What is a Digital Multimeter?

It is an electronic instrument used to measure various functions in a unit. It is also called as ohmmeter, voltmeter or volt-ohm meter. In general, the standard multimeter is used to measure the estimations of voltage, amperes and ohms. While this digital multimeter will perform some extra estimations, which incorporate recurrence, capacitance, temperature, congruity and so on with its advanced and rationale innovation. This advanced multimeter is much speedier, more effective and work with exactness or accuracy when compared with a normal multimeter.

What can be measured with this digital multimeter?

The standard multimeter is used to measure quantities like resistance in ohms, voltage in volts (direct & alternate) and current in amperes (direct & alternate). Whereas the digital multimeter is used to measure other parameters like capacitance, inductance, conductance, temperature, frequency, recurrence, inductance, continuity, etc.

Where this Digital Multimeter is used?

Generally, multimeter is used in repairing, testing and installing the electrical devices like batteries, household wiring and electric motors & power supplies. Here are some areas of application for this digital multimeter.

  • Automotive testing
  • Construction area
  • Electronics and Electrical Testing Quantities
  • Electricians Hand Tool
  • Installation and Testing Sectors in Manufacturing Industry
  • Repairing each & every Electronic Components.

How To Choose Digital Multimeter?

Due to huge demand for testing equipment, there are so many brands coming into the market. This will make us hard to pick the best digital multimeter for your purpose. Even though, if you won’t need all these functions but it’s a better idea to get a digital multimeter for future purpose. Here are the factors, which you need to check while purchasing the digital multimeter.

1. Manual Range VS Auto Range

When comparing the auto range and manual range, the auto range multimeter is much easier to use. In case, if you’re a beginner or budget freak then prefer to choose manual range meter.

  • Auto-Range Meter – Connect the device to this meter and select the desired parameter you want to measure and thereby turn it on to take reading/value on the screen. It selects its range by itself without adjusting manually.
  • Manual Range Meter – It is very annoying to use this manual meter while dealing with many components and values for a project. Here, you have to select the range by yourself by turning the nob each and every time.

Verdict:

Auto-range multimeter is best and easy to use rather than manual range. A few auto-range models come with a button to change the range and thereby you can use both manual & auto range modes.

2. Range Limits

We don’t know what parameters we require for your projects. So, one should know the range limits before purchasing the multimeter. For instance, if the meter won’t measure current in milli range then it won’t measure some sensor current values. Hence, the multimeter ranges will have to cover the demands of both the present & future projects.

Here are some recommended ranges:

  • Range for Resistance – 10 Ohm to 20 MOhm
  • Current Range – 10 uA to 10 A
  • Voltage Range – millivolt to 600V
  • In some cases, you have to deal with small capacitance (within milli range) with this meter to measure the reading.

3. Accuracy:

Accuracy is generally considered as the maximum permissible error limit while taking multi meter readings. Although, most of the multimeter, especially digital one will provide reading value accuracy but one has to check it properly before using it in the project.

For instance, a 0.5% DC volt accuracy with 4000 – 6000 counts are fine but greater than this value means the meter is not accurate or professional for taking reading. So, a multimeter should come with true RMS reading while measuring AC voltages and bandwidth above 50kHz.

4. Resolution (Display Counts)

The meter’s resolution or display counts will refer to the display of total digits, from minimum to maximum count. The best multimeter comes with higher display count. In general, the high-resolution handheld digital multimeter has a 2000-count with 4 ½-digit display, which enables the meter to display values from 0 to 19,999. Whereas 4000 count multimeter have 4 ¾-digit display that enable to display values from 0 to 39,999.

To bridge the gap between these two counts, you have to use 3 ¾ -digit displays or else 4000-count digital multimeter. Remember that most of the digital multimeters will leave the leading digit black when it is zero.

5. Continuity Response Time

Generally, it is stated that how quicker the response time is, the better will be your multimeter. It is handy and helpful while analyzing any circuit for open or short situations. In case, if your multimeter has slow response time, then it will be annoying and time consuming when analyzing the circuit.

6. Testing Transistor

Simply hook the positive lead of the multimeter to Emitter E of the transistor. In the same way, connect the negative lead meter to the base (B) of transistor. For testing PNP transistor, the meter will show some voltage drop between 0.45V to 0.9V. For an NPN transistor, one can find OL (over limit) while testing.

7. Temperature Measurement

Choose a digital multimeter with dual differential temperature function whenever you want recurrent thermocouple monitoring needs. This will allow the user to take readings of two temperatures at a time simultaneously.

