters have the same sized jacks (they're called "banana plugs") so if you're in a pinch, you can use your friend's probes. by BerenV The youtube video included at the bottom is not accessible and it says that it's private. This tutorial will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people's electronic designs, and even test a battery. mAVΩ is the port that the red probe is conventionally plugged in to. Does anyone know where it belongs? While you might want to stand there and hold the probes to the system, sometimes it's easier to free up your hands. i cant even measure a 330 ohm resistor and find out what value it is because the connection seems to be so poor. Regular price $24 29 $24.29. Filter by. The reading on the multimeter is simply negative. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes. I had forgotten about that until this showed up in the New Products Post this week. Regular price $12 99 $12.99. Not the greatest meter ever made, but also not the most expensive meter ever made. On a breadboard that is not powered, use the probes to poke at two separate ground pins. about 6 years ago I didn't even need a multimeter at the time, but I bought it anyway, so I could have a collector's item. This test also helps us detect if two points are connected that should not be. One probe should contact a GND connection. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes.

With sub $50 digital multimeters, the measurements you are likely to take are just trouble shooting readings, not scientific experimental results. by raster Remember that measuring resistance is not perfect. Just. To begin, let's make sure the circuit you are working on is powered up correctly. When measuring current, it's often good to watch what your system does over time, for a few seconds or minutes. Great product, not much to say about it besides it works exactly as advertised and has a great durability, plus easy to use. By measuring the voltage across the circuit we can see how much voltage each component requires. Gently lift up on the fuse, and it will pop out. (We don't stock) We've played with a lot of cheap-o DMMs and found that this unit's function selector has a great, solid, clicking feel to it. This practice is called nodal analysis, and it is a basic building block in circuit analysis. This is for all those starving students that need to buy their first good, low-cost multimeter. Great value, slick design. Good enough for most tasks. about 6 years ago By looking at the current consumption of different boards that have failed (for example a given failed board uses 210mA over the normal), he could identify what was wrong with the board (when the RAM fails, it generally uses 210mA over normal). It is an autoranging meter that focuses on a few basic measurements: DC voltage, DC current, resistance, and continuity (buzzer). Generally speaking, autoranging multimeters are higher quality and generally have more features. Just on note of warning about this "cheap" multimeter. Try changing the multimeter knob to a the next highest setting. verified purchaser, If you don't want to spend a lot of money, go with this. For the price, it's quite an excellent little meter and definitely a good pick for a student's first meter. As a rule of thumb, it's rare to see a resistor less than 1 Ohm. -1.5V! We've left the multimeter for two days straight before the 9V battery began to get low. The development and breakout boards that are produced by SparkFun are usually tested on a pogobed and inspected by a technician for quality control before they are packaged and sent out. This shows that a very small amount of current is allowed to flow without resistance (or at least a very very small resistance) between probes. The current consumption for many breadboard projects is usually under 200mA. $19.95. The multimeter should emit a tone (Note: Not all multimeters have a continuity setting, but most should). about 4 years ago If you're measuring DC voltage (such as a battery or a sensor hooked up to an Arduino) you want to set the knob where the V has a straight line. The SparkFun Digital Multimeter, however, is not your average multimeter, it features a loud continuity sound, current/voltage sense, and quality probes. If Chevy were to only manufacture blue cars from this day forward - does that mean that Ford or GMC cannot make a blue car??? With this version we've done away with the bright flashy colors that can get us into trouble and gone with a nice, neutral gray. verified purchaser. You will need to slide the face sideways with a little force to disengage these hooks. Bunnie Huang, hardware designer behind Chumby, uses high-precision current readings to trouble shoot boards during the final testing procedures of a Chumby. This is because there is often significant amounts of capacitance on the power system. Start by removing the battery plate and the battery. Now, since 1kΩ is greater than 200Ω, we've maxed out the meter, and it is telling you that it is overloaded and that you need to try a higher value setting. The SparkFun DMM is pretty easy to pull apart. This meter has really impressive overall feel for being so low-cost. by CompuCat Power the system down and check continuity between VCC and GND. Overloading the current can result in a blown fuse rather than just an overload display. One probe to the VCC or 5V connection. Measuring from where the voltage is going in to the resistor and then where ground is on the LED, we should see the full voltage of the circuit, expected to be around 5V. Top reviews. Do you see the two places to put the red probe on the front of the multimeter?
