This meter has an alarm to let me know if I'm attempting to measure something and havey leads plugged into the wrong ports. That is, if you make a selection on the dial, and the leads are in the wrong position, a very audible alarm will sound off. It can be a minor annoyance if you know what you are doing and aren't going to improperly use your tool, but it is a nice safety feature for a novice user that also helps more comfortable users be mindful of their procedures. It's got a proper weight to it and doesn't feel delicate or cheap. CONCLUSION: It's priced decently, works accurately, and is (in my opinion) constructed for best use in work environments where regular component testing is necessary and in light duty construction.Construction quality is pretty decent. The only discrepancy in the product is with the display. The product images show a display screen with white characters on a black background. Actually, the screen is a typical display with backlighting as a selectable option. The characters are black on a standard LCD background - unlike that shown in the pictures. I was disappointed that the display is not the high contrast white on black as shown in the product photos. Despite that, the instrument is a bargain at the price.After thorough testing, it worked well. Very accurate and perfect for beginners. Cheap, very convenient and practical. Packing and instructions are helpful. Backlighting and retention are particularly useful. As far as price is concerned, this is an excellent deal. I know I haven't used it long, but it has a 18 months warranty and I think it will last longer. Solid feeling. Read quickly. The instructions are small and difficult to understand without a magnifying glass. Although the price is cheap, the quality is quite good. Clear display and reliable switch. The backlight is good. And it has an automatic shutdown feature, so the battery is very durableThe most impressive being the contactless high voltage scan function.

Placed next to the flashlight on the top of the reader, you can use it to test live wires without risking physical probing and electrocution. Has a backlight, durable probes (that you can store in the back. See pics), clear instructions, and different films (I assume to either tint the screen or the flashlight). A must have upgrade for anyone stuck with one of those cheap multimeters from Harbor Freight- you won't be disappointed!Contrast that to a more widely available four thousand count meter capable of displaying 0.000 to 3.999 volts before losing the millivolt digit. The meter is limited to less than millivolt accuracy at all but possibly very tiny voltages due to limitations in resistor precision, temperature drift, etc. It is these latter contributors to inaccuracy that labs pay many hundreds of dollars to Fluke, et al.The ability to select auto-ranging or to manually select ranges is nice, as is the non-contact voltage sensing capability, the frequency meter, and of course the true RMS cabability for measuring imperfectly reconstructed sine wave inverter output voltages, for example. The case is solidly covered with rubber, albeit not quite as soft as that found on high-priced meters. And I love the built-in probe storage clips. The probes themselves appear to be of decent quality, although an upgrade might be in order one day. All-in-all, a stunning value for the price says this old EE.There are few things I think can be improved: 1. The probe lead insertion is shallow and may easy to disconnected. 2. It beeps when you rotate the function selection dial. It is not really necessary since the dial itself generate loud enough click sound.

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. Hence the 'multi'-'meter' (multiple measurement) name.A multimeter is also great for some basic sanity checks and troubleshooting. Is your circuit not working. Does the switch work. Put a meter on it! The multimeter is your first defense when troubleshooting a system. In this tutorial we will cover measuring voltage, current, resistance and continuity. These concepts may be helpful with this tutorial:A few multimeters have illuminated displays for better viewing in low light situations. The COM probe is conventionally black but there is no difference between the red probe and black probe other than color. 10A is the special port used when measuring large currents (greater than 200mA).The probes have a banana type connector on the end that plugs into the multimeter. Any probe with a banana plug will work with this meter. This allows for different types of probes to be used. Here are a few of our favorites: Good for performing longer term tests where you don’t have to have to hold the probes in place while you manipulate a circuit. Almost all portable electronics use direct current ), not alternating current. Squeeze the probes with a little pressure against the positive and negative terminals of the AA battery. If you've got a fresh battery, you should see around 1.5V on the display (this battery is brand new, so its voltage is slightly higher than 1.5V). 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). If you're messing with AC, we recommend you get a non-contact tester rather than use a digital multimeter. The reading on the multimeter is simply negative. Nothing bad happens. The multimeter measures voltage in relation to the common probe.

