Glossary articles

Article

What is true-RMS?

The need for true-RMS meters has grown as the possibility of non-sinusoidal waves in circuits has greatly increased in recent years. Some examples include variable speed motor drives, electronic ballasts, computers, HVAC, and solid-state environments.

Article

What is a diode?

A diode is a semiconductor device that essentially acts as a one-way switch for current.

Article

What is Ohm’s Law?

Ohm’s Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.

Article

What is duty cycle?

Duty cycle is the ratio of time a load or circuit is ON compared to the time the load or circuit is OFF.

Article

What is a clamp meter?

Clamps measure current. Probes measure voltage. Having a hinged jaw integrated into an electrical meter allows technicians to clamp the jaws around a wire, cable and other conductor at any point in an electrical system, then measure current in that circuit without disconnecting/deenergizing it.

Article

Tips for choosing a clamp meter

Fluke’s assortment of clamp meters has been engineered to address a wide variety of needs, from routine tasks to specialty projects.

Article

What are Hall Effect (ac, dc) clamp meters?

Hall Effect clamp meters can measure both ac and dc current up to the kilohertz (1000 Hz) range

Digital multimeters

Article

Clamp Meters vs Multimeters

A digital multimeter is essentially a voltage-measuring tool with some current abilities. A clamp meter is basically a current-measuring tool with some voltage abilities. They are distinctly different instruments, each with its own advantages.

Why digital multimeter accuracy and precision matter

Article

Guide to Digital Multimeter Safety

Take digital multimeter safety precautions to handle the conditions found in your work environment. Understand multimeter CAT ratings and ingress protection (IP) codes.

Industrial imaging

Article

Expediting air leak detection

Even the smallest air leaks can compound product and energy waste and lost production time—especially for a production line that cannot function without compressed air to run its tools and processes.

Article

How to detect compressed air, gas and vacuum leaks AND find hidden profits

What if there were a leak detection technology that could pinpoint the precise location of a leak from up to 50 meters away? The Fluke ii900 Sonic Industrial Imager, a “gamechanger” in the pursuit of finding compressed air leaks.

Article

How air leak detection equipment prevents downtime

Find out how air leak detection equipment prevents downtime for a 150,000 square foot plant that runs approximately 400 tools on compressed air, produced by a 200-horsepower compressor.

Article

How to prioritize the leaks in your compressed air system using LeakQ

If your compressed air system is under-performing, your connected equipment will be too. Learn how to monitor and prioritize which air leaks to fix using the Fluke ii900 LeakQ mode.

Insulation testers

Article

What is an insulation multimeter?

The Fluke 15x7 Series Insulation Multimeter is a new category of test tool that combines a full featured True RMS DMM and a megohmmeter. It's an integrated tool for maintaining and troubleshooting motor systems, electrical distribution, and production equipment.

Article

Article

Insulation tester vs megohmmeter

What is the difference between an insulation tester and a megohmmeter? Compare insulation meters, testers, megohmmeters, and meggers to learn about what's best for your needs.

Oscilloscopes

Article

How to read a waveform on an oscilloscope

Oscilloscopes sample signals as they change over time and then plot those signals on a display. The amplitude of the signal is plotted on the vertical axis and time is displayed on the horizontal.

Article

Capturing the elusive waveform anomalies with the ScopeMeter® 190C Series

Find out how the pass/fail testing function captures random glitches.

Article

Oscilloscope vs multimeter: choosing the right tool for testing and troubleshooting

The difference between an oscilloscope and a digital multimeter (DMM) is simply stated as pictures vs. numbers. Learn more, including when to use each.

Power quality

Article

How power quality issues affect the plant and how to get rid of them for good

The electrical power issues that most frequently affect industrial plants include voltage sags and swells, harmonics, transients, and voltage and current unbalance. The proper tools to correct these issues include knowledge and electrical test instruments ideally suited for each task.

Article

Common Power Quality Factors Affecting Transformers

Transformers supplying nonlinear loads should be checked periodically to verify operation within acceptable limits. Transformers are also critical to the integrity of the grounding system.

Article

What is power factor and why is it important?

What is power factor and why is it important? Learn how to calculate the power factor formula, each component of the equation, and why it matters.

Article

Why peak demand management matters

Temperature

Article

How to get great results with an infrared thermometer

Infrared (IR) thermometers enable you to measure temperature quickly, at a distance, and without touching the object you're measuring. They are so useful, easy, and even fun to use that they have become as common in kitchens as they have on factory floors. Infrared thermometers are often used to find overheated equipment and electrical circuits, but they have hundreds of other uses.
