A digital multimeter (DMM) is the first tool most of us reach for when troubleshooting an electrical issue. It provides a variety of measurement features that can help isolate a problem or narrow down the list of potential issues. Troubleshoot Transient Voltages in VFDs Using a Digital MultimeterWhen troubleshooting a variable frequency drive (VFD), a multimeter is an excellent tool to start with. Variable frequency drives are motor controllers that vary the frequency and voltage of power supplied...

Accurate calibration of pressure switches is a critical step in ensuring process quality and the safe operation of equipment. The setup is like pressure gauge calibration except now a voltage or continuity across a set of switch contacts needs to be read either by a digital multimeter or the calibrator. The purpose of the calibration is to detect and correct errors in the set point and dead band of the pressure switch. Calibrators can save you time by reducing steps and reducing the amount of equipment...

Classic methods for pressure switch testing have been superseded with the introduction of new pressure test tools. Today most pressure switches are tested with a pressure gauge mounted to a pump to supply and measure pressure, and a digital multimeter set to continuity to verify the opening and closing of the switch. The technician or electrician making the test is required to interpret the pressure applied to the switch when the continuity beeper sounds indicating contact closure of the switch....

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...

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. Ready to learn how to safely test continuity with a digital multimeter? Read the Fluke step-by-step...

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...

Hundreds of thousands of new High-Voltage Direct Current (HVDC) power systems are being built across the country, from solar photovoltaic (PV) systems to electric vehicle charging stations (EVSEs). How do electricians stay safe while working on them? In this webinar for EC&M Magazine, sponsored by Fluke, senior power engineer and expert electrical safety trainer Tommy Northcutt discusses what every electrician should know about HVDC power system safety.1. Why is HVDC technology growing? PVs and EVsThe...

Power and distribution panels and their nearby wiring are a frequent starting point for technicians when electrical disruptions require troubleshooting. Voltage and current are two of the most common electrical measurements taken at panels and the surrounding wiring. To isolate specific problems, a technician may also want to test for continuity or measure peak voltage, peak current, minimum/maximum voltage (or current) over time, temperature, harmonics, power factor, transient voltage, temperature...

The mA simulate function of a loop calibrator is very useful for testing and troubleshooting 4 to 20 mA process control loops. In mA simulate, a loop calibrator essentially replicates the function of a process instrument when connected in place of the transmitter. The mA simulate function is often referred to as transmitter simulate on the loop troubleshooting tool. In mA simulate mode, the loop calibrator is technically a mA sink. This means it regulates a programmed mA signal value and draws power...

Many process devices operate and indicate measurements based on an input of a 4 to 20 mA signal. A few examples include control valves, I/Ps, local process indicators, strip cart recorders, controllers and control system input cards. Loop calibrators or other tools with mA sourcing functions are very useful for testing these devices.For example, if testing a current-to-pressure converter (I/P) with a 4 to 20 mA input and a 3 to 15 psi output you would apply input mA signals of 4, 12 and 20 mA and...