8. Frequency Measurement:

In general, any circuit or device is designed to operate at either fixed or variable frequency. If it is operated at different frequency other than specified one then it may perform abnormally. For instance, if an AC motor is designed to operate at 60 Hz then it operates fast if the frequency is above 60 Hz and slower if the frequency is reduced. Also, changes in frequency range will result in proportional change in motor speed.

Here are some optional modes of measuring frequency in some digital multimeters.

  • Frequency Counter – It is used to measure the frequency of AC signals, while troubleshooting the electronic and electrical equipment.
  • Min Max Recording Mode – It allows to record the frequency measurements over a specific period of time. The same will be provided with current, resistance and voltage.
  • Auto-range Mode – The frequency measurement range will be selected automatically. In case, if the frequency of measuring voltage is out of the range then the digital multimeter won’t display accurate readings. So, always refer to the user manual to know about specific frequency measurement range.

9. Safety Features

Safety is always a first priority to any one who are dealing with electronic tools. For those who want to learn (beginner) how to measure the resistance values with a small 5V DC voltages, then choose a cheap multimeter where safety doesn’t matter much. But if you’re looking for a professional multimeter to measure higher values of DC or AC voltages then safety will be their first priority and has to follow some safety features, especially CAT safety measures.

Have a look on some of the safety measures to be followed while dealing with electronic tools.

  • Make sure to get the best quality multimeter from a trusted manufacturer, which is safe to use.
  • Always check all the fuses used by the meter. If you want to measure high or low current values then avoid purchasing a multimeter with glass fuse. Go for a multimeter with high quality cartridge fuses while measuring current to make it safe to use. If the meter won’t have fuses then it is not at all safe to use, as it burst and may catch fire if any mistake is made.
  • Secondly, look for the multimeter with CAT III rating, as it will ensure that the meter won’t blow in hands and thus you are safe, even if you short the mains accidently.
  • Then you have to choose quality probes, which are made mostly with silicone rubber to allow you to take reading safely without any getting any damage.
  • It is must to know which multimeter you should use while working with high voltages. Depending on the amount of current flow through conductor, one has to choose a device, which is a cross between a clamp meter and multimeter.

10. Input Resistance

It may be encountered by the user who are using the multimeter for the first time. So, let’s know about it. Input resistance is the resistance offered by a multimeter to a device, which is connecting across the probes. The higher the input resistance it offers, the better will be your multimeter. Generally, 1MOhm is considered as the best value of input resistance of multimeter.

11. Battery Time

One has to consider battery running time while using the multimeter regularly. It would be better to have a battery time of about 1000 hours. So, if you want to learn electronics by using multimeter then purchase a 1000 hours battery time (but not below) for best usage of digital multimeter.

12. Auto Hold Function

This is another essential feature to look when buying the multimeter. It allows you to take measurements easily. Connect the probes with both of your hands to let multimeter read the values. The readings on the meter will remain even if you’re not looking on the screen (OR) if you remove the probes. This feature will help you to work safely with AC mains, where one has to focus on the proper connections of probes and thereby not to touch any wire accidentally.

13. Versatility

Digital multimeter will offer versatility in both functionality and measurements rather than basic multimeter. For instance, the basic multimeter comes with features used to measure DC & AC current, resistance, voltages and capacitance, whereas the digital meter offers various other tests (like battery test, diode test, transistor test & continuity test) and perform functions (like analog bar graph, auto-range, true RMS or RS – 232 PC interface), which makes the digital one is much more useful than standard multimeter. So, always check the user manual of a device to select the best meter, as per your requirement.

14. Other Features

Here are some additional features mentioned, which you have to consider when selecting the digital multimeter.

  • Diode Measuring – One can easily find this feature on the multimeter either under diode or continuity function symbol. Most of the multimeters come with this function but the test voltage range is close 2V. The best meter will have test voltage range that is close to 4V to measure in every device.
  • Buzzer Function – It is useful for continuity testing. This will make the probes won’t slip while working head-down, where you don’t want to lift the head up to view the meter reading. So, a simple buzzer will provide all the indication of required continuity.
  • Capacitance Meter – This capacitance is used for testing capacitors but its range will be limited.
  • Probs – You should know how many different types of current, your multimeter should measure. This will decide whether the multimeter have one or more sets of probes used for different applications. While some of the multimeters are specially designed to measure by contact and a few others will grip the item when measuring. Some types of probes will include SMD tweezer, alligator, grabber/hook, temperature and socket.
  • Frequency Counter – Frequency is an essential parameter measured by meter, especially for RF applications like ham radio. However, its accuracy is not to be wonderful and sending the RF along with the probe leads is not a good option.
  • Back Light Feature – This feature will provide clear display and thereby shows clear reading even in low light areas.

