Digital Multimeter

Digital multimeter is equipment used for various electronic tests. We called it a multimeter due to the design and functionality.

One can use this equipment for multiple purposes, including measuring the DC and voltages, AC voltages and currents, capacities, frequencies, temperature, and resistances.

You can perform tests for the diodes, transistors or check the electronic continuity this device has used everywhere. As compared to the other, digital multimeter is mainly designed to use in any workshop or stationery.

If we talk about the dimension of this device, then let me explain clearly. This equipment is almost 25cm wide, with a height of 10cm and a depth of 30cm. However, most of the users place it on the small stand to check the reading efficiently.

Additionally, the cost of this device varies according to the shop or brand. There is an affordable digital multimeter available in the market with such a fantastic performance.

Similarly, the high price of digital multimeter has high specifications and is based on more advanced features. These days, the digital multimeter is ruling over the market due to the users' affordability and comfortable reading facility.

Moreover, people believe that digital multimeter provides more accurate voltage, current, and resistance measurement.

i). DMM Design and Controls:

The digital multimeter has a fundamental design, with the front screen contains all the specific functions. It has a switch, display, connection, which is used for the test probes.

You can check every reading on display and made the settings through the button below. On the front side, you will have a display, main selection switch, standard connection, high current connection, transistor test connections, and standard ohms, volts, amps connection.

ii). Display:

The display at the digital multimeter is easy to read and simple to handle. It shows the four digits.

The first one will be either 0 or 1 and +/_ indication as well. Furthermore, there will be indicators for the AC/DC, which mainly depends on the model you use.

iii). Main Connections:

You will have the primary connections at the digital multimeter for the probes. It includes:

The first one is common, which you use for all the measurements. It is the negative one with black lead and probe.

The next is for volts, ohms, frequency. This is the positive one with red lead and probe.

Another one is for amps and milliamps, which is for the current measurements, take the red lead and probe.

The last one is the high current, which requires careful measurements.

How to use a digital multimeter?

First of all, if you get a new multimeter, then you need to install the battery to start it.

The details regarding it are available on the instructions given by the manufacturers. However, while using the multimeter, the following are the steps necessary to follow:

Please switch it on.

Make sure to insert the probes in the right connections.

Don't forget to set the switch to the measurement type to get accurate readings.

If possible, enable the settings not to read zero so you can find the significant number easily.

Place the probes into measurement sockets and change the range to maximum once the reading is completed.

What Is Better About Digital Multimeter?

Digital multimeters are more accurate.
It has low error and interpolation chances.
In this multimeter, all the parallax errors are removed.
It does not have any moving parts, which makes it free from any shock failure.
With this digital multimeter, you will easily read the measurements.
Due to the LCD, you will be able to get accurate readings on the go.
It has a small size so one can easily carry it anywhere.
The input impedance of this multimeter is high.
Due to the auto polarity function, don't worry. The multimeter will never connect to any wrong polarity.

Who Should Get A Digital Multimeter And Why?

i). Accuracy

If you are looking for a device that provides accurate results without any errors, then a digital one is for you.

This device does not have any needles, which could disrupt the precise measurements without any parallax error.

ii). Automatic

Are you looking for quick reading and do not have time to find measurements by checking the needle?

Then the digital multimeter is the best one for you. It works automatically and does not waste your time in eliminating any error while reading.

Analog Multimeter

This is the PMMC meter, which is based on the d'Arsonval galvanometer principle. The testing instrument is used to measure the current, voltage, frequency, signal power, and resistance.

However, finding an accurate reading at this multimeter could be hard for beginners. These days the usage of the analog multimeter is low due to the manufacturing of digital multimeter.

But no matter how advanced the technology gets, but some people still rely on this device. This multimeter contains a needle that shows the measured value on the scale.

When the current passes through it, a coil starts moving in the magnetic field, and the indicating needle is attached to that coil. If you saw the coil rotating at some angle, then that is due to the deflecting torque.

To maximize or you can control the torque, hairsprings are attached with it.

i). Errors:

The main error that occurs at the analog multimeter is the parallax error. One has to take care of this error while reading the measurements on this meter.

The eye should be placed at the right angle of the meter containing back markings while viewing the multimeter. However, if you find the measurements by keeping an eye on one side, the reading will be incorrect.

ii). Analog multimeter ranges:

The analog multimeter has different ranges. The variety of ranges available at the multimeter are defined in terms of FSD (full-scale deflection).

Here are the ranges you will find at the multimeter:

AC Voltage includes 10V, 25V, 100V, 250V, 1000V.
DC Voltage includes 2.5V, 10V, 25V, 100V, 250V, 1000V.
DC Current includes 50µA, 1mA, 10mW, 100mA.
The resistance voltages are 100R, 10,000R.

How to use An Analog Multimeter?

Here are the simple steps which you need to follow while using the analog multimeter:

First of all, place all the probes at the right connection to avoid damage.

To find the accurate measurement, switch to the right measurement type.

Moreover, while selecting the range, make sure that it is above the one expected. However, you can reduce the multimeter range later.

Improve the range to get the best reading. Once the task gets complete, don't forget to place the probe back and maximize the voltage.

What Is Better About Analog Multimeter?

The analog multimeter is affordable.
It has a quick response.
This multimeter does not need any battery installation unless you need to measure the resistance.
It shows accurate reading while checking the diode.

Benefits Of Analog Multimeter:

Following are the benefits of the analog multimeter:

Who Should Get An Analog Multimeter And Why?

i). High Sensitivity Tasks

For those who need to deal with high-end circuits and look for a multimeter for susceptible measurements, an analog multimeter will be best for you.

The analog multimeters show accuracy while measuring the diodes.

Most technicians preferred to use an analog multimeter because they believe that the needle movement in the analog will show some points, which you can't see with the digital multimeter.

ii). Affordable

Furthermore, if you have a low budget and looking for a multimeter to measure the susceptible areas, choosing the analog multimeter will be the best option.

Some people require the multimeter for their everyday use or some high-end tasks but did not have enough money to buy the digital one should go for the analog.
