Digital Multimeter FAQs What is a digital multimeter? A digital multimeter measures electrical stimuli, including voltage, current, and resistance. It’s a diagnostic tool used by technicians and electrical engineers daily and combines the features of a voltmeter, ammeter, and ohmmeter. How do digital multimeters work? Digital multimeters attach to probes, leads, or clamps, which are connected to an electronic device. They then measure the device’s voltage, current, or resistance and use an analog to digital converter to present a value on the display. How do I choose a digital multimeter? When it comes to choosing a digital multimeter, there are a number of factors to consider, starting with where you will be using it. You’ll also want to look at accuracy, speed, and the number of channels needed to complete your job. How do you use a digital multimeter? A digital multimeter is very easy to use. When using a benchtop DMM, you select the correct measurement mode, then attach probes, clamps, or leads to both the DMM and the device under test to make a measurement. What is a digital multimeter used for? A DMM is often used to verify one of the factors of Ohm’s Law (voltage, current, and resistance). Engineers in the lab and in the field also use DMMs to verify the state of a system or circuit for safety purposes. What’s the difference between handheld and benchtop digital multimeters? Handheld digital multimeters are used by electricians, electrical contractors and HVAC specialists to make measurements and troubleshoot potentially hazardous systems in the field. Benchtop DMMs are instruments used by electrical and electronic engineers to perform more advanced measurements and gain confidence in their designs. These instruments are extremely precise and have a variety of advanced functionality, including the ability to program automation, slow or speed up measurements to observe low-level or transient signal behavior, and interface with other instruments. How do I measure current with a digital multimeter? A digital multimeter measures current by becoming part of a circuit and measuring the current as it passes through the instrument. Learn more about how to break your circuit and take measurements with step-by-step instructions for how to measure current with a digital multimeter. Digital multimeter safety tips Digital multimeters are generally safe provided they are used according to the instrument’s instructions and safety best practices are followed. Below are a few tips to ensure your safety when using a digital multimeter. Know your electrical parameters. Any DUT will have a set of electrical parameters, which are associated with CAT ratings. Never use a DMM that isn’t rated for your job or test environment. Wear the appropriate PPE. Before touching your DUT or instrument, make sure you have the proper PPE, which typically includes gloves and rubber-insulated mats. Test in a safe environment. Keep all work surfaces clean and dry and never work in an environment with flammable liquids or vapors. Power up and down safely. Never connect or disconnect probes or leads while they are connected to a voltage source. And don’t touch exposed connections and components when power is present. Use the correct inputs for a signal: Always use the appropriate connectors for the signal you’re measuring (current or voltage) and for the right level of current you’re measuring. Set the appropriate range: Before making a measurement, make sure you set the appropriate range to avoid potentially damaging equipment or causing injuries.