15. Price

In general, digital multimeters comes in a wide price ranges that start from $10 – $3500, by depending on its bands and available features. Also, the DMM at higher price will be more durable and provides accurate results when compared with low priced DMM. For instance, workbench multimeter will be more expensive than handheld multimeter.

Make sure to check how frequently you are using this device and what features you need. Like if you’re an occasional user, then go with less priced device. If you plan to use the meter regularly then prefer to use a robust design at expensive price.

Advantages of Digital Multimeter:

Digital multimeters provide higher accuracy when compared with analog meter while taking measurement. The standard digital multimeters provide an accuracy of 0.5% DC voltage whereas the benchtop multimeter will provide 0.01%. Here are some advantages of digital multimeter. Let’s have a look on it to know what are those benefits.

  • The digital multimeter will provide more accurate reading rather than analog multimeters.
  • It reduces interpolation and reading errors.
  • The auto-polarity function will prevent some problems that arise from connecting the multimeter to circuit while testing with any wrong polarity.
  • Parallax errors are eliminated. In case, if the pointer of an analog meter is viewed from different angle then you will get different value. This is termed as parallax error. But a digital multimeter will display exact results by clearing this problem.
  • DMM will display results in no moving parts. This will make them free from wear and shock failures.
  • The reading speed is increased in this DMM why because it is easy to read the measurements.
  • The analog multimeters provide zero adjustment whereas in digital meter, the zero adjustment is not required.
  • With the arrival of integrated circuits, the cost, size and power requirements of the digital multimeter will be reduced.
  • Digital output is suitable for recording, processing and used to raise the range of computer-controlled applications.
  • You will get accuracy in digital readout on LCD display of DMM but one can make mistake while reading the scale in analog multimeter.
  • Digital meter is widely used to test capacitors, continuity, transistors and diodes. A few advanced models measure frequency as well.
  • DMM offers auto-range feature will help to select different measurement ranges to prevent damage to meter, in case, if the user selected any wrong range.
  • The less meter loading effects will be caused on the circuits while it is tested by using DMM.
  • A few high-end models of DMM comes with microprocessors, which help to store the reading for future reference.
  • The digital one comes with a high input impedance and the portable one will allow you to carry it easily to anywhere.

Disadvantages of Digital Multimeters:

Just like so many advantages, a digital multimeter have some disadvantages, which are mentioned below.

  • It is recorded as an error, if it finds any fluctuations or transients.
  • The LCD display depends on any external power source or battery. In case, if the battery is low then the display will be dim and thus it makes some difficult to read.
  • DMM face voltage limitations. In case, if the voltage exceeds the maximum range then the multimeter will get damaged.
  • DMM is not suitable to adjust the tuning circuits or peak tunable responses.
  • It is expensive due to high manufacturing cost.

Frequently Asked Questions?

1.What are the types of Multimeter?

In general, there are two types of multimeters – analog and digital. Analog multimeter provides a continuous deflection of pointer that represent to measure the value of power quantity. It also measures the current, resistance, duty cycle, voltage, transistors and capacitors. The resistance of these analog multimeters will depend on the chosen range and sensitivity.
Whereas the electronic/digital multimeter comes with a digital decimal LCD display. For measuring varying voltage, a bar circuit will hold the current sample before measuring or displaying a new sample. The analog meter is rarely used in these days and sensitive than digital meter. DMM provide accurate results but while dealing with circuits having highly sensitive measurements, analog meter will provide right results. If you’re using an analog unit from longer time, then it will damage the dial pads and accuracy even in difficult condition, along with damaging the dial space with the buildup of inside dial pads.
Verdict: For ease of reading, digital multimeter will provide best and accurate results. A few DMM models will consist an LCD display and a knob that help you to select various ranges like from an analog to digital. The convertor and internal circuitry will help for signal conditioning.

2.How to prevent multimeter from getting damaged?

Never ever overpower the digital multimeter. Always reduce the signal level to minimum safety level before turning on/off of the connected equipment (OR) DUT. This process will prevent any unexpected current or voltage sag or swell from affecting either output or input of the device.

3.Why one should need to have a digital multimeter?

Generally, multimeters are essential to perform any type of electrical work like from installing a ceiling fan to changing a junction box. The digital multimeters are specially designed to measure three main components of electrical energy – volts, ohms and amps along with temperature, capacitance, etc. with accurate readings.

4.How to check whether the multimeter is working or not?

The multimeter which you’re using should read some value within your voltage range (110 – 220V). For example, to check the value of current you need for a battery (1.5V AA battery) connected to resistance (100 ohm). Connect the multimeter to the circuit and it should read value around 15 mA.

5.What is meant by Peak Mode?

Peak mode is used to measure both the extreme positive and negative voltages of a signal. For example, the peak mode of a 120V AC line will be +169 V to -169 V.