To begin, let's make sure the circuit you are working on is powered up correctly. If your project should be at 5V but is less than 4.5V or greater than 5.5V, this would quickly give you an indication that something is wrong and you may need to check your power connections or the wiring of your circuit. Multimeters are generally not autoranging. You have to set the multimeter to a range that it can measure. For example, 2V measures voltages up to 2 volts, and 20V measures voltages up to 20 volts. So if you've measuring a 12V battery, use the 20V setting. 5V system? Use the 20V setting. If you set it incorrectly, you will probably see the meter screen change and then read '1'. One probe should contact a GND connection. One probe to the VCC or 5V connection. This practice is called nodal analysis, and it is a basic building block in circuit analysis. By measuring the voltage across the circuit we can see how much voltage each component requires. Let's measure the whole circuit first. 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. This is what is referred to as the voltage drop across the LED. If that doesn't make sense now, fear not. It will as you explore the world of electronics more. The important thing to take away is that different parts of a circuit can be measured to analyze the circuit as a whole. This is lower than the forward voltage stated in the datasheet on account of the circuit only having small amount of current running though it, but more on that in a bit. Nothing bad. The meter will simply display a 1. This is the meter trying to tell you that it is overloaded or out-of-range. Whatever you're trying to read is too much for that particular setting. Try changing the multimeter knob to a the next highest setting. If you're looking to measure a voltage less than 20V, you turn to the 20V setting. This will allow you to read from 2.

00 to 19.99. Most multimeters can measure AC (alternating current) systems, but AC circuits can be dangerous. A wall outlet with AC or 'main voltage' is the stuff that can zap you pretty good. VERY carefully respect AC. If you need to check to see if an outlet is 'on' then use a AC tester. Really the only times we've needed to measure AC are when we've got an outlet that is acting funny (is it really at 110V?), or if we're trying to control a heater (such as a hot plate ). Go slow and double check everything before you test an AC circuit. If you don't know what they mean, that's ok. There are plenty of online calculators that are easy to use. However, if you ever find yourself without internet access, a multimeter is very handy at measuring resistance. You will need to try a higher mode such as 200k.This means that the color codes may indicate 10,000 Ohms (10k?), but because of discrepancies in the manufacturing process a 10k.What happens? However, you'll notice that there is one more digit after the decimal point giving us a slightly higher resolution in our reading. What about the next lowest setting? Remember that measuring resistance is not perfect. Temperature can affect the reading a lot. Also, measuring resistance of a device while it is physically installed in a circuit can be very tricky. The surrounding components on a circuit board can greatly affect the reading. It's tricky because you have to measure current in series. Where voltage is measure by poking at VCC and GND (in parallel ), to measure current you have to physically interrupt the flow of current and put the meter in-line. To demonstrate this, we'll use the same circuit we used in the measuring voltage section. As mentioned, we'll need to physically interrupt the circuit to measure the current. Said another way, pull out the VCC wire going to the resistor, add a wire where that wire was connected, and then probe from the power pin on the power supply to the resistor.

When measuring current, it's often good to watch what your system does over time, for a few seconds or minutes. While you might want to stand there and hold the probes to the system, sometimes it's easier to free up your hands. These alligator clip probes can come in handy.Measuring current works the same as voltage and resistance -- you have to get the correct range. Set the multimeter to 200mA, and work from there. The current consumption for many breadboard projects is usually under 200mA. Make sure the red probe is plugged into the 200mA fused port. However, if you suspect that your circuit will be using close to or more than 200mA, switch your probe to the 10A side, just to be safe. Overloading the current can result in a blown fuse rather than just an overload display. More on that in a bit. The average reading was closer to 2.1mA. 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). On the multimeter display you should see the instantaneous current reading. All multimeters take readings over time and then give you the average, so expect the reading to fluctuate. In general, cheaper meters will average more harshly and respond more slowly, so take each reading with a grain of salt. In your head, take an average range such as 7 to 8mA under normal 5V conditions (not 7.48mA). What happens if we switch probes. It simply causes the current reading to become negative: It's common to grab a meter and begin to quickly measure the voltage between two pins. If you have left your meter in 'current' mode, you won't see the voltage on the display. Instead you'll see '0.000' indicating that there is no current between VCC and GND. So before you put the meter down for the night, remember to leave your meter in a friendly state.

Don't worry if you blow the fuse - we've done it dozens of times. We'll show you how to replace the fuse in a later section. This test helps insure that connections are made correctly between two points. This test also helps us detect if two points are connected that should not be. This feature allows us to test for conductivity of materials and to trace where electrical connections have been made or not made. It may vary among DMMs, but look for a diode symbol with propagation waves around it (like sound coming from a speaker). The multimeter should emit a tone (Note: Not all multimeters have a continuity setting, but most should). 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. You should hear a tone indicating that they are connected. Poke the probes from the VCC pin on a microcontroller to VCC on your power supply. It should emit a tone indicating that power is free to flow from the VCC pin to the micro. 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 your eyes can't see it, the multimeter is usually a great second testing resource. Here are the steps to take: 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. If there is continuity (if you hear a beep), then you've got a short somewhere. With continuity, check that VCC and GND are correctly wired to the pins on the microcontroller and other devices. The system may be powering up, but the individual ICs may be wired wrong. This is a good sanity check before powering up a prototype to make sure there is not a short on the power system. But don't be surprised if you hear a short 'beep!' when probing. This is because there is often significant amounts of capacitance on the power system.

