Digital multimeter FAQs
What is a benchtop digital multimeter?
A benchtop digital multimeter measures electrical stimuli, including voltage, current, and resistance. It’s a diagnostic tool used by electrical and electronic 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 benchtop multimeter?
A digital multimeter is very easy to use. When using a benchtop multimeter, 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, like those manufactured by Fluke, are used by electricians, electrical contractors and HVAC specialists to make measurements and troubleshoot potentially hazardous systems in the field. Benchtop multimeters, like those made by Keithley, 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.
Can Keithley digital multimeters be rack mounted?
Yes, Keithley digital multimeters can be rack mounted with the appropriate kit.
