What Is A Multimeter?
A multimeter is an electronic measuring, recording, displaying and integrating instrument used mostly for measuring electrical parameters such as voltage, current, resistance and frequency.
It also performs some electronic-related tests such as continuity test and diode test. Other than this, it measures capacitance and temperature as well.
It’s, therefore, a multi-purpose instrument with a variety of applications. They have either LCD display or LED display for indicating the measured values. Some of the screens have a backlight to enhance visibility in dark areas while others do not have. They measure continuous or analogue signals by sampling them at different rates.
Types of Multimeters
A digital multimeter comprises an LCD display, selector knob for different range selection, signal conditioning circuit and analogue to digital converter. The analogue signal is converted to a digital signal by the sampling process.
Which determines the resolution and accuracy of the displayed digital data. Also, the digital data is displayed on an LCD display while the selector switch is used to select between different ranges on the Multimeter. Finally, this Multimeter has a faster response time compared to the analogue type.
It’s made up of a moving pointer due to the motion of a moving coil and indicates the readings on a graduated scale. A wired coil is placed between permanent magnets and part of the current to be measured passes through these types of coils.
And it generates a magnetic force which repels or attracts that of the permanent magnet causing motion that is proportional to the current flowing through the wires. The wired coils have the pointer attached to them through a pivot that is attached to a hairspring.
This spring dumps away frictional force and counters the motion due to magnetic fields.
Buying Considerations of Best Multimeter for Electronics
When buying the best cheap multimeter, you need to it wisely by checking some crucial factors, which include:
Electrical Parameters Specification
Examples of electrical parameters include the current, voltage and frequency measurements. The current can either be alternating or direct current for voltages and currents. Frequency is primarily determined by the presence of inductance and capacitance in a circuit configuration that has an alternating current signal.
For the case of voltage and current, they relate to each by resistance. These are the key points you need to have in mind first before choosing the best Multimeter.
When you want to make observations about a given reading of the above electrical parameters, you are required to have a multimeter with higher voltage and current reading than what you want to measure.
This feature is crucial since it will always ensure that your Multimeter doesn’t suffer from over-voltages and loading effects that result from excessive currents. Other than this, the excessive current through a given ampere scale can be hazardous to your Multimeter and you as well.
The reason here is that there can be possible fire if the Multimeter is not well fused. The True RMS value measurement is very crucial for alternating current voltage and current. This measurement will help to account for DC voltage or electrical-current components if any are available.
Also, frequency is a critical factor of which to measure since AC bridges are utilized internally in the Multimeter. Always ensure that the frequency measurements you want to make are within the range of that Multimeter you wish to acquire.
Resolution of the Multimeter
Here, multimeter resolution simply means the lowest possible unit up to which you can get quality signal strength. It’s also a noticeable change in the output signal when there is a slight change in the input signal.
This implies that you have to look at the sampling rate of a digital multimeter. The sampling rate is a technique used to switch a time-varying electrical signal and convert it into its digital equivalent, preserving the previous information in the analogue signal.
Also, the rate at which a signal is sampled determines the resolution, hence the accuracy of the electrical signal. Testing the electrical signal faster implies that data from the analogue signal is converted to a digital signal.
Thus even the least bit of information that was in the analogue signal can be displayed. Slow sampling means that most parts of the analogue signal are chopped off and hence losing some of the information.
This feature implies that the least bit of the analogue signal cannot be displayed and thus, making the Multimeter less accurate due to its low resolution. Resolution is, therefore, something that you shouldn’t ignore while buying the best digital multimeter, especially when you want to make susceptible measurements.
Here, the impedance of an electrical device refers to the total opposition to current flow due to resistance and reactance. Impedance in a circuit is realized by a parallel and series combination of resistances, inductance and capacitances.
This constitutes total opposition to current flow. Also, you need to note that multimeters are designed with different input impedance’s for various purposes.There are two types of impedances, that is low and high impedance.
The low input impedance is used mostly for maximum power transfer that ensures there is a perfect matching of impedances between the source of power and the destination. By matching low impedances, you will ensure that the energy source is not overloaded by the load.
Low impedance on multimeter input is used to remove high voltage spikes from the voltage rails, which drops the voltage faster. High impedance is also advantageous on the input of the Multimeter since it ensures that most of the weaker signals from the source are seen on this impedance.
