A digital multimeter or DMM is used for measuring and verifying multiple electrical quantities, such as voltage, current, and resistance.
Most technicians and electrical engineers use it as a diagnostic tool always.
It is an instrument that combines the features of a voltmeter, ammeter, and ohmmeter.
The digital multimeter typically includes probes, clamps, or leads. They are inserted into inputs on the instrument and then connected to the device under test to complete measurements.
MEXTECH is a reputed name in the field of digital multimeters. They make good-quality equipment for technicians.
Digital multimeter- why it is used for?
A Digital Multimeter is primarily used to verify one of the three aspects which are Voltage, current, and resistance.
Digital multimeters are used in the lab or field to verify the state of a circuit or system for safety purposes. These devices essentially help engineers to check whether a device is safe to work on or not.
One can find a range of digital multimeter manufacturers, who offer different types of digital multimeters suiting the needs of customers.
Types of Digital Multimeters
General purpose digital multimeter
General purpose digital multimeter is for beginners. It is used for troubleshooting simple circuits and getting a general idea of what is and isn’t working. Though the readings are foolproof, these devices are not rated high in terms of accuracy.
They are also called digital voltmeters, handheld digital multimeters are used by electricians, electrical contractors, and HVAC engineers to measure and troubleshoot potentially hazardous systems. When mobility is your priority, you should use handheld digital multimeters.
Bench or commercial digital multimeter
They are known by both names. Electrical and electronic engineers use these multimeters to do more advanced measurements.
These instruments are very precise, and they bring a wide range of advanced functionality, such as the ability to program automation and to measure low-level or transient signal behavior.
You can buy good-quality equipment from the best digital multimeter company.
Compact digital multimeter
Compact digital multimeters are multi-channel multimeters. They are used in manufacturing applications where you need precise measurements in a place where you have limited equipment space. It is possible to squeeze tens or even hundreds of channels into a single mainframe by embedding cards with mux and switches.
Using a compact digital multimeter is easy. You should check for physical damage on your digital multimeter and DUT. Then, you should connect the appropriate probes to the digital multimeter. It is essential to keep track of color-coded inputs while doing this.
One should configure digital multimeter settings to the desired mode, e.g., resistance, voltage, or current.
It is important to verify the functionality of the digital multimeter by testing it with a known source of voltage.
You need to measure the reading by placing them on the positive and negative terminals of the DUT.
Keep a close watch on the safety warnings while working with digital multimeters. These versatile equipment are widely used in a range of industrial and mechanical processes where you are required to measure electrical currents and voltages.
