Multimeter Guide & FAQ

How to use a digital multimeter?

First thing to know before seeing ways to use meters is about part of meter itself. First is display where users are able to see 4 digits of measurement result. Some of them come with illuminated displays to get better view in low light condition. The second part is selection know that gives chances for users to set meters to read many kinds of measurements like current voltage, resistance, and others. Last part is ports. Two probes are going to be plugged into two ports. After knowing them, let’s just see how to measure with multi-meters. Try AA battery to measure.

1. Plug black probe one into COM and then redone into MAV. Set DC with 2V
2. After that, squeeze probes against + and – terminals with a little pressure
3. If the battery used is fresh, voltage should be 1,5V
4. When you are going to measure DC voltage, set the knob where the V has line that is straight.

Second try is about to measure resistance. Pick resistor randomly, and then set into 20k ohm. Make sure to hold probes against legs of resistors with same pressure as you press key on keyboard. It’ll read one of three things.

What to look for when buying or comparing digital multi-meter

When you are looking for best multi-meter, it actually depends on what you need them for whether you will use it for measuring temperatures, or others. Some goes with different price and different features, but there are several main points in choosing best meters

• Accuracy is the primary thing in choosing this. Standard one is wise enough to buy. It has range from DMM one to analog that has had accuracy 2,5% or lower than that
• Input impedance where it becomes the second consideration. If you go to DMM, so choose ones that have 10 Mohm or 1 Mohm for AC.
• Features of measurements are also coming for good consideration as they are important to know worth of certain multi-meter. Do they measure AC, DC, resistance, diode check, temperature, humidity or others? It all depends on your need
• Switch range way is not too special in basic needs, but it can be good consideration to take account. Go with automatic will be nice because this feature can be safe and useful for knowing high
• Range measurement is also important due to its vital function. The wider range will be better.

Should we go Digital or Analog? 

When we are asked whether you should go for analog or Digital, you should ask yourself first. Both analog and digital are legit, and it all depends on your needs. Analog one is usually called as VOMs, and then digital one is DMMs. To know the difference, here are our brief explanations about both types. VOMs are actually good because the way reading it is much easier than DMMs. It also gives ease to see changing value in multi-meter. In DMMs, it is quite different because it has graph that tries to do a similar reading out as well as in VOM. In this modern era, it seems that everyone now goes to digital multi-meter because VOMs have several issues like lower input impedance. DMM has good impedance. Although it has no big effect when it has been doing in many circuits but sometimes it could be thing to watch out. Another reason why DMM is better than other is because additional features that VOMs don’t have. In time when technology has been growing so fast, finding best VOMs is hard because DMM manufacturers are bombing the product in the market. The conclusion is that DMM is better to get more features and ease.

What recommended features should be taken?

So it’s been a while after giving brief explanation why people should go for DMMs. It is quite a hard question as many people still believe that VOMs do better than DMMs but to be true, it talks about feature when it has come to consider before buying best multi-meter or picking best digital multi-meter. Basic things in having this meter are about accuracy, functionality, build quality, and calibration. Poor accuracy actually is not really a thing, but when it has become to make it better in term of working, accuracy gives better help. Regular calibration is able to give better accuracy. Third thing is functionality where it surely visits on additional feature on measurements like measuring diode, capacitance, temperature, and frequency. The last matter is about build quality. It’s all about safety issue. Fit and finish are a thing on high-quality meter. Unit should be guaranteed on durability. It’s quite hard when budget has become a matter of choosing, but it ignores some recommended features that have been the basic thing in choosing meter. That is why build quality is able to prove after years when it’s judged as most expensive one. You’ll get what you pay. 

How about Bench Meter? 

What is a digital multi-meter used for? It’s a simple question when some people have already VOMs or analog meter. Handheld multi-meters are various but when it’s been advanced, and you’re not satisfied with performance of DMMs, some improved or refined tool is bench meters where it used to be used by professional engineers. Some of them prefer to use bench meter than VOMs or DMMs. High-end handheld multi-meters offer superior features. It’s the best option after DMM. To choose more advanced tool in measurement, don’t ever take cheap offer. In electronic or even serious tool like meter, don’t take seriously on offer less than $800. Money talks a lot about quality. Choosing bench meters that come less than $1000, it’s too risky. Most recommended handheld meters come from Fluke multi-meter or Agilent. Some people may ask why regular DMM is not enough. This is all about refinement and better result of measurement to get best fixation in your car or electronics. Once we know more about details like frequency, temperature or others, it’s more delightful. Some engineers agree that buying high-quality one is far better and saving more budgets as it offers high durability and good functionality. 

How much safety should we consider?

Almost all people or even engineers never want to take any risk in refining something especially in electronic stuff. When it’s come to test circuits that have more than 30 voltages, it needs to think a lot about the best multi-meter that has been designed with high safety. It starts from unit. Does it stand years and it’s far from corrosive or impacted danger? In choosing best meters, looking for and thinking measurement rating is indeed good and giving good impact on being picky in accuracy and result but before thinking about rating, CAT III or others, you’d better go to see design of meters you’ll choose. You have to see how the internal shields are and do it have internal blast? Do they have wide flanges preventing fingers from slipping? It actually can be seen on probe to see how much width of flanges. All of parts in meter have sensitive effect on every single thing you do with meters. Everything that runs in electronic and AC/DC will always have risks but with high safety and high standard of safety designed in handheld multi-meter is going to prevent any worst risk happened when running work about checking voltage, frequency and others.

