Do you know what is multi meter & what are the types of multimeter ? Today we will read information related to multimeter.
Friends, you may have seen a multimeter in many stores, but you might not know what a multimeter is. Multimeters are used to check the electrical signal in mobile repairing, TV repairing, or repairing any electric product.
If your phone is defective or if any other electrical device is damaged. So you must have gone to the repairing center, then you must have seen that in the repairing center a person uses a device to check the phone battery or to do any other electrical activities.
Which is small in size and by connecting the two wires to the mobile battery or any other electrical device, the electrical activities in the device are noted.
So, let's know "what is multimeter" and how many types of multi meters are there. This post can be very useful for students. Because multimeter is the complete chapter in 12th physics. With the help of this post, students can learn about multimeter.
What is Multimeter ?
A multitester or multimeter is a device that can be used to collect data about electronic circuits. A basic multitaster can measure resistance, current voltage and continuity. While more advanced versions may be able to provide additional data.
The multitester device is operated by a battery. It consists of two probe screens connected to a central pack. Which can be digital or analog. This device has many buttons or switches. Which can be used to set the type of measurement.
Types of Multimeter :-
Friends, you have already read what is multimeter? Now we will talk about the types of multimeters. By the way there are two types of multimeter commonly. Which includes analog multimeter and digital multimeter. Under this, other multimeters have been developed. So let's know about these two types.
What is Analog Multimeter ?
Analog multimeters are such devices. These are used to measure electrical quantities such as voltage, current, resistance, frequency and signal power. Basic functionality includes measurement of capacitance in volts, resistance in ohms and current in amps.
Analog multimeters are used to find electronic and electrical problems. Advanced units in analog multimeter come with more features such as capacitor, diode and IC test mode.
Typical measurements performed by an analog multimeter include DC voltage, AC voltage, DC current, AC current, frequency range for AC currents, and decibel measurements. The analog multimeter currently measuring may have a current clamp.
Which is built-in or configured as a probe. A clamp is a sensor that is clamped around the wire.
When searching for an analog multimeter, it is important to consider that an analog multimeter displays the values ​​through a dial for whatever value is being measured.
Usually an analog multimeter has a moving indicator or needle . Analog multimeters are typically bench tops or hand held. Bench top models can also be portable using handles and wheels.
Hand held multimeter can be operated with one hand. Common features for analog multimeters include battery power, overload protection, temperature compensation, reflective scale, range switch, diode test, and battery test.
Devices with battery power can be operated without a plug in power. Multimeter with overload protection has a fuse or other method to protect the meter.
Temperature compensation devices consist of programming or electrical equipment. Which are designed to combat known errors due to temperature changes.
A range switch is used to select the appropriate range of units to be measured in an analog multimeter. There are methods to test diode operation in a device with a diode test. Battery testing devices have methods for testing battery operation.
Detection analog multimeter :
Guys what is analog multimeter? After knowing this, you can tell us how to identify the analog multimeter. Friends, multimeters in which needles are used to show parameters. They are analog multimeters as shown in the picture below.
What is Digital Multimeter?
A digital multimeter is one of the most widely used pieces of test equipment today. Digital multimeters are available at very low cost.
These digital multimeters can provide much higher accuracy when measuring parameters within electronics or electrical circuits. Consequently the digital multimeter is one of the most indispensable pieces of test equipment available today.
Originally analog multimeters were used. But they are rarely used these days. Because digital technology has made digital multimeter cheaper. Able to provide many more capacities beyond measuring current, voltage and resistance.
Digital multimeters can measure various parameters within an electrical circuit. Basic digital multimeter can measure amps, volts and ohms. As the old analog multimeter did.
But with the ease of incorporating further functionality into an integrated circuit, many digital multimeters are also capable of performing many other measurements. Many of them include functions such as frequency, continuity, capacitance, temperature and often many other measurements.
Switches and controls are usually set with the main limit switch in the central position within the multimeter panel. The display of the switch on and off is usually positioned at the top of the device. So that it is easy to see and it is free from obscuring by the lead and it can also be seen whether the switch is operating or not.
Any additional switches are usually located around the main switch. Where they can be reached very easily. Connections for test leads are normally located below the front panel of the meter. In this way, the connection of leads can be reached easily. Leads do not interfere with the operation and visualization of switches and displays.
Digital multimeters are very versatile testing instruments. With the development of digital technology, many meters are capable of providing additional measurements beyond the original voltage current and resistance. When purchasing a digital multimeter it is a selectable that the multimeter you want to buy can measure the parameters that can be envisaged when needed.
Detection of digital multimeter:
Guys what is digital multimeter? After knowing this, you can tell us how to identify digital multimeter. Friends, multimeter where a digital screen is given to show the parameters. It is a digital multimeter as shown in the picture below.
