What is a digital multimeter (DMM)? How does a digital multimeter differ from an analog version? Is it really necessary to measure resistance, current, and voltage? This article takes a look at KLEIN TOOLS digital multimeter review.
The KLEIN Tools digital meters are simple, accurate tools designed to measure voltage to current, frequency to resistance, and capacitance to temperature. They also include functions such as continuity testing, diode tests, and oscilloscopes for troubleshooting.

What is a Digital Multimeter?
A digital multimeter is a tool that measures electrical values in the form of numbers on a display screen. It can be used to test voltages, currents, resistances, frequencies, capacitances, inductances, diodes, transistors, LEDs, relays, thermocouples, and other electronic components.
How Do They Work?
Digital multimeters use two main technologies:
- Analog-to-digital converters (ADCs) convert analog signals into digital ones. These are usually built using integrated circuits or microprocessors.
- Digital-to-analog converters (DACs) convert digital data into analog signals.
These devices are often called “converters” because they change one type of signal into another. A converter changes a voltage into an analog signal. For example, a DAC converts a digital value into an analog voltage.
An ADC is like a microphone that records sound waves. The output of the microphone is converted into a number by the ADC.
A DAC is like a speaker that plays back sounds. The input of the DAC is connected to a source of audio information. The output of the DAC is converted into a number. It’s important to understand how these devices work before you buy them. You need to know what kind of measurements you want to make and whether your device has the right technology to perform those tasks. 
Why Would I Need a Klein Digital Multimeter?
If you own a home electronics store, chances are good that you sell a lot of equipment that requires electricity. And most of that equipment needs to be tested periodically to ensure its performance.
You could hire someone to do this job, but why not let a digital multimeter do the job instead? In addition to checking voltages, amperes, and ohms, a digital multimeter can help you diagnose problems with various electronic components. 
For example, it can tell you if a relay is open or shorted. Or it can show you when a transistor turns off.

Some digital multimeters even allow you to connect them directly to a circuit board so you can read voltages and currents without having to remove components first.
Klein Tools Digital Multimeter
The Klein Tools multimeter mm400 is a compact unit that offers many features for measuring different types of electrical values.
This model includes a 3-digit LED display, a 1/10th scale meter, and a range selector switch.
Let’s take a closer look at some of the features of this digital multimeter.
3-Digit LED Display
This digital multimeter displays three digits per line. Each digit represents a separate measurement.
1/10th Scale Meter
This digital multimeter allows you to view very small amounts of power.
Range Selector Switch
The range selector switch lets you choose between several ranges of measurement.
This feature helps you identify which wires are connected to each other.
This function tests the voltage across a resistor.
This feature tests the current flowing through a conductor.
This test checks resistance from 0 to 10,000 Ohms.
This capability allows you to measure capacitors up to 100 pF.
The Klein Tools digital multimeter is a great tool for testing electronic circuits. It also works well in diagnosing problems with appliances such as refrigerators, air conditioners, and washing machines.
Knowing which is the best multimeter for home use will help you if you want one for home.
The Digital Multimeter works better than Klein tools 600v 10a manual ranging multimeter, so consider things when choosing. I hope this review has helped you learn more about it and decide if you’re going to buy it or not.
