Oscilloscope probes are commonly used alongside other measuring instruments to monitor voltage, frequency, and waveforms. Proper use of the probe ensures greater stability during testing and facilitates more effective signal analysis.
This guide explains common communication interfaces used in industrial equipment and test systems, outlining their main characteristics, typical use cases, and practical selection points.
Oscilloscope amplitude readings can look lower than expected when the instrument bandwidth is not suitable for the signal. This article explains the basic causes and practical bandwidth choices.
Continuous monitoring of three-phase power consumption enables businesses to track voltage, current, power, and energy usage in real time, thereby identifying peak load periods, abnormal consumption patterns, and changes that could impact equipment
An analog multimeter needle moving backward during voltage measurement does not necessarily indicate a defective instrument. Understanding the operating principle, common causes, and proper inspection procedures helps prevent misdiagnosis and unnecessary repairs.
A power quality analyzer can record the entire sequence of events—before, during, and after—a momentary power outage. Based on the captured voltage, current, and waveform data, engineers can pinpoint whether the fault originated from the utility grid or the facility's own electrical system, rather than relying on speculation based solely on external symptoms
You can easily check for weak or unstable power right at home using a multimeter. After just a few minutes of measuring the voltage, you will be able to determine whether the power supply is experiencing a voltage drop or if the issue lies with the wiring, the outlet, or the appliance itself.
"Silent capacitor burnout" refers to a phenomenon where a start capacitor gradually loses capacitance without exploding or emitting smoke, making it difficult for the user to detect the issue until the motor has sustained severe damage. The appliance continues to operate but runs sluggishly, overheats, and consumes twice the normal amount of electricity. Without periodic inspections, a component costing only a few tens of thousands of dong could force you to replace the entire motor, air conditioner compressor, or ceiling fan an expense running into the millions.
An analog multimeter can still be used to quickly check if a capacitor is shorted, open-circuited, or capable of charging and discharging. However, if precise capacitance measurement or an assessment of capacitor quality is required, a digital multimeter or LCR meter will yield more reliable results
By simply measuring the rotational speed (RPM) and comparing it against design specifications or historical maintenance data, engineers can detect signs of belt slippage, speed reduction, or power loss without needing to disassemble the motor
