Both Shore A and Shore D are used to measure material hardness, but each scale is suited to a different group of materials. Soft rubber, silicone, or elastic gaskets are typically tested using Shore A, whereas hard plastics, engineering plastics, and materials with low deformation are better suited to Shore D

Equipment restarts in a factory setting can be attributed to voltage sags, momentary power outages, electrical noise, overheating, or hardware faults. For incidents that last only a few power cycles, a power quality analyzer can capture voltage, current, and waveform data at the exact moment of the reset, thereby helping engineers determine whether the power supply is the cause

Record length is the number of data points stored during a single waveform acquisition. When the sampling rate remains constant, a longer record length allows the oscilloscope to capture the signal over a longer period of time. Record length affects the actual sampling rate, the ability to maintain a high sampling rate over an extended period, and the amount of data available for electrical waveform analysis.

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.

Learn how to choose and use a feeler gauge correctly to reduce measurement errors during mechanical inspection and maintenance.

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
