Set the digital multimeter (DMM) to measure frequency. The steps can vary by meter. Usually a multimeter’s dial will be turned to dc V and the Hz button is pressed. The DMM is ready to measure duty cycle when a percent sign (%) appears in the right side of the multimeter’s display. First insert the black test lead into the COM jack. Then insert the red lead into the V Ω jack. When finished, remove the leads in reverse order: red first, then black. Connect the test leads to the circuit...

Whether you troubleshoot and maintain electrical distribution, HVAC, or rotating equipment you probably use a digital multimeter regularly. You may also use an infrared camera, or thermal camera to help you troubleshoot. The problem: Carrying two separate tools or having to go back to the shop to grab the thermal camera. Adding even more tools to a heavy tool bag or taking time away from the work to be done. The solution: A thermal multimeter, or thermal dmm, is both a digital multimeter and a thermal...

By Brian Harrison According to a Fluke 2019 survey, roughly 50 percent of maintenance and reliability professionals were actively planning Industrial Internet of Things (IIoT) initiatives. This survey preceded the challenges brought about by COVID-19. At the time, more than half of the teams interviewed found the IIoT process to be more complicated than anticipated because of an essential prerequisite—collaboration with other teams and departments. Despite the business disruption caused by the...

Continuity is the presence of a complete path for current flow. A closed switch that is operational, for example, has continuity.  A continuity test is a quick check to see if a circuit is open or closed. Only a closed, complete circuit (one that is switched ON) has continuity.  During a continuity test, a digital multimeter sends a small current through the circuit to measure resistance in the circuit.  A meter with a continuity beeper briefly sounds off when it detects a closed circuit. The...

Steps for using a multimeter in the Diode Test mode.

Steps for measuring ac voltage with a digital multimeter.

Resistance is measured using analog or digital multimeters. These tools also measure current, voltage, and more for various applications. Why measure resistance? To determine the condition of a circuit or component. The higher the resistance, the lower the current flow, and vice versa. In general, the resistance of components used to control circuits (such as switches and relay contacts) starts out very low and increases over time due to factors such as wear and dirt. Loads such as motors and solenoids...

Circuits and equipment may be designed to operate at a fixed or variable frequency. They may perform abnormally if operated at a different frequency than specified. For example, an ac motor designed to operate at 60 Hz operates slower if the frequency is less than 60 Hz, or faster if frequency exceeds 60 Hz. For ac motors, any change in frequency causes a proportional change in motor speed. A five percent reduction in frequency yields a five percent reduction in motor speed. Some digital multimeters...

Turn dial to dc voltage. Some digital multimeters (DMMs) also include dc millivolts. If uncertain of which to choose, start with dc voltage, which handles higher voltage. First insert the black probe into the COM jack. Steps for measuring dc voltage with a digital multimeter Then insert the red probes into the V Ω jack. When finished, remove the probes in reverse order: red first, then black. Connect the test probes to the circuit: black to the negative polarity test point (circuit ground),...

Grid connected photovoltaic systems are growing in importance as sustainable energy sources. The DC power of the solar panels is converted into an AC power by inverters. These are transformerless and, besides generating AC current, also inject a small DC Current. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause additional losses and reduce transformer lifetime. For measuring these DC components, we need a Power Quality Analyzer...
