A multimeter is arguably the most important tool an electrician has in their toolbelt and the first thing most reach for in the beginning phases of troubleshooting. When identifying issues with rotary encoders in conveyor systems, the multimeter can help detect a range of problems before turning to more specialized equipment.In this article, we’ll discuss how to use a multimeter to troubleshoot rotary encoders and walk through step-by-step instructions.Understanding Rotary EncodersA rotary encoder...

随着光伏阵列的老化，系统性能可能因众多潜在原因而下降。有些原因是可以预见的，比如污染损耗和阵列的长期退化。还有一些则可能是意外情况，比如旁路二极管故障或模块破裂等。由于 I-V 曲线绘图仪能够记录光伏源的所有电流和电压工作点，这使得它具备识别光伏系统性能下降的各种症状的独特能力。 每个光伏模块的数据表都会提供一个模型 I-V 曲线，它会展示在标准测试条件...

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.

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...
