Frequently Asked Questions About Digital Multimeters (DMMs)
What Is a Digital Multimeter?
A multimeter refers to a measuring meter that makes multiple types of measurements, such as alternating current (AC) or direct current (DC) voltage, AC or DC current, resistance, temperature, capacitance, and more parameters. A modern digital multimeter uses digital and logic technology to miniaturize and enable many features in its internal system. With digital technology, digital multimeters can have graphical displays, perform data logging and signal digitizing capabilities, programmability, and communicate with external devices.
How to Read a Digital Multimeter?
Most handheld or benchtop digital multimeters have measurement displays in digits. The number of digits on display usually corresponds to the level of resolution the digital multimeter can measure. Resolution is the level of detail that is quantifiable on a digital multimeter. Therefore, the higher the number of digital multimeter display digits, the higher the resolution. It is common to see handheld digital multimeters with display digits of 3.5 and 4.5 digits. Bench digital multimeters tend to have display digits of 5.5 digits, 6.5 digits, 7.5 digits, and even 8.5 digits.

How to Use a Digital Multimeter?
A digital multimeter is a highly versatile test measurement tool because it can measure multiple types of signals. To learn more about how to make measurements such as voltage, current, 2-wire resistance, 4-wire resistance, capacitance, temperature, diode, continuity check, and the frequency of an oscillating signal, please visit our blog by clicking on the link below.

How to Use a Digital Multimeter to Check for Power?
A digital multimeter can measure current (I) and voltage (V). If you have both measurements, calculating the DC power is simply multiplying both the current (I) and voltage (V) measurements. Most digital multimeters have an internal architecture that inhibits their ability to measure both at the same time. However, if you use a few techniques and the right equipment, you can get a good I and V measurement from your benchtop DMM.