Important Point to Consider on Using Digital Multimeter

• Using smallest scale: To measure resistance, use smallest scale to do more accurate readings. For example, measure the 100 Ohm Resistor, use a scale of X1.
• Concern on Polarity: To measure DC voltage, note polarity, not to reverse. Adjust large scale of measurement with measured voltage. For Example on measuring voltage of 15V, 30V range use, don’t use 12-volt range, because the needle will hit the limits of its measure.
• Polarity allowed: To measure the AC voltage, polarity doesn’t matter. Adjust large scale of measurement with measured voltage. Example, for measuring voltage of 220V, 300V range use, don’t use 120-volt range, because needle will hit the limits of its measure.
• Measuring limit, concern on polarity: To measure DC current, note polarity and measuring limits. Be careful when measuring flow, because at this time hold on table in multi-meter be very small. Procedural errors can result in broken or burned at least multi-meter fuses broken.
• Consider measuring point: Remember that voltmeter in parallel with measuring point so that ability to hold voltage is infinite while the ammeter in series with measuring point so that it’ll be zero. Always be careful in making measurements, estimate acquisition of voltage or flow/influx before measuring it.

HVAC vs. Electrician? The Role of Multimeter in their perspectives

Related with using multimeter discussion, you must be able to distinguish between those who’ll use multimeters. Usually, there are two professions that require person to use digital multimeters as main weapon. They are HVAC technician & electrician. Although sounds similar because both are related to building construction process, but there is quite a fundamental difference distinguishes the two professions into single opposite polar.

Air System Administration or more commonly known as HVAC (Heating, Ventilating & Air Conditioning), plays an important role in a building. This is due to provides protection for surrounding environment, protecting families from dangers coming from air. HVAC is a reflection of implementation of GMP and one of critical supporting infrastructure that makes role of home or building important. Air System management is system that arranges / manage environment through controlling temperature, relative humidity, air movement and direction of air quality, including controlling and disposal of contaminant particles on air (such as ‘vapors’ and ‘fumes’). An HVAC technician requires a multimeter to investigate pressure of air emerging from static electricity. Usually, the shock waves such as static electricity will spur explosion when positioned close to a gas leak. Therefore, HVAC technicians have to carry the device all times.

In contrast to electrician, though they should bring multi-meter or any other measuring device anytime, but function of tool instrumental in installation of electricity may be different. Thus, electrician can determine safety of electrical installation using multitester. Prevention of surge should be primary consideration in work points. Multimeter able to provide accurate information for preventing short circuit. Comparing electrician vs. HVAC in connection with digital multimeters usage not directly related to functions and benefits of this tool. But for engineers, it becomes crucial given directly related to their work. 

How to Use Analog Multimeter

For technicians, using analog multimeters is probably already familiar. But for amateurs, ordinary people or those who rarely associated with such tools, they’ll find difficulty in using. Especially when come to reading needle on panel display tool which shows some very strange number, code, and value for you. Start working with both of them in a short time learning, see our explanation of how to use analog multimeters:

• The first step in using a multimeter course, we should be familiar with these tools and learn function to measure ohm (resistance), volts (the voltage) and ampere (current). Note the stylus on multimeter; it  shows measurement scale, and above it, there is usually some sort of glassy surface used to minimize error readings.
• Note the switch or knob on multimeter, This is to change function between volts, ohms, and amperes, and change scale (x1, x10, etc.) on multimeter. Thus becomes very important before using a multimeter, (should be calibrated and set correctly) to avoid damage on multimeter and usage errors in reading final results. Some multimeters have the switch “Off” so when not in use make sure the knob multimeter set to Off.
• Find a hole on multimeter, usually some multimeters have few holes, which later included jack cable to probe or multimeter terminals, this hole used for several different purposes. One hole is usually labeled words “COM” or (-), which means commonly that hole be used to probe cable or terminal in black. And almost every measurement used.
• Other sockets are usually given a “V” or (+), this is usually later used in measurement of voltage and resistance. Symbol (+) and (-) indicates polarity of probe or voltage. Thus red cable input socket on the hole marked “V” or (+) and black on the hole marked “COM”.
• Check whether the battery in multimeter attached or not, and in a good condition, because battery will be used when measuring resistance, so to measure resistance, good to use good condition / full indicated battery on multimeter, and ensure getting fuse on device, in which fuse used to protect component or multimeter when measuring currents or voltages in case the multimeter capabilities over limitation, so if fitting is used to move needle on multimeter cannot be used means battery is damaged or begins to run out. Replace batteries immediately.

It could be applied for almost all technician work. You just have to try in different activities including research continuity, battery testing, frequency and other work. 

How To Use A Multimeter To Test Continuity

Using multitester for measuring continuity or track is quite difficult. Especially for amateur, they must understand the difference between voltage, amperage, and electrical lines. Get all three in different roles would require us to learn in short time. Actually, there are easy steps to resolve issue and do not spend much time.

• Select Scale Buzzer, Sound icon or LED indicates scale. If red tester and black wires attached directly, then multitester will sound a beep signal means the line doesn’t have a problem. Values ​​without resistance (<50 Ohm) is the first indicator that should be recognized by user.
• Select object measurement. Suppose technician will measure ON Power lines on electrical circuit, you should find whether electrical lines on On-Off switches have a barrier or not. Attach one wire; you’re free to use any cable used on switches feet, other on IC UEM P7 diode feet or nearby capacitor. The indicating sound of “beep” indicates that the line functioning perfectly. The absence of “beep” signal leads technician to check electrical lines again. Whether both already functioning optimally or not.

When finished with searching issues, your work will be completed quickly.
