By Michael Crepps, Fluke Product Application SpecialistPreventive maintenance is critical in industrial plants to ensure the reliability and longevity of electrical systems. Regular inspections and maintenance help to identify potential issues before they become significant problems, minimizing downtime and enhancing safety. A wire tracer is an essential tool for preventive maintenance, allowing technicians to accurately locate and assess the condition of electrical wiring. This application note...

In this guide, we will explore how to use a multimeter to perform various measurements and tests. Multimeters are versatile tools used by electricians and hobbyists alike to diagnose electrical problems and ensure the proper function of electrical devices. We'll explain how to measure AC and DC voltage, test for continuity, measure capacitance, measure frequency, and test diodes. Though the exact procedures may vary slightly depending on the specific multimeter model, the fundamental principles...

Every HVAC technician knows that no two jobs are the same. One day, you might be troubleshooting a failing compressor in a rooftop unit, and the next, balancing airflow in a residential home with uneven heating. Each specialty — residential, commercial, and industrial HVAC — comes with its own challenges and tool requirements.The Fluke 902 FC HVAC Clamp Meter in action.Every technician needs accurate, reliable tools designed for the specific demands of their work. But before choosing tools based...

特别适用于针对太阳能电池阵列和风能系统的室外作业。

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...

T6-1000 PRO 真有效值非接触式电流电压测试仪，带接地线夹和皮带套

Classic methods for pressure switch testing have been superseded with the introduction of new pressure test tools.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....

Fluke FieldSense™ technology offers a safer way to measure voltage by isolating the measurement tool from the voltage source under test. This reduces the risk of electrical shock and arc flash. Through the principle of galvanic isolation FieldSense allows electricians and technicians to measure voltage without exposing themselves to contact points with live voltage. Instead, a FieldSense-enabled test tool such as the Fluke T6-1000 PRO senses the electrical field in the open fork and measures the...

随着能源自主和可再生能源的发展，HVAC 技术人员需要了解如何检修光伏系统

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...