Through this, you will reduce the chances of signal attenuation caused by voltage drops resulting from power dissipation on low impedances. High impedance on the input terminal of the Multimeter also ensures that no current or very minimum currents are drawn from the source.
This reduces the noise seen by the Multimeter and therefore, giving out a very stable signal.
Important FAQs about Best Digital Multimeter
Q: 1. Does a multimeter come with over-load or over-voltage protection in it?
A: Most multimeters are fused to prevent them from turning into flames or damaging other parts of the electronics from where they are connected. There are different types of fuses and manufacturers put them in different multimeters based on where they will be used to make measurements.
The fuses can be slow-burning, fast-burning or ant-burning fuses. Slow-burning fuses are applied where the current draw is almost the same to the rated current, which causes slow burning of the electrical fuse which eventually dies off with time disconnecting the circuitry.
Fast-burning fuses burn immediately when the current drawn exceeds the limit. Anti-burn electrical fuses are made of ceramics which don’t explode when the electrical fuse draws excess current, which can cause a possible fire outbreak.
Also, these fuses mostly serve to protect the best multimeter for electronics against excessive currents. Over-voltage is countered by NTC thermistors which increases resistances when excessive currents flow through them due to high voltage levels.
This feature regulates the amount of voltage seen by the Multimeter as the input. Therefore, a good multimeter should come with these features to be safer while using it.
Q: 2. What is considered when you want to grab a high accuracy multimeter?
A: Accuracy is the quality of a measurement to be as close as possible to the standard value. To grab a high-quality multimeter from the store, you need to consider several critical factors.
Some of the factors that determine the accuracy of measurement include the sampling rate of the analogue to digital converter used in the Multimeter and the input impedance of a given range.
The faster the signal is sampled, the more accurate is the digital output displayed on the LCD display. Therefore, sampling time in every second should be considered if you are checking for accuracy, and this is usually indicated in the datasheet.
In the sampling process, the analogue signal is converted to the digital signal based on the number of the bits the sampling IC used in the Multimeter. Impedance is also important determining the accuracy of the measured signal.
The high input impedance implies most of the signal data from the source is seen at the input of the next stage. This reduces the possibility of signal noise at the input port.
For high accuracy signals at the output of a multimeter, the high input impedance is very crucial since it takes small currents from the source and delivers most of the signal data to the destination. It’s, therefore, recommended to look at these factors.
Q: 3. Can a multimeter battery be recharged?
A: Most of the portable hand-held multimeters use a 9 volts battery. When this battery gets discharged, it’s disposed of, and a new battery is re-inserted into the Multimeter. Some multimeters use rechargeable batteries which are recharged separately or through a USB cable when they get discharged.
All these types are found in the electronics shops. Therefore, a choice is always left to you to choose which one to grab. Also, there are different technologies used for manufacturing the batteries used in multimeters.
Some of these batteries include; lithium-ion, lithium polymer, dry cells, etc. These batteries have different lifespans and power capability. A lithium polymer battery has a longer service time compared to the other two types of batteries.
Thus, this is something you should go for if you are looking for a long-lasting battery.
Q: 4. What is the effect of measuring small magnitude value on large magnitude scales?
A: Before putting the test probes on the joints where measurements are to be taken, you should ensure that you have selected the suitable range in case you are using a multimeter that doesn’t have auto-range.
For auto-range best inexpensive multimeters, you don’t have to worry about the range of which you are using because the Multimeter adjusts itself automatically. Measuring low-resolution values on high magnitude scales reduces the accuracy of the measured values, and therefore, it’s not the best thing to do.
Let’s Learn How to Use a Digital Multimeter
From this guide, it can be concluded that multimeters are available with different functionalities based on the technologies used to manufacture them. A typical multimeter measures voltage, current, resistance, continuity and diode testing.
The additional measurements; data storage, holding of the data, automatic turn off in idle mode among other features bridges a gap between different types of multimeters. Other than this, the Multimeter’s performance characteristics are crucial depending on the type of measurements you want to make.
For instance, very sensitive and insensitive measurements. The resolution, input impedance and accuracy play a crucial role in determining how much sensitive/accurate or insensitive your multimeter output data is.
Therefore, having a look at these factors is the right path to follow if you aim to buy the best budget multimeter.