The multimeter is looking for very low resistance to see if two points are connected. Capacitors will act like a short for a split second until they fill up with energy, and then act like an open connection. Therefore, you will hear a short beep and then nothing. That's ok, it's just the caps charging up. As the current rushes through the multimeter, the internal fuse will heat up and then burn out as 200mA flows through it. It will happen in a split second and without any real audible or physical indication that something is wrong. If you try to measure the current with a blown fuse, you'll probably notice that the meter reads '0.00' and that the system doesn't turn on like it should when you attach the multimeter. This is because the internal fuse is broken and acts as a broken wire or open.The SparkFun DMM is pretty easy to pull apart. Start by removing the battery plate and the battery. You will need to slide the face sideways with a little force to disengage these hooks. Now you can see inside the multimeter! In other words, replace the 200mA fuse with a 200mA fuse. The placement of the fuses may not match the placement of the probe ports. Read the metal cap on either end of the fuse to double check which is which. You will damage and possibly ruin your multimeter if you accidentally push 5A through the 200mA port. Do you see the two places to put the red probe on the front of the multimeter? 10A on the left and mAV.But if you use the 10A port to measure current, you run a much lower risk of blowing the fuse. The trade-off is sensitivity. As we talked about above, by using the 10A port and knob setting, you will only be able to read down to 0.01A or 10mA. Most of my systems use more than 10mA so the 10A setting and port works well enough. 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.

If you really need to see how the IC uses current or voltage over time, use an Agilent or other high quality bench unit. These units have higher precision and offer a wide range of fancy functions (some include Tetris !). Bunnie Huang, hardware designer behind Chumby, uses high-precision current readings to trouble shoot boards during the final testing procedures of a Chumby. 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). By pinpointing what may be potentially wrong, the rework and repair of boards is made much easier. Every other feature is just icing on the cake. Auto-ranging can be very helpful if you know how to use it. Generally speaking, autoranging multimeters are higher quality and generally have more features. So if someone gives you a multimeter with auto-range, put it to use. Just know how to get it into manual mode. A circuit's voltage or current can fluctuate quite quickly. With some of the systems, the current or voltage is so sporadic that the auto-range can't keep up sensibly. 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. A soft knob is usually indicative of a shoddy meter. Over time the leads will tend to break down at the flex point. We've seen wires come completely out of probes - and it's always at the moment you need the probes to work. If you do break a probe, they are reasonably cheap to replace. This is a feature that can benefit beginners and advanced users alike, as it's easy to forget to turn the meter off at 2AM. The SparkFun digital multimeter doesn't have this feature, but luckily the meter is very low-power. We've left the multimeter for two days straight before the 9V battery began to get low.

That said, don't forget to turn your meter off! Feel free to start using it to answer many questions. I believe my LED is getting 20mA, is it really. How much voltage does a lemon have. Is a glass of water conductive. Can I use aluminum foil to replace these wires. A digital multimeter will answer these and many more questions about electronics.

Some have lasted many years, some failed very quickly. Dependability will remain to be seen on this one, but aside from that long term review, this is the best multimeter I have ever purchased.

It is a great price and value for all the features it offers. It has a a huge, easy to read display, and has a backlit button. A huge plus. Also, it has a decently strong magnet on the back so i can hang it on a metal surface while working. It comes with various means to read devices, like standard leads, butterfly clips, and more. It is well built, and feels very sturdy.stronger than some more expensive ones I have purchased. There is tons of readings here, including AC and DC voltage, temperature, resistance, amperage, and more. You can see the full list above. Overall, so far, I am very happy with the product. It lost one star as the ad states it comes with a protective cover, and this was not included. To be fair, I have not contacted them about it, as it does not make or break the device purchase, but it did not include it. Also, as recommendations (but not affecting my score in any way), 1. wish the magnet was a little bit stronger. It sticks well, but it does feel like it can be pulled off easily. Hasn't happened yet, but that is because I am cautious. Also, it would be good if the back light could be turned off and on, as opposed to about 15 seconds. 15 seconds is decent amount of time, but if you are testing multiple circuits, it would be great to turn it on and off as needed. But these are just recommendations on the existing design. Love it otherwise!The reason it doesn't deserve 5 stars is because of the test leads it comes with. They have tiny metal tips which make it impossible to test some components, such as sticking a lead inside a jack of some kind. It also did not come with alligator clips, which was disappointing. The unit itself is great, but the leads really make it frustrating to use.
